CHAPTER 23

THE BEST CONTROL FOR

MOSQUITOES

Ollie and Sven are on a fishing trip in Minnesota and woke up to see shadows on the wall of their tent.  Ollie looks out and sees two giant mosquitoes arguing.  The first one says, “Should we eat them here or take them home?”  The other mosquito thinks a minute and then says, “ Let’s eat them here.  If we go home, the big mosquitoes will take them away from us!”  

A MOSQUITO DIAGRAM

Mosquitoes can be found all over the world from the Tropics to the Arctic.  Some mosquitoes can be found 200 miles from their birthplace.  One species of Anopheles frequently becomes frozen but after gradual thawing revives and is capable of laying eggs.  Of all the harmful creatures on earth, this little “vampire” probably poses the greatest threat to mankind.  There are more than 3,450 species in the culicid, or mosquito family, worldwide and mosquito-borne diseases infect about 700 million people each year and kill 3 million according to the Centers for Disease Control.  The U. S. and Canada spend about $150 million each year trying to control mosquitoes with poison.  Residents spend more than that on repellents, insecticide poisons, screens and other products in the vain attempt to control mosquitoes.  They can be easily destroyed with diluted Kleen Kill® enzymes, but I worry at the loss of non-target beneficials.  Only the females bite and then only when they are actively reproducing.

Life History of the Malaria Parasite

(Plasmodium vivax) in Man and

the Anopheles Mosquito

  Note:  By 1995 at least 1 of 4 species of the Plasmodium parasite that infect humans, e.g., Plasmodium vivax, P. falciparum, P. malariae and P. ovale, were found living in the blood of nearly 300 million people.  Malaria is transferred to humans only via mosquitoes and now affects 300 - 500 million new people per year and kills 1.5 to 2.7 million people per year.  Quinine no longer can control malaria - the disease has developed resistance to it.  Malaria is found in at least 102 countries.  In 395 A.D. 330,000 acres of farmland in Rome’s Compania region were abandoned due to a malaria epidemic - Rome fell 81 years later.  

  PEST OVERVIEW

General Description

  Mosquitoes are blood-feeding ectoparasites of people and animals.  The English call mosquitoes “gnats”.  There are about 100 trillion mosquitoes with at least 3,450 different species in the world.  They are found from the tropics to the Arctic regions.  All of the families belong to the order Diptera and are related to house flies, gnats and midges.  What makes mosquitoes different from all other flies is the presence of a long, piercing mouthpart called a proboscis and the scales on the hind margins and veins of their wings.  Morphologically, mosquito males differ from females in that they have feathery antennae, long feathery palps and smaller mouthparts.  Mosquitoes develop through complete metamorphosis and have four distinct states: egg, larva or “wriggler”, pupa or “tumbler” and adult.

Mosquito eggs can be classified into three groups: 1.  eggs laid singly on the still or very slow-moving water surface (Anopheles), with each egg having a series of “floats” along its perimeter; 2.  eggs laid in groups forming rafts made by the adult females that float on water surfaces (Culex and Culiseta); and 3.   eggs laid singly out of the water in the mud (Aedes and Psorophora).  Mosquito larvae are aquatic; they feed on water mites, water fleas, algae, protozoans and minute organic debris by sweeping the food into their mouths with a pair of feeding brushes.  Mosquito pupae also live in the water.  Adult mosquitoes are small, about 1/8" long, with a single pair of membranous wings and are free living.  A typical mosquito weights about 2.5 milligrams, or about 20,000 mosquitoes per pound.  Males do not feed as adults, but females of most species require a human and/or animal blood meal before oviposition, utilizing the protein in blood to produce their eggs and bring them to maturity.  There are an estimated 10 trillion mosquitoes produced just in the U. S. each summer with about 170 species.  To give you some idea how many 10 trillion is - that amounts to 41,000 mosquitoes for every man, woman and child or enough to fill the entire Grand Canyon!  A mosquito’s brain is the size of the period at the end of this sentence, yet it has outwitted man since the dawn of recorded history!  

Mosquitoes seriously harm vast numbers of people worldwide by transmitting pathogenic organisms that cause disease and death, especially in tropical areas.  Including Eastern, Western, California and St. Louis encephalitis, heartworm, malaria, yellow fever, dengue and filariasis.  Malaria is a constant threat even in the United States where known vectors exist.  Malaria, among all insect-borne diseases, has been the most deadly in modern history.  During this century alone it has killed between 100-300 million people, mostly babies and small kids and it infects and debilitates hundreds of millions of others each year per WHO!  CNN Trivia 2/4/98 noted that 700,000,000 people a year are infected by diseases carried by mosquitoes.  In comparison, only 21 million people died in combat in World War I, World War II and the Korean War combined.  Over 60 species of Anopheles mosquitoes are known to be capable of transmitting malaria.  Travelers returning from abroad can constantly introduce the causal agents of malaria, which are microscopic protozoa in the genus Plasmodium spp.  On average, one person dies every 10 seconds as a result of a little mosquito “bite”.  In Canada hordes of mosquitoes can actually darken the sky - researchers were bitten about 9,000 times per minute; at that rate they could lose 1/2 their blood in 2 hours and die from blood loss!  But our primary reason for controlling mosquitoes usually is only to lessen the annoyance caused by their bites and then only secondarily to reduce the transmission of human and equine viral encephalitis and dog heartworm.  The annoyance caused by mosquito feeding can include the itching, restlessness, loss of sleep and nervous irritation in all people, pets and domestic animals that suffer from their attacks.  Mosquitoes do not really “bite”, but they penetrate their victim’s hide or skin with their proboscis or hollow, flexible snout.  The female has a pump in her head which she uses like a turkey baster to suck in your blood.  The average meal takes about 1 millionth of a gallon per bite.  Their saliva makes us itch.  Usually this minor annoyance can not be documented in terms of economic loss, but, obviously, there may be some major economic losses, e.g., decreased recreation income and lower milk and beef production due to blood loss and irritation.  Occasionally extremely large numbers of mosquitoes can actually cause the death of domestic animals through blood loss and anaphylactic shock from reactions to mass injections of mosquito saliva.  Mosquitoes are not strong flies- so fans easily blow them away.  The reproductive success of mosquitoes depends in a large part on the ability of gravid females to locate and select oviposition sites that will support the growth development of their offspring.  Enzymes diluted in water create an adverse environmental condition that renders the water repellant and/or lethal to all stages of growth.

Maintain tight screens and weather-stripping.  Use sodium vapor lamps or yellow non-attractive light bulbs at outside entrances.  Remove or empty frequently any containers that may hold rainwater (flower pots, tires, cans).  Clean out clogged roof gutters holding stagnant water.  As a last resort, add light-weight oil or diluted Kleen Kill® (Kleen'em Away Naturally™)  Enzyme Cleaner to surfaces of ponds, ditches and even animal hoof prints in mud where mosquitoes may breed.  Community effort is needed.  Try the proper, professional use of  entomopathogenic bacteria, e.g., Bacillus thurijngiensis strains (Bt) or Bacillus sphaericus (Neide) (Bs), another important pathogen of mosquitoes, diluted Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners, dehumidifiers and/or fans and other Intelligent Pest Management® controls before spraying any volatile, synthetic pesticide poisons.

Mosquito control agencies in the United States and Canada together send over $80 million annually using very dangerous synthetic pesticide poisons that kill or injure non-target species, e.g., people, pets and the beneficial creatures that feed on mosquitoes, to reduce simple mosquito annoyance.  They are wasting our money by attacking the adult populations which actually increase immediately after these toxins are sprayed.  Flight and biting activity increases over 500% on nights with a full moon.  (The Asian tiger mosquito, Aedes albopictus, is unusual in that it is active (biting) during the day- so bats, nighttime spraying and other nocturnal controls are not very effective.  Treat tires and other stagnant water with diluted enzymes.)  The mosquito’s amazing whine is caused by the sound of their wings fluttering up to 600 times a second.  A mosquito can sense a person 20 feet away.  In studies done on Sanibel Island, Florida, we consistently found the adult population the day before the pesticide poison bombing was actually less than the day after.  The reason is simple - the mosquitoes can replenish faster than the natural predators, e.g., dragonflies, fish, frogs, nematodes, giant water bugs, bats, spiders, birds, ants, backswimmers, snails, water scorpions and striders that feed on them can.  In addition, there are increases in tree pests because the adult mosquito pesticide poisons are broad spectrum killers that kill the organisms that keep help forest pest population under natural control. Dehumidifiers, BT’s, screens, fans, caulking and personal care can provide far better and, obviously, safer control.  In addition we still allow entire wildlife food chains to survive.  Proper Intelligent Pest Management® control includes the removal of all stagnant water, the wise use of repellents and proper clothing, the use of fans, and the development of natural predators.  Remove the cause rather than treat the symptom.  While mosquitoes remain a major killer in other parts of the world, in the United States, mosquitoes are simply not the scourge they once were.  But they’re still irritating, they still bite us and there are some species in the United States that may still spread disease.  Mosquitoes also serve a vital ecological function.  The larvae, pupae, and adults are important as food for fish, birds, bats, frogs, and insects— an essential consideration when the subject of mosquito control arises.  While there are more than 13 genera of mosquitoes in the United States, Most pest mosquitoes belong to one of  three:  Aedes, Culex, or Anopheles.  The one thing that all mosquitoes require to complete their life cycle is water.  If people could manage all standing water,  we would also manage all mosquitoes.  While we can fill in a puddle, we don’t want to fill in a salt marsh.  We can empty a bucket, but it’s not so easy to empty a tire dump.  Spray Kleen Kill® (Kleen'em Away Naturally™)  enzymes in stagnant water you can not empty or drain and you will control these pests, but remember you may also kill some beneficials.  Kleen Kill® (Kleen'em Away Naturally™)  enzymes are active virtually as long as they are wet.

ORDER - Diptera (The true flies.)

FAMILIES - Cuilicidae and Toxorhynchitinae

GENERA - Aedes, Anopheles. Culex, Culiseta, Masonia and Psorophora

(Note: Toxorhynchitinae female mosquitoes do not feed on blood like culicine female mosquitoes which do, and contain the bulk of mosquito genera.  There are about 3,500 species and subspecies and at least 34 genera worldwide.  Canada has at least 74 species and the United States has over 169 species belonging to 13 genera the most important genera include Aedes, Culex, Culiseta, Psorophora and Mansonia .  (Michigan has more than 60 species of mosquitoes; Texas has at least 83 species.)

TYPE METAMORPHOSIS - Complete

Egg -  Slender, oval, usually dark and visible to the naked eye.  Depending on the species, after each blood meal, females produce 50 - 500 eggs in the first brood and usually fewer number of eggs in the succeeding 8 - 10 broods.  The protein in animal blood produces the yolk in the fertilized eggs.  The egg-laying process can repeat itself every 3 days.  Anopheles eggs are laid singly; in the case of Culex mosquitoes they are laid in clusters (rafts) in the mud or on the surface of water or wherever water is likely to accumulate.  The mosquito eggs float until they are it is hatched in 2 - 6 days.  If optimum conditions persist for only a 2-month period, an initial population of 1,000 female mosquitoes can grow into millions.  For every mosquito adult biting people there may be at lease 300 eggs waiting to hatch.  Mosquito eggs can lie dormant for up to 7 years!

Larva - They have a large head and thorax; legless with slender abdomens and look “hairy”; up to 3/8" in length they are called “wigglers, wiggle tails or wrigglers” and can be found in still, slow moving water feeding on small organic debris, algae and microscopic life, e.g., protozoans.  Except for Anopheles larvae which rest horizontally on the surface of the water and breathe directly through a hole in their abdomen - the rest are in the water and a siphon tube on the abdomen is thrust into the air for oxygen. This stage usually takes 4 - 10 days  and can include 4 larval instars.  This is the most vulnerable stage to attack mosquitoes - they are concentrated in smaller areas.  They sometimes go cannibalistic and eat the smaller, newly hatched stages.  Larvae do not normally develop in water sources with a current, e.g., rivers and streams.

Pupa - Found in water, it has a large combined head and thorax and slender abdomen, giving it a comma shape.  Swims actively.  This stage usually takes 5 - 10 days.

Adult - Small and fragile, two winged with long, slender legs, capable of flying one to several miles. A mosquito can fly up to 300 miles in its lifetime.  Some mosquitoes won’t go more than 500 feet from the larval habitat - others can cover 6 - 8 miles a day with the help of the wind.  The female flies into a swarm of males and mating takes place almost immediately in midair.  Mating takes from 4 to 40 seconds and some stay together for over an hour.  The Asian tiger mosquito was carried in a pile of scrap tires from either Nagasaki or Kobe, Japan to Houston, Texas and now has spread to over 21 states.  Mosquitoes can only fly at 25 mph, but they can fly up, down, sideways and backwards.  Wings, legs and other body parts are more less covered with tiny scales.  Males have bushy feather-like antennae; females do not.  They smell with their antennae.  Can live from 10 - 60 days with females capable of living up to 5 months or more, depending on predator pressures.  Note: They cannot fly into the wind, so simply sit in the breeze or install a fan outside.  Throughout the mosquito’s lifetime it can bite up to 6 times - even more if a blood meal is interrupted.  Only female mosquitoes bite.  They can sip up to 1-1/2 times their own weight in blood and still fly away.  They can sense a person 20 feet away.  They are attracted by carbon dioxide, odor, heat, moisture and wind; activity peaks at down or dusk.  Male mosquitoes locate females by the sound of their wings in flight- the sounds range from 500-800 vibrations a second.  Males will come to any source (e.g., a tuning fork)  that produces these sounds.

TYPICAL MOUTHPARTS

Larva - Chewing.

Adult Female - Piercing, cutting and sucking.  Blood protein is needed to produce eggs.  If she gets too bloated with your blood to fly, she literally releases a little “piddle” from her bladder on  you.

Adult Male - Tube not fitted for piercing the skin; feeds only on flower nectar and fruit juices.  The male helps pollinate flowers.

DISEASE ASPECTS - Mosquito bites result in red swollen areas called wheals which itch severely. Some people are highly allergic to the proteins injected by mosquitoes and are ill for days.  They are vectors of malaria, yellow fever, dengue, canine heartworm and several  forms of filariasis and encephalitis.  Canine heartworm disease is a serious, deadly disease wherever mosquitoes are present.  Thousands of dogs each year just in Michigan become permanently debilitated or die from lung, heart or circulatory problems caused by heartworms.  Heartworms, the diameter of a tooth pick, can grow from 5" to 14" long. In advanced cases, 100 or more worms have been found in a single heart.

LENGTH OF LIFE CYCLE -  Varies among species and climatic conditions; usually about 2 - 9 weeks.

LIFE CYCLE-  Of the four life stages of the mosquito—egg, larva, pupa, and adult—the adult is the only stage that doesn’t exist in standing water.  Males live 1-2 weeks, but females can live up to 2 months.

The female mosquito lays her eggs on the water or, in the case of Aedes mosquitoes, above the water in areas that are sheltered from waves and with sufficient organic matter to feed the larvae.  Eggs laid on the water’s surface hatch in one to three days.  Eggs laid by Aedes mosquitoes above the water line remain dormant until they are flooded.

The mosquito larvae or “wigglers” that hatch must live in water to survive.  They float at the surface breathing through an air tube and filtering food material through their mouth brushes.  When disturbed, the mosquito larvae dive towards the bottom with a jerking motion.  The larval stage lasts from five days to several weeks depending on the species and on environmental conditions such as water temperature.

The mosquito larvae transform into pupae or “tumblers”.  Although the mosquito pupae don’t feed, they are quite active and may be seen breathing at the surface or bobbing through the water.  Inside the pupal skin, the adult mosquito is developing and will emerge in two to three days.  Mosquitoes pass the winter either in the egg stage or as adults.

FEEDING HABITS - Only the female mosquito sucks blood, which she needs to lay eggs, but she feeds on  plant nectar for energy.  Her mouthparts have 6 long hollow needles; through one of the needles she drips saliva into the wound to keep the blood from clotting as she sucks it up through the other hollow needles.  Adult male mosquitoes feed only on plant nectar and are harmless to people.

Most female mosquitoes feed during the last 2 hours of sunlight until just after dark and begin just again before daylight.  They spend the daylight hours hiding and resting in dark, damp, cool areas.  Some mosquito species, however, feed during the day and others feed during both day and night.

The mosquito’s blood-sucking habit is what causes certain species of mosquitoes to be disease vectors.  If a female mosquito sucks blood from a person infected with malaria, for instance, the disease organisms can survive and reproduce in the mosquito, ending up in her salivary glands.  When she next feeds on a host, she inoculates her new victim with the disease.

Larval mosquitoes feed on organic debris (with the exception of a few species that are predators).  They use a pair of mouth brushes to strain out small aquatic organisms and particles of plant and animal material present in the water.  Note: Kleen Kill® (Kleen'em Away Naturally™)  Enzyme Cleaners will “eat” the organic debris.

HABITAT - Mosquito eggs, larvae and pupae are found in undisturbed, slow moving or stagnant water.  Adults normally stay in protected, secluded places during the day.  They become active and bite late in the afternoon and during the early evening and morning hours when the wind is calm.  Mosquitoes are most prevalent in moist, wooded or lowland areas.  Eliminate water habitats and you control mosquitoes!

NATURE OF INJURY - Mosquitoes are persistent biters of all warm blooded animals and some cold-blooded creatures, e.g., frogs and snakes.  They individually consume about 2 - 8 milligrams of blood per meal.  Aside from irritating bites, a number of species transmit diseases and have caused allergic reactions and even death.  Aedes aegypti is worldwide in distribution; carries urban yellow fever and the only known vector of Dengue in the New World.  The malarial parasite carried by mosquitoes probably kills a million people in Africa each year.  Malaria claims 2-7 million lives throughout the world annually.  Mosquitoes also carry yellow fever and at least 100 different viruses - these diseases adversely affect at least 800 million people every year.  The Anopheles mosquito, for instance, carries malaria, and several species including Culex, the common house mosquito that stings before she bites, transport encephalitis-causing viruses.  You can sample/collect with biting or landing counts.

Seasonal Abundance.  Mosquitoes may breed and develop any time from the beginning of spring to the first hard frost of fall.  In general, populations are highest in summer and early fall.  There may be from one to several generations of mosquitoes during a season depending on the species, the temperature, and the amount of rainfall.

When rainfall is abundant, many mosquito species can lay eggs continuously.  Under ideal conditions with high temperatures, development can be completed in less than a week, resulting in large populations of flying adults.  We do not suggest you use DEET, not only do we believe this product is dangerous - the repellent only works after the mosquito lands on treated skin, it gets confused and forgets what they were going to do and fly away - if you forget a patch of skin they will find it right away.

Medical Importance.  Worldwide, mosquitoes transmit many debilitating and fatal diseases, especially in tropical, developing countries.  The most important of these is malaria, which has been on the increase in the last decade.  The Centers for Disease Control and Prevention and the World Health Organization both report that currently available treatments for yellow fever and malaria are failing.  In the United States, most mosquitoes are primarily an annoyance, causing itching bites and welts that can become secondarily infected.  Human mosquito-transmitted diseases remain relatively rare, due largely to modern pest control methods and disease detection.  Encephalitis, among humans, and dog heartworm, among dogs, are the main diseases transmitted by mosquitoes in the United States.  Pregnant women attract mosquito attacks more than anyone.

Malaria.  As mosquitoes become more and more resistant to insecticides each year, new control strategies are sorely needed.  Researchers at the Johns Hopkins School of Public Health have identified a protein in the salivary glands of the female Anopheles gambiae mosquito - the primary carrier in Africa - that appears to help Plasmodium recognize and gain entrance to that mosquito’s salivary gland.  The Author believes that his patent pending use of protease enzymes will help destroy this protein.

Encephalitis.  At least six types of mosquito-transmitted encephalitis occur in the United States.  These are Eastern equine encephalitis, Western equine encephalitis, California encephalitis, St. Louis encephalitis, Venezuelan equine encephalitis, and La Crosse encephalitis.  Each type is caused by a different virus or virus complex affecting the central nervous system.  Symptoms of EEE in horses include fever, impaired vision, irregular gait, reduced reflexes, inability to swallow, convulsion and death.  These viruses are normally transmitted by mosquitoes from birds or small mammals.  Occasionally horses or humans are infected.  Despite the small number of people infected annually by eastern equine encephalitis, it is considered a serious disease because it is often fatal.  Vaccinating horses properly will prevent them from contracting Eastern equine encephalitis.

Dog heartworm.  This is a filarial parasitic disease transmitted by a number of different mosquitoes to dogs and, rarely, man.  Once a problem only in the U. S. coastal areas, dog heartworm is now found in every state in the United States.  The nematodes, which lodge and grow in the heart tissue, can be fatal to dogs if left untreated.

There has been some concern about whether mosquitoes are capable of transmitting AIDS from an infected person to an uninfected person. Unlike encephalitis viruses and other mosquito-transmitted (viral) diseases, the HIV virus that causes AIDS is supposedly not able to survive inside the body of the mosquito.  However, the American cockroach and ticks in Africa have already been implicated in the spread of HIV.

MONITORING AND THRESHOLDS

Introduction

Mosquito sampling and counting the mosquito population accomplishes a number of things.  It helps determine whether mosquito control is necessary.  It determines what growth stage the mosquitoes are in, providing information necessary to properly time control methods.  It tells which mosquito species are present, especially important in areas of disease outbreaks.  Finally, it helps to gauge how effective control efforts have been and when they need to be employed again.

Mosquito sampling should be done at least once a week, and more often during peak season.  It is important to consistently sample the same sites each time.  The numbers counted, the growth stage, and the species and sex should be needed when possible.  All of this information gives an estimate of the population and must be compared with previous counts to determine whether the number of mosquitoes are increasing or decreasing.  You can make an estimate of the number of mosquitoes in an area by counts of larvae or adults or both.

Larval Dipper Counts

Mosquito larval dippers can be purchased through biological supply houses or you can make your own.  It is basically a shallow, plastic, enamel, or aluminum cup attached to a long handle.  To collect floating mosquito larvae, pupae, depress one end of the dipper under the surface and quickly but smoothly scoop up larvae.  If you move too quickly or cast a shadow over the surface, they will dive to the bottom.  The number of dips at each site will vary according to the size of the water body, but generally are in multiples of ten.  Take five dips from open water and five from the water’s edge, near vegetation if possible.  Dipper instructions should be made weekly during breeding season.  Larvae can also breed in rainwater that has collected in containers such as eavestroughs, toys, buckets, garbage cans, canoes, tires, and animal watering troughs.  To sample larvae in less accessible areas such as tree holes, use a large basting syringe to collect them.  Empty them into a white pan for counting to mosquito larvae.  One advantage to sampling larvae is that the problem can be treated with Kleen Kill® (Kleen'em Away Naturally™)  enzymes at the same time it is identified.  When counting adult mosquitoes, the mosquitoes can be flying in from some distance away.

Adult Trapping

Trapping of adult mosquitoes gives information on the relative population size and the species composition.  Light traps are very helpful for monitoring certain species of mosquitoes.  Not all mosquito species are attracted to lights, e.g., Anopheles and Aedes.  Different models of traps vary in the numbers, the species, and the proportion of males to females that they each attract and catch.  New Jersey light traps with a frosted 25 watt bulb and CDC light traps (and their variations) are the traps most commonly used.  Light traps are operated from dusk to dawn, powered either by electric line or a battery.  Some traps are available with a photoelectric cell that turns the light on at dusk and off at dawn.  When mosquitoes approach the light, they are blown by a small fan down through a funnel into a killing bag or jar.  The light mosquito trap should be hung about 6' off the ground in an open area near trees or shrubs but away from competing lights and buildings.  Traps should be emptied each morning and the catch stored in a labeled box until it can be sorted and identified.

Since mosquitoes are attracted to carbon dioxide in the host’s breath, some light traps are augmented with a one pound block of dry ice, wrapped in newspaper and hung next to the trap.  The addition of dry ice also allows sampling on moonlit nights or in areas where bright lights may conflict with the light trap.  And it allows daytime sampling of species that are active during the day or that are not attracted to lights.  Other traps include sweep nets and large drop nets of various designs.

Because some mosquito species are not attracted to light traps they should be used in conjunction with other kinds of sampling methods.  Monitoring for adult mosquitoes is an important part of the management of some mosquito-vectored diseases such as eastern equine encephalitis.  The decision to use pesticides for mosquito suppression should be made only after intensive monitoring of the mosquito population in an area to determine if the species that actually vectors the disease to humans or horses is present.  The incidence of the disease in the wild animal population (or in caged chickens) is monitored as a way to estimate the possibility of transmission to humans or horses. Education is also emphasized to alert people to the presence of the disease and how to go about protecting themselves.

Resting Stations

Adults of many species are inactive during the day and rest quietly in cool, dark and damp places.  Daytime collections made at these sites give a good indication of the species of mosquitoes present in the area.

Adult Landing/Biting Counts

Collecting mosquitoes as they land on you or an animal to bite is a convenient method of sampling biting populations.  It simply involves rolling up a sleeve or pants leg or exposing your back and sitting quietly for a designated period of time, usually 10 minutes.  During that time, each mosquito that lands on the leg or arm or back is collected with a battery or mouth-operated aspirator.  It is important that you collect each landing mosquito for counting and identification and to ensure that you don’t count the same individual again.  Mosquito biting counts are best conducted from 30 minutes before sunset to 30 minutes after sunset (unless sampling day-biting species) by the same person each time.

The advantage to using landing counts as a mosquito sampling device is that you are counting only the biting (female) mosquitoes.  The method does not collect male mosquitoes or species that do not actively bite people.  It can also be used to count and collect daytime biters.

When sampling adult mosquitoes, sample any and all areas where mosquitoes may be a nuisance.  Obviously, you should sample areas from which you have received complaints and near areas with high larval or pupal counts.  Sample the same sites regularly, from one to seven nights a week.  Adult mosquito information is most useful in gauging the extent of your mosquito problem, since it is only the adults which transmit disease or create a nuisance.

Threshold/Action Population Level

The data from mosquito sampling and monitoring will be used to help decide at which mosquito infestation level to initiate management tactics.  This decision level may be based on larval and/or adult counts, mosquito complaints from visitors, residents, students, patients, etc. the potential for disease outbreaks, and the risk of the management tactics to other animals.  For instance, in an area where there have been actual reported encephalitis cases, the risk is higher and the action level will, obviously, be lower than in other cases.

The number and location of mosquito complaints should be plotted on a graph against the counts of immatures adults for the same date and site.   The amount of unacceptable complaints is the injury level.  The graph should show the number of mosquitoes that correspond to the complaint injury level.  This is your action level.

Action levels will, obviously, be different for each situation.  In some areas, general annoyance does not occur until the number of female mosquitoes caught in light traps exceeds 25 per night.  Other action levels that have been used are landing rates averaging more than 5 mosquitoes in 10 minutes and dipper counts averaging 5 larvae per dip or the outbreak of disease.

HARBORAGE POINTS - Young mosquito stages breed in any available water.  Mosquitoes may be found in birdbaths, blocked rain gutters, rain barrels, buckets, old tires, bottles, dishes, tin cans, jars, cisterns, watering cans, toys, carts, hollow stumps or trees, plastic wading pools, septic tanks, air conditioner drain outlets, utility meters, wheelbarrows, ponds, over irrigated lawns, cesspools, watering troughs, drainage ditches, mud puddles, flower vases, potted plant saucers, unused toilets,  hoof prints, water softening tanks, wells, on flat roofs and any other place where undisturbed or stagnant  water can collect.  At night, like vampires, the adults emerge from breeding sites and fly to areas of human and animal habitation to obtain blood.  During the day most adults remain secluded in such places as trees, outbuildings, shrubbery, cars and homes.  Eliminate cool, dark, damp areas.  Wash/fog/spray infested areas with diluted Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners.

INTELLIGENT PEST MANAGEMENT® CONTROL - First of all, identify the pest mosquito species then establish a quantity tolerance or acceptable injury levels.  Remember to keep all screens in good repair.  Mosquitoes have become resistant to many insecticide poisons.  Cover all flues and chimneys, especially during the summer months.  Eliminate resting places such as tall grass, weeds, shrubbery and vines from around the buildings.  Eliminate rainwater-collecting items such as old tires, pans, cans, buckets, etc.  Never kill any dragonflies or damselflies who both eat lots of mosquito larvae and adults.  At least once a week, drain or treat plastic swimming pools and birdbaths.  Provide for proper water drainage around the foundation of the building.  When visiting mosquito-infested areas, wear protective clothing to prevent bites.  If small garden ponds are present, use fish (Gambusia sp. or others), or treat ponds with Bacillus thuringiensis israeliensis or Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners as a safe and effective alternative.

The key factor in a mosquito intelligent pest management® program is determining whether or not control is necessary.  This decision requires a regular mosquito sampling program to determine what species are present and in what numbers, and a set of action thresholds to determine if management tactics are necessary.  If control is needed, then decisions have to be made on the best combination of tactics to suppress the mosquito population while affecting the environment as little as possible.  You can always swat them, but often you create a breeze with your intended blow that blows them away.  If you lightly pinch your skin  on either side, the pressure will trap her stinger inside and even when her sensors tell her to stop, she’ll continue to take in blood until she literally explodes.

Normally, source reduction—eliminating or altering the water so that the mosquitoes cannot breed or complete their life cycle—is the first choice for control.  If source reduction is impossible or incomplete, the next tactic to consider should be biological control of the larvae with predators, bacterial insecticides, or growth regulators.  Measures that increase water circulation like the Clean-Flo® system and vegetation removal or altering water circulation patterns may reduce mosquito breeding.  Interpretive displays (education) can be used to explain the role of mosquitoes as a food source for animals such as bats, birds, fish, and to help people understand that not all mosquitoes bite or carry disease and so all mosquitoes do not need to be killed.  Personal protection through the use of proper clothing and mosquito repellents and fans can be explained, as well as the avoidance of areas with high mosquito populations.

Source Reduction

The simple fact that all mosquito species require water and aquatic vegetation to develop is the obvious key to their control.  No standing water means no mosquitoes.  Aquatic vegetation offers mosquito larvae and pupae protection form wave action and natural predators.  Source reduction is the first step in an intelligent pest management® program for mosquitoes.  It is simply the use of mechanical methods to eliminate standing water.  Source reduction involves filling, deepening, draining, ditching, managing water levels, maintaining shorelines, managing aquatic and inundated vegetation, and others.  While these methods may prove to be more extensive and more expensive than some other controls, in most cases they need be done only once.  Unfortunately, these methods will most likely require permitting from several agencies before they can be implemented.  They are also not feasible in natural zones.  Look in the water to see the “wigglers” (larvae) and “tumblers” (pupae) that indicate mosquitoes are breeding in the water then add Kleen Kill® (Kleen'em Away Naturally™)  enzymes or Not Nice to Bugs® and see your mosquito population in or out of the water disappear.

Source reduction controls the immature mosquito stages—eggs, larvae and pupae.  Because these stages are concentrated in discreet bodies of water, they are much easier to control than are dispersed adult mosquitoes.  Two water management tactics are ditching and ponding.  That these would only be allowed in a developed zone.  Ditching controls mosquitoes in two ways.  In some cases water drains out of the potential breeding sites.  In others, ditching allows fish access to the isolated pools where they prey upon the larvae and pupae.  Ponding is another water management tactic that turns a temporary pool breeding mosquitoes into a permanent one capable of supporting fish and other mosquito predators.  Ponding is accomplished by raising water level, digging new pools, or through impoundment.

If standing water can’t be completely eliminated, control of mosquito larvae in the water is the next step.  This is best done with natural controls such as mosquitofish or biorational insecticides.  The latter do not affect pupae and should not be used if this is the predominant life stage.  You can use Kleen Kill® (Kleen'em Away Naturally™)  enzymes at any stage to gain immediate control.

Tips On Eliminating Mosquito Breeding Sites On Your Property.

The objective is to eliminates all water sites where mosquitoes can breed.  Remember, some species of mosquitoes can breed in as little as one-half inch of standing water.

Some mosquitoes can hatch in as little as one week.  Where drinking water must be made available-as for pets and other animals-it is necessary to change the water and flush out the container at least once a week to disrupt the breeding cycle of mosquitoes.

Following is a list of things you can do to try to reduce mosquito breeding grounds on your property.

Empedocles, a physician and philosopher in the mid-fifth century B.C., is credited with draining marshes and running two rivers together through the town of Selinunte; thus he prevented the water from becoming a breeding ground for mosquitoes.  He also broke a gap in the rock wall behind his native town of Agrigentum so the “healthy north wind could blow the fever-bearing vapors (and mosquitoes) of the plain far our to sea.”  In 1909 Brazilian rubber plantations paid workers to smoke II Negro Mortes or “the black cigars of death” on the verandas of their mansions.  These lethal cigars were made of tobacco, chemicals and petroleum tar; the fumes were effective, but it is estimated one smoker died for every 5 billion mosquitoes that were killed.

Diet for Mosquitoes?  University of Florida scientist, Don Borovsky, is quite willing to share his recipe to control mosquito populations.

First, take 100,000 mosquito ovaries, dried and crushed into a powder that contains their digestive control hormone (see Bug Juice). From the nearest pool or pond, scrape off the green scum, also known as chlorella, an algae.  Insert the hormone into the chlorella, make it into a pill, then place the pill into any water body where mosquitoes are known to breed.  Then watch the larvae feast on the chlorella.  Famine follows.

Borovsky said when he first pulled out mosquito ovaries, homogenized them and inserted them back into mosquitoes, he found that the mosquitoes produced no more eggs.

“So at first we thought we had a birth control pill,” Borovsky said.  “But then we found that the reason they were not producing eggs was because they were not digesting, so then we knew we had a diet pill, not a birth control pill.”

“Fortunately, now we can synthesize the hormone, so we don’t have to use 100,000 ovaries for each batch anymore,” Borovsky said.

The synthesized hormone is inexpensive, as is chlorella, which is found and produced worldwide.  Chlorella, in fact, turns out to be the perfect ride for the mosquito hormone, because it can be freeze-dried and stored for long periods and then brought back to life as the deadly diet pill.

“This is a natural bullet that we can use in the environment because the hormone doesn’t stay in the environment,” Borovsky said.  “The chlorella stops producing the hormone within three weeks.”

That’s by design, Borovsky said.  If the hormone were incorporated into the chlorella genome and chlorella continued to produce the hormone, making it omnipresent in the environment, mosquitoes could become resistant to it.  But the hormone sits outside the genome and, after the third division of the chlorella, it no longer can be detected.

Of course, Borovsky points, it mosquitoes become resistant to their own reproductive hormone, that could have unknown adverse consequences for them as well.  “We have to stay a step ahead of them or outsmart them all over again,” Borovsky said.

Natural Enemies

Mosquito larvae are an important food for many aquatic organisms.  Large numbers fall prey to phantom gnats, damselflies, dragonflies, fish, shrimp, other water insects, and spiders.  Naturally occurring bacteria, protozoa, snails, fungi, and nematodes also kill mosquito larvae.  Both bacteria and predatory fish have been used as biocontrol agents to control mosquito larvae.  Adult mosquitoes are also fed upon by birds, bats, frogs, lizards, spiders and insects out of the water environment.  Dragonflies have eyes with as many as 28,000 facets and can spot a mosquito 25 feet away and fly at a speed of 60 mph.

Mechanical Controls

Screening of doors, windows, and vents is a time-honored method of keeping mosquitoes out of structures.  Ordinary window screen of 16x16 or 14x18 meshes to the inch will keep out most mosquitoes.  Campers can use fans and/or hang mosquito netting over cots, tent openings, picnic tables, etc.  Long sleeves, long pants, hats, and veils give additional protection from mosquitoes.

“Bug zappers” and ultrasonic devices have not been proven to be effective in controlling mosquitoes and other noxious flying insects.  Try to reduce the population by fogging with enzyme cleaners.  Generally, mosquito control is best undertaken on an area wide basis by public health agencies  or mosquito abatement districts.  We only recommend they use the bacterium Bacillus thuringlensis israeliensis because it is relatively safe and environmentally sound.  Bti is highly selective, killing only mosquitoes and several other water inhabiting insects.  First try fogging with Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners or Kleen Kill® (Kleen'em Away Naturally™)  peppermint soaps with enzymes or simply dish soap and water.

How Bti Works to Control Mosquitoes

The bacterium Bacillus thuringiensis israelensis infects and kills mosquito larvae.  It is relatively safe and environmentally sound because it is highly selective, killing only mosquitoes and certain related water-

inhabiting insects.  The larvae feed on Bti spores and crystals suspended in the water.  Within 10 minutes the spores and crystals enter the gut of the larva and the crystals dissolve.  Within 1 - 4 hours the gut wall of the larvae break down from the action of these toxic crystals.  Then, within 2 - 12 hours after the crystals have done their work, the spores escape into the larvae’s body cavity and the larvae die.  Note:  There have been increased reports of low-level resistances to both Bt strains and Bs.

NON-TOXIC MOSQUITO CONTROL

PREFORMED ENZYME CLEANERS - Kleen Kill® (Kleen'em Away Naturally™)  preformed enzyme cleaners are organic, enzymatic, bio-catalytic agents which have proven to be outstandingly effective for mosquito larva and pupae control.  Kleen Kill® (Kleen'em Away Naturally™)  preformed enzymes  ALTER THE SURFACE TENSION OF WATER SO THAT LARVAE AND PUPAE HAVE DIFFICULTY MAKING CONTACT WITH THE AIR ABOVE THE WATER SURFACE film.  Adult mosquitoes can not maintain surface contact on water treated with preformed enzymes.  Late winter treatment of potential breeding water will preclude breeding.  Other insects, as well as leaves, etc., do not remain on surface of water treated with preformed enzymes, but sink below the surface.

It is interesting to note that the pupal stage is the most quickly affected by preformed enzymes, whereas larvae tend to persist for longer periods both in field and laboratory experience. The opposite is found to be the case in the use of insecticide poisons, where the larval stage is the one most quickly killed.  In stagnant water, large pounds, bird bathes, etc. you will note ultra-active response of the aquatic organisms upon initial addition of performed enzymes, as siphon tubes can no longer make contact with outside air. Kleen Kill® (Kleen'em Away Naturally™)  preformed enzymes last indefinitely in still or recirculated water.  In many instances 100% control has been achieved.  It is less effective and has less residual effect in moving water or in a pond with both inlets and outlets.

Water treated with Kleen Kill® (Kleen'em Away Naturally™)  preformed enzymes or Not Nice to Bugs® is harmless to fish life or animals and pets.  It is non-irritant to the most sensitive skin tissue and, if accidentally taken internally, would produce only a mild laxative effect comparable to bland soaps.

Kleen Kill® (Kleen'em Away Naturally™)  enzyme concentrate can be applied as a spray or dripped into an inlet source; concentrates are instantly soluble in water.  Application should result on a final tank or pond solution of 1 part concentrate to 50,000 parts water.  Dilution for application is best made at a rate of 1 part concentrate to 1000 parts water, but stronger solutions may be used.  Check dilution rates - older or “improved” concentrates may change dilutions.

Muck and Organic Sediment Removal: Kleen Kill® (Kleen'em Away Naturally™)  preformed enzymes and/or other bacteria, especially when combined with Get Set’s lake, pond and sewage aeration/inversion systems, really can digest bottom debris, muck and other organic sediment, but the Kleen Kill® (Kleen'em Away Naturally™)  enzymes should be applied at greater concentrations, e.g., 1 part concentrate to 25,000 parts water initially.

NOTE:  Kleen Kill® (Kleen'em Away Naturally™)  Enzyme Cleaners by Ginesis Products, 1-800-492-4818 are not registered for use as a pesticide by the EPA; the above information was obtained in field tests by independent parties using Kleen Kill® (Kleen'em Away Naturally™)  preformed enzyme cleaners and listed for informational/educational purposes only - we only note their potential for use in safe, effective mosquito control.

OTHER WAYS to Control Mosquitoes

Altosid® or methoprene induces damaging morphological changes in the second, third and fourth instars of mosquito larvae, resulting in the failure of adult mosquitoes to emerge from pupae.  Timing is very important because only mature larvae are effected.  Impregnated on sand or packaged in slow-release briquettes, this IGR  is effective for 30 days in standing water.  It can be also applied as a spray solution from the air or ground.  We also highly recommend the use of predatory mosquito larvae (Toxorhychites spp.), the mermethid or mosquito-attacking nematode, Romanomermis culcivorax and/or the mosquito-eating fish, Gambusa affinis, killfish (fundulidae), minnows (cyprinidae), and/or tilapia and or guppies, e.g., Legister reliculatus wherever possible.   The killfishes (Fundulus) in salt water and the top minnows (Gambusia, Labistes, and Panchax) in fresh water are most useful.  The effective use of any chemical control depends on species of mosquitoes, the area of country, the time of year and many other factors.  It is very difficult to obtain satisfactory control of night flying mosquitoes by treating even very large areas with synthetic pesticide poisons, so never try a “spot” application.  Mosquitoes are attracted to carbon dioxide, so use dry ice traps.  Avoid exercising outside, especially at dusk, when they are most voracious.  However, there are some methods which will reduce a mosquito problem on an individual structure basis.  Kleen Kill® (Kleen'em Away Naturally™)  enzymes and/or Not Nice to Bugs® quickly kill all stages of all species and remain active as long as they are wet- so use with caution.

INTELLIGENT PEST MANAGEMENT® CONTROL OVERVIEW

A.  First correctly identify the adult species.  Use a gravid or light trap for monitoring adult mosquitoes.   The Centers for Disease Control have standardized the design of light traps used for mosquito monitoring.   Such traps cannot be used for mosquito control; however, because their capacity is too limited. Mosqui-   toes are attracted to the light or dry ice, enter the trap and are then blown downward by a small fan into a  mesh bag, from which they cannot escape.

B.   Establish tolerance, annoyance, action or injury levels.  Find and note the larval source of all the biting   adult species.  Eliminate the larval sources if at all possible by draining and/or filling them in.  Installbat and/or purple martin houses outside.  Use other biological controls/predators/fans.

C.   Inspect the premises thoroughly for standing water and other breeding sites.  All receptacles in which  water can accumulate should be routinely emptied, filled in and/or and destroyed if possible.  Plumbingleaks which are causing puddles should be repaired.  Bird baths, watering troughs and other water storage   points which cannot be treated with Kleen Kill® (Kleen'em Away Naturally™)  enzymes should be emptied and cleaned at least once a week.  Fog inside and outside with Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners and/or peppermint soaps.  Fill in all holes or burrows in the ground, stumps, trees, etc..

D.   Permanent standing water, such as ponds, streams, swamps, and drainage ditches, may be treated to control mosquito breeding by using IGR’s like methoprene, marketed as Altosid by Zoecon,  Bti, or by goldfish, tilapia, nematodes, guppies (Poecillia reticulata) or the like.  Where injury to vegetation is not a  problem, oil base sprays may be applied lightly to cover the water surface.  These should be applied atweekly intervals during the mosquito season.  Do not use poisons to treat garden fish ponds or any water which will be used or consumed by humans or animals.  Prevent breeding situations by regularemptying and cleaning with Kleen Kill® (Kleen'em Away Naturally™)  enzymes or by screening and caulking.

E.   Buildings and homes which are constantly invaded by mosquitoes usually have defective, missing screening.  All screens on windows and doors should be inspected, repaired and tightened.  Sixteento 18 mesh screening should be used to prevent mosquito entry.  Be sure to also thoroughly caulk all  holes, cracks, crevices and other openings which may also allow entry.

F.   Mosquitoes inside a finished building can be temporarily controlled by Kleen Kill® (Kleen'em Away Naturally™)  enzyme sprays or vacuums and permanently by eliminating standing water accumulations.  It should never be necessary   to apply long-term synthetic pesticide poisons in buildings with proper screening.

G.   For personal protection on outside, protective clothing is always your best defense; try using fans  and soybean oil/or cedar oil, Skin-So-Soft® by Avon, oils of citrosa, coconut, birch, Lantana camara  (Linnaeus), Tarchonantus camphoratus essential oil, neem, blue stem grass, rosemary, yarrow,   spearmint, menthol, crushed citrosa or lemon thyme leaves, oils of sweet basil, citronella, cedarwood,  lemongrass, peppermint or eucalyptus, electronic repellers and if all else fails, a  combination of these.   Applied to exposed skin, sleeves and trouser cuffs, garlic repellents can prevent mosquito bites for severalhours.  If you are not allergic, try Ultra Muskol®.  I have had good results with some electronic mosquito repellers, but others have had no effect.  Caution:  The effective ones (that really sound like dragonflies)may attract bats at night.  Buzz Away by Quantum is a non-toxic, outdoor protection formula of naturalethyl alcohol from plants, plus essential oils of  citronella, cedarwood, lemon grass, peppermint and  eucalyptus or use Kleen Kill® (Kleen'em Away Naturally™)  peppermint and/or eucalyptus soaps, Kiss Off! from Kiss My Face contains   citronella oil and Rhodinol (from grasses grown in Sri Lanka) and Terpineol (from pine trees) along with moisturizers and botanicals.  Menthol will repel some ticks, so try it on mosquitoes, citronella candles oftendraw mosquitoes into the flame.  Don’t forget to simply vacuum them up - use fans. Avoid using   sweet scents and avoid cool, moist places, especially at   dawn or dusk.

H.   Adult mosquito control outdoors is accomplished by using fans... mosquitoes are not  very strong fliers and will not bother you in the wind. Wear light colors and prints.  Bathe regularly with pepper-  mint or unfragranced soap.  Mow the lawn regularly.  Mist with Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners or Kleen Kill® peppermint or garlic or eucalyptus oil or soaps.  Trim trees/shrubs.

I.    Cover the top of rain barrels with a fine screen 14-18 wires per inch - rain water can pass through but   mosquitoes can not.  Put in some fathead minnows if you can not screen.

J.   Plant scented geraniums or citrosa plants, lemon thyme, citronella grass, common marigold,  tomato, eucalyptus, sweet basil, and/or sassafras by gardens, walks, doors, windows, decks, pools   and patios to help repel mosquitoes.  Note:  Most plants release significant amounts of repellent oils only when their leaves are crushed.  Rub crushed leaves on a small portion of your skin to see if you get an allergic reaction before treating” your whole body or pet.  Florida residents have been spotted wearing  Bounce® fabric softener sheets on their belts or sticking out of their pockets to repel mosquitoes.

K.   Beneficial Organisms such as bats, praying mantis, toads, birds, dragonflies, fish should be enticed   or introduced into the area with houses and/or releases to permanently control these serious pests by   natural predation.  Mosquitoes are a key source of food for many species of amphipods (freshwater  shrimp) ants, backswimmers, bacteria, bats, birds, crabs, dragonflies, fish, frogs, toads, fungi, giantwaterbugs, ground beetles, hydra, mites, insectivore plants, parasitic nematocles, predacious snails and  spiders.  A mouse-eared bat can eat 600 mosquitoes per hour.  A large dragonfly can eat up to 100 mosquitoes in one forage at speeds up to 30 mph or more.

L.   Candles - Mosquitoes are drawn to carbon dioxide/light and are killed by the flame.  Citronellacandles are said to repel mosquitoes, but never burn them inside; the fumes are also harmful to your health.

M.  Non-toxic (permanent) mosquito control - Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners and/or Kleen Kill® (Kleen'em Away Naturally™)  peppermint  soap with enzymes have both proven to be extremely effective in field tests for mosquito larvae and pupae control.  They alter the surface tension of water so that larvae and pupae have difficulty making contact with the air above the water surface film.  Adult mosquitoes cannot maintain surface contact on water   treated with Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners.  Late winter treatment of potential breeding waters willeven preclude breeding.  Other insects, as well as leaves, etc. do not remain on surface of water treated   with  Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners, but sink below the surface.  It is interesting to note that the pupal stage is the most quickly affected by Kleen Kill® (Kleen'em Away Naturally™)  Enzyme Cleaners or Not Nice to Bugs®, whereas   larvae tend to persist for longer periods both in field and laboratory experience.  The opposite is found tobe the case in the use of insecticides, where the larval stage is the one most quickly killed.  In stagnant   water, large ponds, baths, etc., you will note ultra-active erratic response of the aquatic organisms uponinitial addition of Kleen Kill® (Kleen'em Away Naturally™)  enzymes, as siphon tubes can no longer make contact with outside air.  The active ingredient, the preformed enzymes, last indefinitely in still or recirculated water.  In many instances100% control has been achieved.  They both are less effective and have less residual effect in movingwater or in a pond with both inlets and outlets.  Directions:  Both can be applied as a spray or dripped into  an inlet source.  They are both instantly soluble in water.  Application should result in a final pond or tank  or pond solution of one part of either commercial product to 50,000 parts water.  Dilution for application is best made at the rate of one part of commercial preformed Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaner to 1000 parts water, but stronger solutions may be used.  Be careful; control may be virtually permanent!

N.   Resist going on a swatting rampage when biting insects start hovering overhead.  Studies indicate such movement can double the number of mosquitoes attracted to you.

O.   French radio station FUGUE FM broadcasts an electronic impulse at 16KHz to repel mosquitoes.

P.   In 1952, Penfold and F.R. Morrson in Australia found the most effective repellent oils against mosquitoes,march flies and sand flies were the oil of Huon pine wood (Dacrydium franklini) and leaf oils from  Backhousia myrtifolia, Melaleuca bracteata and Zieria smithii.

Q.   Mosquitoes in your room?  Turn off the lights and let them settle on the ceiling (or wall), then flip on the lights and vacuum them up.  Sleep in the breeze of a fan inside or outside.

Deet Note:  In the U. S. alone 50 to 100 million units of insect repellant are sold each year.  The New York Department of Environmental Conservation (NYDEC) banned insect repellents containing more than 30% DEET.  Florida health officials note some serious reactions involving children (including a few deaths) have been reported that may have been linked to this repellent (that melts plastic) and recommend that products containing DEET should not be used on children age 5 and under.  So use DEET only with great caution.  DEET can cause eye and sinus irritation, headaches, insomnia, confusion, etc.  Never use DEET on someone with open wounds.  DEET can dissolve nylon and plastic.

Natural Floodwater and Salt Marsh Mosquito Control - You can prevent these pests by maintaining high water over the annual floodplain during the  mosquito’s oviposition season.  Salt marsh mosquitoes, e.g., Aedes taeniorhynchus and Aedes sollicitans and floodwater mosquitoes, e.g., Aedes vexans and Aedes sticticus need soil on which to lay their eggs, and if the area is continuously flooded during this period, they cannot complete their life cycle.  If you can not flood, use mosquito fish, Gambusia affinnis, Kleen Kill® (Kleen'em Away Naturally™)  Enzyme Cleaners, garlic, methoprene and/or an effective Bti product or the new Bacillus sphaericus.

Overall Control Summary - Try planting scented geraniums (mosquito control plants) near entrances and other openings; rub your skin with the crushed leaves; these plants also make the bathroom smell nice, or try cedar oil and/or fabric softener sheets.  Adult female mosquitoes the only ones which bite, can irritate and annoy humans and our pets, and can transfer such diseases as malaria, encephalitis and dog heartworm.  Communities nationwide thus have intensive control programs for these pests.  Sadly, many programs unnecessarily rely solely on spraying potentially hazardous adult-killing pesticides (adulticides).  Mosquitoes develop resistance to all chemical pesticides over time, which renders the volatile, “registered” poisons ineffective.  Adulticides, such as the highly toxic organophosphate chlorpyrifos (Dursban™), present considerable risk to all living things, and kill beneficial insects and other non-target organisms.  Natural mosquito predators such as dragonflies, damselflies and beetles are killed by adulticides and take longer to come back.  (Dr. Wald from Libertyville, Illinois may have started the “rumor” that a purple martin can eat 6,600 mosquitoes a day.  Dr. Wald sold aluminum purple martin birdhouses.)  According to the President of the American Mosquito Control Association (AMCA), excessive spraying may exacerbate and even create mosquito problems by eliminating natural predators.  Sensible control strategies involve reduction of breeding sites, which provides long-term restraints on mosquito populations, and controlling the mosquito during aquatic states before they mature and have a chance to reproduce, transfer disease and annoy.  Bug zapping lights can attract more pests into a yard than they kill, and do not reduce the numbers of mosquito bites.  Volatile oils and perfumes, such as Skin-so-Soft and cedarwood, can repel insects but wear off rapidly so must be applied repeatedly.  Use fans to cover localized areas to harmlessly remove mosquitoes.  Habitat reduction measures can often be simple and can provide long-term effectiveness.  Install bat houses to encourage these mosquito feeders to establish residence.  Enhancing drainage of flood canals, irrigation ditches and fields; keeping street gutters and catch basins free of debris and flowing properly; enhancing drainage, or creating permanent deep pools in marshes, and the elimination of other large and small breeding habitats, e.g., cans, tires, bird baths, plugged rain gutters, etc., all are good preventative measures.  Tracking larval and adult population numbers, species types and breeding locations provides invaluable information used for determining when, where and what control measures might be needed.  Larvaciding allows effective control for mosquitoes at the source before they become a nuisance and can be done with biological control techniques.  Mosquito fish of the Gambusia genus are distributed by the thousands nationwide.  Only indigenous species should be used.  Be aware that they have occasionally triggered algal blooms after consuming algae eating organisms.  Bti (bacillus thuringiensis var. israelenis), one of the most popular and effective least-toxic biological controls, is a bacterial strain which, when sprayed into larval pools, is ingested by feeding larvae and kills them, or try Bacillus sphaevicus.  Oils kill via mechanical means by coating water surfaces which suffocates all stages of mosquito larvae and mosquito pupae.  Arosurf MSF® is a very thin vegetable-based oil that not only kills larvae but sinks egg rafts and adults on the surface by changing the water tension.  It is registered for application into potable water, is applied at rates of only .2 to .5 gallons per acre, and biodegrades in three to ten days.  Unfortunately oils can kill non-target organisms, including some predators, which similarly breathe from the surface.  Golden Bear Oil® is another popular larvacide.  It is petroleum-based oil which, while purer than more traditional diesel oils, persists and affects non-target organisms.  Methoprene is an insect growth regulator supposedly of low toxicity to mammals that disrupts normal growth patterns to arrest development in the pupal stage, which leaves larvae available as food for wildlife but prevents the emergence of adults.  Methoprene is an insect growth regulator supposedly of low toxicity to mammals that disrupts normal growth patterns to arrest development in the pupal stage, which leaves larvae available as food for wildlife but prevents the emergence of adults.  Other insect growth regulators, like dimilin, kill larvae when they molt by interfering with outer shell development.  Unfortunately, other insects and crustaceans can also be killed upon molting by disruption of the same processes.  Try an overall broadcast application of Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaner, but remember enzymes will also kill all insects even the beneficial ones.  Try applying dilutions of various essential oils to pulse points on your body every hour or so as described in the section Blood Feeders Overview.  If practical, wear two layers of tightly knit or woven (tucked in) clothing, avoid sandals, floral prints, loose clothing, the color blue (the preferred color of mosquitoes), hair spray, perfumes and other attractive fragrances.  Stay away from stagnant water.  If in a serious attack cover your skin with mud and/or seek immediate refuge in a building or a thicket or body of water.  Fog/mist the area with Kleen Kill® (Kleen'em Away Naturally™)  enzyme cleaners and/or Kleen Kill® (Kleen'em Away Naturally™)   peppermint soap or Not Nice to Bugs™ or Not Nice to Mosquitoes™ or garlic oil to down/destroy/repel mosquitoes.  You can also lightly dust the area with food grade diatomaceous earth.

Mosquitoes - Typical First Strikes by Housekeeping & Maintenance

  1. Remove all sources of stagnant or standing water if possible, e.g., old tires, bird baths, cans, trash barrels, wading pools, etc., or add Kleen Kill® (Kleen'em Away Naturally™)  Enzyme Cleaners, at a rate of a few drops per gallon of water.

  2. Spray the area and drains with Kleen Kill® (Kleen'em Away Naturally™)  Enzyme Cleaners or Not Nice to Bugs® (4 oz. per quart of  water). Remove or spray bushes and dense shrubbery and vines by doors and patios with hose end sprayers and enzymes (2 oz. per gallon).  Adding xanthan gum to water kills mosquito larvae.

  3. Turn on fans to “blow them away.”  Sit in the breeze (even if it is from a fan).  They will not bother you.

  4. Mosquito bite relief: Soak bites in Epsom salt water or apply a paste of salt or enzymes mixed into lard or cold cream.

  5. Spraying diluted Kleen Kill® (Kleen'em Away Naturally™)  Enzyme Cleaners (5 oz. per gallon) or garlic oil will control mosquitoes immediately.  Peppermint or lemon oils kill mosquitoes and other insects.

  6. Rub citronella oil or soybean oil or scented geraniums on clothing or exposed areas or burn citronella   candles.

  7. Pennyroyal, rubbed on the skin (if your are not sensitive), tansy or scented geraniums planted near a door, or basil plants will repel mosquitoes.  Wear protective clothing or put geraniol or geranium oil,   or Noxema, soybean oil or vinegar on the skin if you are not sensitive.

  8. Practice proper exclusion; repair 16 to 18 mesh screens; seal windows and doors and caulk. 

 9.  Lightly dust the surface of the water with Safe Solutions, Inc. food gradediatomaceous earth or powdered starch. 

10.  Caution - Test anything you want to put on your skin on a small area first.

11.  Some people are more attractive to mosquitoes than others.  Mosquitoes are attracted to dark clothing, carbon dioxide and sweat.  Prime feeding timesare late dusk and early evening.  Some people react more seriously to mosquito saliva, the chemical that causes the bites to swell and itch.  Carry a small “spritzer”  bottle filled with diluted Kleen Kill® (Kleen'em Away Naturally™)  enzymes, apply and rub into to bite area - this will reduce the swelling and itching.

12.  If you still are seeing mosquitoes, read the entire chapter.

Murphy’s Law of Pest Control:  To treat a malaria outbreak in Borneo in the 1950s, the World Health Organization (WHO) decided to spray DDT to kill mosquitoes.  The DDT also killed parasitic wasps which were controlling thatch-eating caterpillars.  As a result, the thatched roofs of many homes fell down, and the DDT-poisoned insects were eaten by geckoes, which were in turn eaten by cats.  The cats perished, which led to the multiplication of rats, and then outbreaks of sylvatic plague and typhus.  To put an end to this destructive chain of events, WHO had to parachute 145,000 live cats into the area to control the rats.

The following is from "The Coming Plague" by Laurie Garrett.  The book was copyrighted in 1994 and the situation has become worse since then: "It seems we have a much greater enemy in malaria now than we did just a few years ago," Dr. Wen Kilama said.  The director-general of Tanzania's National Institute for medical Research was frustrated and angry in 1986.  He, and his predecessors, had meticulously followed all the malaria control advice meted out by experts who lived in wealthy, cold countries.  But after decades of spending upward of 70 percent of its entire health budget annually on malaria control, Kilama had a worse problem on his hands in 1986 than his his predecessors in 1956...Since the days when optimists had set out to defeat malaria, hoping to drive the parasites off the face of the earth, the global situation had worsened significantly.  Indeed, far more people would die of malaria-associated ailments in 1990 than did in 1960...In 1990 more than 80 percent of the world's malaria cases were African; 95 percent of all malarial deaths occurred on the African continent.  Up to half a billion Africans suffered at least one serious malarial episode each year, and typically an individual received some 200-300 infective mosquito bites annually.  Up to one million African children died each year of the disease.  And all over the continent the key drugs were failing.

DEET warnings:  In April, 1998 EPA quietly announced products containing DEET can no longer be labeled as “child-safe” and must contain many new restrictions when using on children.  EPA has given the industry 26 months to apply the new restrictions and allowed the old labeled repellents to be sold for another 50 months — so you will not see the new restrictions for a long time.

DEET-free Products - Naturale Ltd. in Mineola, NY makes a timed vapor release glo-wristband using 30% geraniol that supposedly is reuseable for up to 60 hours.  It is advertised to repel mosquitoes, gnats and fleas in all outdoor activities including swimming.  Your body heat activates the volatile oil in about 10 - 15 minutes.  It may cause a skin reaction in rare cases.  Naturale makes several other DEET-free products and can be reached at 1-516-829-1540.  Bite Blocker is another insect repellant on the market that combines soybean oil, geranium oil and coconut oil; this product is said to be far superior to DEET and Skin-So-Soft.  Buy or make your own DEET-free repellants.

American Biophysics based in East Greenwich, RI is marketing the Mosquito Magnet, a device about the size of a gas barbecue that emits a plume of carbon dioxide that attracts mosquitoes.  The device then sucks them into a small vacuum where they dehydrate and die within a day.  Biosensory, Inc. of Willimantic, CT is expected to market the Dragonfly, a similar trap in the shape of an 18” bird.

Mosquito Attractant - The summer cypress, a/k/a the burning bush because it is so deep red in the autumn, contains an oil or fatty acid in its seeds that can be used or converted into a pheromone-like substance that attracts females of all Culex species to a water source where they can lay their eggs. Squeeze the oil from the seeds and place it directly near water diluted with 1 part Kleen Kill Enzyme Cleaner per 500 - 1000 parts of water.

The Asian tiger mosquito occurs throughout the Orient and earlier in the 1900s invaded Hawaii.  It invaded Texas in 1985 and had invaded most southern states east of the Mississippi and as far north as Ohio, Indiana, Delaware, Illinois and Maryland within 3 years.  How did we get this pest?  In 1983 - 1985 we paid for 4.5 million used truck tires to be sent from Asia to be retreaded and sold.  Asian tiger mosquitoes first arrived into our port cities in ship loads of these tires. Their eggs can survive for months out of the water waiting for some rain to cause them to hatch.  The female is an aggressive daytime feeder with a “racing stripe” and can lay 300 eggs per female.  Feeding occurs mainly in the early and/or late afternoon.  Walk in the shade and you will soon be surrounded by hungry females who will hit you low (ankles and knees).  You probably will not even hear them buzz!  You may have many bites and yet not have felt one bite!  The Asian tiger mosquito is considered to be a potential vector of encephalitis and other arboviruses!  Because it likes to breed in little pools of water, it could become a major back yard pest.  It can go from egg to biting adult in 2 weeks!  Treat tires with diluted Kleen Kill® (Kleen'em Away Naturally™)  Enzyme Cleaner, olive oil and/or lemon juice or citric acid.

Lime - It has been suggested by a field engineer that lime be added to stagnant water to control mosquitoes, but I have not yet field tested this control technique as to dosage or safety or efficacy.

Marigolds, Tagetes minuta (L.) - Whole plant extracts of this species of marigold are extremely toxic to adults and larvae of mosquitoes, e.g., Aedes aegypti (L.).  Caution: The extracts may also kill or negatively effect non-target aquatic insects and other organisms.  Add a little mineral or canola oil and dish soap to your mix and add to stagnant water.

Noxema - We have found that Noxema applied to the exposed skin repels mosquitoes.

Potential Bait - I was told to put a few drops of Lemon Joy dishwashing detergent on a white plate to attract and kill mosquitoes - I am looking forward to trying this on several species.

Isostearyl Alcohol Ethoxylate -  This non-irritating alcohol derived from plant oils has no odor and is used in the cosmetic industry.  When it is applied to standing water at about a quart per acre, it will quickly cover the entire surface and control mosquito larvae and pupae.  The film reduces the surface tension of the water so larvae and pupae can not attach easily and it also blocks their breathing tubes.  Done properly, the film is not visible, phytotoxic or toxic to most non-targeted species. 

Panic Caution:  In 1999 the City of New York found the vector of West Nile virus from birds to man to be the Northern House Mosquito, Culex pipens (Linnaeus).  The adults are brownish with white or gray markings with dark legs.  These particular mosquitoes are the only known vectors of West Nile virus and fly only 100 - 300 feet in their lifetime and are only minimally active at night.  They only breed in artificial containers, ditches, bird baths, sewers and polluted water.  New York City had isolated incidents of infestation, yet chose to give out Deet to “protect” all of the children and to bomb all five boroughs during the daytime with helicopters and trucks.  There were pictures in the newspapers of the spraying and of children putting Deet on during the day.  None of these daytime “controls” would work, but the frost did.  Then in 2000 the City decided to again “protect” the people.  Their plan does not mention the dangers of their “registered controls”.  Their “plan” does not mention “organophosphates” nor alert the populace of the health effects of their poison “controls”.  Their “plan” does not consider safer, simpler and far more effective alternatives that take into consideration the species of mosquito that they are “trying to control.”  At an NCAMP meeting I noted that if I had violated the pesticide labels and the federal law that states that it is illegal to say that even the labeled use of any pesticide is “safe” as much as the City of New York had done during the Fall of 1999, I would have been arrested.  Sit in the breeze of a fan, have the people drain or remove the breeding sources or add a little lime, soap, vegetable or diluted enzymes to the stagnant water.  These mosquitoes are not very active biters (even at night) so keep on moving. 

Newsday noted in August, 2000 that six mosquito species have been found to carry the West Nile virus (WNV) and each has different breeding and feeding habits.  The New York area is home to at least 75 different species or types of mosquitoes, most of which have not been tested for their ability to carry West Nile virus.  Scientists at the U. S. Army Medical Research Institute of Infectious Diseases at Ft. Detrick, MD have tested 18 species and found they all were capable of transmitting the disease to some degree in their laboratories.  Finally, a laboratory in Beloit, WI announced on 10/26/00 that birds in its laboratory became ill with WNV from other infected birds without any mosquito vectors.  I would like to point out that to try to “control” every mosquito using volatile pesticides simply will not work.

I do not believe in the thesis, “Let the buyer beware.”  I prefer one that states: “Let the seller/applicator be honest.”

 (6/18/2001:  Steve is currently working on a self-generating enzyme "brew" that can be produced on site for a few pennies a gallon. The material produced shows unbelievable potential. It is safe enough for people and animals to drink as a vitamin and mineral supplement. One gallon per 1000 square feet of soil improves water retention, removes toxins, increases crop production a minimum of 20%, and increases and/or re-establishes micro-organisms in the soil. When applied to water, it digests sewage and sludge and greatly improves the oxygen content of the water without aeration. Mosquitoes can not survive in the brew of algae and aerobic bacteria. Warts (97%) simply dissolve when washed with the material. Using one quart of brew per gallon of water with a cap of dish soap creates a wonderful cleaner for virtually everything. As time and research data progress, Steve will keep us informed on this very important research.  

6/25/2001:  The last week of June, I was in the Arizona desert watching this product being mixed into the irrigation ditches at a dilution rate of 1 part per million.  I found no mosquitoes in any drainage ditches but the tadpoles and other aquatic life were unaffected. - Steve)

I became a community activist in 1995.  Because of my success as an activist and uncovering corruption in the system, I gave up my successful corporate career of 30 years in the computer field in 1997 to concentrate on building a career as an advocate for all.

My word of honor!

It's unfortunate that money talks and everyone else walks in today's society.  Contribute what you can to help me get elected.
