Question

Answer

Why do you continue to spray
even thought it is dry?
When it is dry out the normal aides vexin mosquitoes population are lower but the culex pipiens (disease carries) are allot higher % then when it wetter out so we continue spray to keep the culex pipiens down and try to avoid problems.
What action is takeing when
spraying around large groups?

We try to eliminate the spray plum from encompassing the area.
(Although we did have a mayor called one morning after we sprayed past his party saying he was slightly put out as we sprayed past but as the attendees came up praised the small town attitude of taking care of his constituents to which he replayed in a small town we don't have constituents we look after our friends.)

How far can mosquitoes fly?
Mosquito species preferring to breed around the house, like the Asian Tiger Mosquito, have limited flight ranges of about 300 feet. Most species have flight ranges of 1-3 miles. Certain large pool breeders in the Midwest are often found up to 7 miles from known breeding spots. The undisputed champions, though, are the salt marsh breeders - having been known to migrate up to 100 miles in exceptional circumstances, although 20 to 40 miles are much more common when hosts are scarce. When caught up in updrafts that direct them into winds high above the ground, mosquitoes can be carried great distances.
Is the spraying dangerous to me and my family?
Another common question…the product used for mosquito spraying has a very low toxicity to mammals, as well as dogs, cats, birds and other organisms. The acute toxicity is very low compared to common substances that people are routinely exposed to, such as caffeine and nicotine, and even over-the-counter medications.

How do mosquitoes grow?

Mosquitoes have a very interesting and unique biology. They go through 3 stages before maturity - egg, larvae and pupae. Each species has a different set of conditions required to complete this process. Some species lay eggs on damp soil, where they can remain for years before hatching. Another species needs emergent vegetation (such as the common cattail) to complete this process. One basic fact that is constant for all species - stagnant water is required for the maturation cycle.

How long do mosquitoes live?
Life span vary by species. Most adult female mosquitoes live 2-3 weeks. Some species that over-winter in garages, culverts and attics can live as long as 6 months.
Why do mosquitoes feed on blood?
Female mosquitoes imbibe blood so that their eggs can mature prior to laying. It serves no nourishment function. Males do not take blood meals at all. In order to obtain energy, both male and female mosquitoes feed upon plant nectars
Do those new propane mosquito traps I see in the stores work?
These devices will, indeed, trap and kill measurable numbers of mosquitoes. Whether this will produce a noticeable reduction in the mosquito population in your case will depend upon a number of factors, e.g. your tolerance level, absolute mosquito population size, proximity, size and type of breeding habitat producing re-infestation, wind velocity and direction, and species of mosquito present, among many other things. Depending upon their placement, wind direction, and trapping efficiency, traps may actually draw more mosquitoes into your area than they can possibly catch. Thus, the homeowner must still use repellents and practice source reduction methods as adjuncts to realize any measure of relief.
Which mosquitoes transmit WNV?
At least 43 species of mosquitoes have been found infected with the West Nile virus in the United States. Not all of these, however, are capable of maintaining the virus in such a manner as to permit them to transmit it among organisms. Many of these infected mosquitoes feed only upon birds, thus contributing to a cycling of the virus among avian populations. Other species feed upon these infective birds and then will feed upon mammals, including humans. These are called "bridge vectors" because they serve as a conduit for the virus to travel from its reservoir in birds to its final host in humans or other mammals. In urban settings, Culex pipiens is usually the primary vector. In rural areas, particularly in the western part of the United States, Culex tarsalis is the primary transmitter.
What are "larvicides" and "adulticides"? Larvicides are products used to kill immature mosquitoes. They can be either biological (such as toxin from specific bacteria that is lethal to mosquito larvae but not to other organisms) or chemical products, such as insect growth regulators, surface films, or organophosphates. Larvicides are applied directly to water sources that hold mosquito eggs or larvae. When used well, larvicides can help to reduce the overall mosquito by limiting the number of new mosquitoes that are produced.
What are Synthetic Pyrethroids?

Pyrethroids are synthetic chemical insecticides that act in a similar manner to pyrethrins, which are derived from chrysanthemum flowers. Pyrethroids are widely used for controlling various insects. Permethrin, resmethrin, and sumithrin are synthetic pyrethroids commonly used in mosquito control programs to kill adult mosquitoes.

Do Pyrethroids Pose Risks to Human Health? Pyrethroids can be used for public health mosquito control programs without posing unreasonable risks to human health when applied according to the label. Pyrethroids are considered to pose slight risks of acute toxicity to humans, but at high doses, pyrethroids can affect the nervous system.

How are Larvicides Used in Mosquito Control?

 

State and local agencies in charge of mosquito control typically employ a variety of techniques in an Integrated Pest Management (IPM) program. An IPM approach includes surveillance, source reduction, larviciding and adulticiding to control mosquito populations. Since mosquitoes must have water to breed, source reduction can be as simple as turning over trapped water in a container to undertaking large-scale engineering and management of marsh water levels. Larviciding involves applying pesticides to breeding habitats to kill mosquito larvae. Larviciding can reduce overall pesticide usage in a control program. Killing mosquito larvae before they emerge as adults can reduce or eliminate the need for ground or aerial application of pesticides to kill adult mosquitoes.
