Mosquito Fogger is one of the most commonly used methods to stop the breeding of these nasty insects. Due to the fact that there are chemicals that are spread over areas where people live, mosquito spraying raises a lot of question like : are those pesticides safe for my health? Does it affects my pets ? What about the objects left outside are they affected by mosquito spraying? And so on. In this article we will try to answer to some of these questions.
Mosquito spraying is done using mounted fogging units to apply insecticides as an ultra-low-volume (ULV) spray. These units spray units dispense very fine aerosol droplets (fog) that stay aloft and kill mosquitoes on contact. The amount of insecticide used in mosquito spraying is small compared to the area treated, usually about 3 to 5 ounces per acre, which minimizes exposure and risks to people and the environment. Mosquito spraying is also done by thermal foggers that use an oil carrier that is heated to disperse the pesticide in a dense smoke-like fog.
During mosquito spraying , flying mosquitoes within the treated area are killed. Although the local mosquito population is reduced for a few days, fogging does not prevent mosquitoes from re-entering the area.
The most commonly used products in mosquito fogger are pyrethrins, synthetic pyrethroid insecticides (such as Scourge ® and Anvil ®)and malathion. Pyrethrins are insecticides derived from the extract of chrysanthemum flowers. Pyrethroids are human made forms of pyrethrins. Both of them act as contact poisons, affecting the insect's nervous system. For mosquito fogger they are combined with a synergist (such as piperonyl butoxide) that allows the insecticide to be more effective by restricting the enzyme that insects use to detoxify the pyrethrins.
Pyrethrins and pyrethroids are use in mosquito spraying without posing unreasonable risks to human health when applied according to the label although, in high dosage, pyrethroids can affect the nervous system, coughing, wheezing, shortness of breath, chest pain, runny or stuffy nose. Regarding the wild life and the environment these two insecticides do not pose unreasonable risks, also. When used in mosquito fogger they are low in toxicity to mammals, and are practically nontoxic to birds. However they are toxic to fish and to bees. Therefore E.P.A (Environmental Protection Agency) prohibits the backpack mosquito fogger to open water or within 100 feet of lakes, streams, rivers or bays.
