Mosquito Spraying

Mosquito spraying is one of the most commonly employed ways to discourage certain harmful mosquitoes from breeding. Because there are chemicals spread over areas where people live, the spraying of mosquitoes raises a lot of questions like: are those pesticides safe for my health? Will this impact my animals? What about the items left outdoors, which are influenced by spraying the mosquito? And so forth. We will try to answer some of those questions in this article.

Mosquito spraying is done with mounted fogging units as an ultra-low-volume (ULV) spray to apply insecticides. Such spray systems dispense very small droplets of aerosol (fog), which stay aloft and destroy mosquitoes on contact. Compared to the area treated, the amount of insecticide used in mosquito spraying is small , usually around 3 to 5 ounces per acre, which minimizes exposure and risks to people and the environment. Mosquito spraying is often performed by thermal foggers use an oil carrier that is covered in a thick smoke-like fog to spread the pesticide.Interested readers can find more information about them at

Moving mosquitoes within the treated region are destroyed during mosquito spraying. Despite decreasing the local mosquito population for a few days, fogging does not deter mosquitoes from re-entering the area.

Pyrethrins, organic pyrethroid insecticides (such as Scourge ® and Anvil ®), and malathion are the most widely used materials of mosquito spraying. Pyrethrins are insecticides that come from the chrysanthemum flowers collection. Pyrethroids are forms of pyrethrins made by humans. Both function as touch poisons which affect the nervous system of the insect. They are combined with a synergist (such as piperonyl butoxide) for mosquito spraying which enables the insecticide to be more efficient by limiting the enzyme used by insects to detoxify the pyrethrins.

Pyrethrins and pyrethroids are used to spray mosquitoes without posing unreasonable risks to human health when applied according to the label although pyrethroids can affect the nervous system, coughing, wheezing, shortness of breath , chest pain, runny or stuffy nose in high dosage. These two insecticides do not face unnecessary threats to wildlife and the climate, too. These are poor in risk to humans as used in mosquito control, and are practically non-toxic to animals. They are nevertheless poisonous to fish and bees. Thus E.P.A (Environmental Protection Agency) prohibits the spraying of mosquitoes in open water or within 100 feet of lakes , streams , rivers or bays.

Malathion is an insecticide with organophosphate that was first registered in the United States in1956. It is used to destroy insects on farm crops, on storage goods, on golf courses, in home gardens and in outdoor sites where trees and shrubs are cultivated at home and often used for spraying mosquitoes. Malathion comes in two forms: a pure form of a colorless liquid and a solution of technical grade (brownish-yellow liquid), containing malathion (greater than 90%) and impurities in a solvent. The malathion, practically, tastes like garlic.
