Pyrethroids are chemicals that kill insects, including mosquitoes. They can be an important tool in helping to prevent the spread of West Nile virus. Mosquito control professionals mix pyrethroids with water or oil and apply it as an ultra low-volume spray that kills flying adult mosquitoes. Pyrethroids are also using in commerical and residential insect sprays, such as our PEST-O-MINT product.
When used properly, pyrethroids have been found to pose very little risk to human health and the environment. If you want to reduce your exposure to pyrethroid spray, stay indoors during spraying and for about 30 minutes afterwards.
