Permethrin is a pyrethroid-based pesticide registered for use in mosquito control by the Environmental Protection Agency and New York State Department of Environmental Conservation. It is effective against adult mosquitoes, including the Culex species, which transmitted West Nile virus last year. Permethrin has a long history of being applied agriculturally to control against pests in the production of fruits, vegetables, and other crops. It has not been known to cause any chronic toxic effects to humans. Mild eye and skin irritation may occur with exposure to permethrin which can be treated by washing the eyes and skin thoroughly with water after contact.

It is not toxic for household pets and is virtually non-toxic to birds. It can be toxic to fish and caution would be used before applying it in areas which would result in aquatic exposure. It breaks down readily in soil and water, making it unlikely to leach or contaminate groundwater.

Children or adults who have asthma or a respiratory condition should stay inside if spraying occurs. In addition, windows and doors should be closed and air conditioners should be shut off.
