There’s a helicopter spraying pesticides in Manatee County for mosquito control. Is it safe?

Spraying pesticides over largely-populated areas is safe, according to Environmental Protection Agency guidelines.

Christopher Lesser, director of the Manatee County Mosquito Control District, said the county uses EPA-registered pesticides for aerial mosquito control such as malathion, which is safe to apply 1 to 3 fluid ounces per acre. Being EPA-registered means the sprays pose “no real risk” to humans, nature or wildlife when guidelines are followed. The spray releases from the aircraft as extremely small droplets and is designed to stay airborne as long as possible to kill mosquitoes on contact, according to the EPA. 

The most recent spray in Manatee County occurred on June 10, following an outbreak of mosquitoes after heavy local rains.

Mosquito control is mandated by law since the insect is considered a threat to public health and quality of life. Other methods for control include removing mosquito habitats or targeting them before they become adults.
