Mosquito Control Pesticides

How to Opt Out from Mosquito Control Spraying

Adulticiding is a chemical control method used to control mosquitoes at high mosquito densities or to suppress mosquito-borne disease (arbovirus) threats. This approach may involve the use of highly specialized truck-mounted equipment to target treatments to selected areas.

The boundary of the excluded property must be marked with white plastic or aluminum pie plates, a minimum of 9 inches in diameter, with the words “No Spray” clearly written in permanent marker. Plates must be placed on trees, stakes, or poles that are easily visible from the street, at least every 50 feet along the property boundary adjacent to the road, and no more than 5 feet from the road.
