This form is ONLY for notification of when insecticide applications for adult mosquitoes are made. It is NOT A REQUEST FOR SPRAYING.

Weather permitting, the District will make insecticide applications to reduce the number of adult mosquitoes in response to disease risk or in response to extremely high numbers of adult mosquitoes. The decision to make an adulticide application is based on surveillance data. Surveillance data includes mosquitoes collected by various trapping methods, mosquito test results and reports from the Fresno County Department of Public Health on suspected mosquito-borne disease cases.

The decision to make an application is made when updated surveillance data becomes available. In many cases we cannot provide more than a few hours of notification, but the District will work to provide the earliest notification possible.
