Mosquito Control sprays insecticide with low-flying aircraft over rural and residential areas of Duval County. Missions are typically flown during dusk or dawn. Spraying is necessary to control biting adult mosquitoes, which pose a potential public health threat by spreading West Nile virus.

Planned Neighborhood Spraying

Mosquito Control typically sprays areas in Jacksonville between 7 p.m. and 11 p.m., Monday through Thursday. Starting mid-April, crews will be dispatched around Jacksonville to fog for adult-biting mosquitoes. We typically do not list the areas we are planning to fog by truck, but check out our Ground Fogging page to see if we have sprayed your neighborhood recently.
