Ground Treatment Maps

The maps below show the boundaries of areas where the District will conduct ground spraying to control adult mosquitoes due to either high adult mosquito abundance or West Nile virus activity. Spraying may involve the use of truck and ground foggers. When weather permits, spraying can occur between 7:00pm-12:00am, or 5:00am-8:00am. Check the Spraying Update page for details and the latest updates.
