Parts of western Placer are scheduled for treatment for high mosquito numbers and increased West Nile virus activity.  An EPA-registered mosquito adulticide will be applied in an Ultra-low Volume (ULV) fog by aircraft in an effort to address increased mosquito populations and West Nile virus activity.

Treatment areas (Click on map for larger image):

• Moore Ranch – south of Moore Road to Catlett Road, and from Brewer Road west to Canal St.

• Sheridan

Since several factors affect treatment activities, such as weather and wind conditions, the District encourages Placer residents to check this website regularly for any changes to the treatment schedule.  For an overview of our mosquito control programs, you may view the District video.
