The residential areas in Sheridan, Lincoln, and Roseville are scheduled for treatment. 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 very high West Nile virus activity.
Treatment areas are below. Click on the maps for a larger picture:
- The community of Sheridan and surrounding areas
- Lincoln – residential areas west of Lincoln Blvd. and south of the Auburn Ravine
- Roseville – residential areas west of Fiddyment Road between Blue Oaks Blvd and Baseline Blvd.
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.
