Areas in Roseville are scheduled for treatment for West Nile virus and mosquito activity. An EPA-approved mosquito adulticide will be applied in an Ultra Low Volume (ULV) fog by truck to target adult mosquitoes.
Treatment areas (Click maps to enlarge):
- From Fiddyment Road to the east to the Westpark neighborhoods on the west, Hayden Parkway to Blue Oaks Blvd to the north, to the neighborhoods south of Pleasant Grove Blvd on the south
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.
