Due to suboptimal weather conditions on Thursday night, residential areas of western Roseville are again scheduled for treatment on Sunday. 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.
- Residential areas of Roseville, 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 spraying schedule. For an overview of our mosquito control programs, you may view the District video.
Depending on weather conditions, the pilot may have to perform an “offset treatment”. This means that residents may see the plane flying outside of the designated treatment area in order to compensate for wind speed and direction and to ensure that our public health materials are reaching the intended area scheduled for the treatment.
