Aerial adult mosquito treatment in Roseville Sept. 29, 2017 7:00 – 11:00 PM

A small area of Roseville is 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 elevated West Nile virus activity.

Treatment areas (Click on map for larger image):

  • Residential areas of western Roseville, west of Fiddyment Road

Note: 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.
