Aerial Adult Mosquito Treatment in western Placer 7-10-14 and 7-11-14 from 8:30-10:30 PM – RESCHEDULED

Treatment has been rescheduled to 7/11/2014 AND 7/12/2014, same time and areas. Treatment for 7/10/2014 was cancelled due to weather conditions.

The agricultural areas of western Placer County are scheduled for treatment.  An EPA-approved 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:

  • Western Placer County agricultural areas. North block, west of Sheridan and South block, west of Roseville. Please refer to the map here.

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.
