Aerial adult mosquito treatment in Lincoln and agricultural areas of west Placer Sept. 21, 2017 8:00 – 11:00 PM

Areas of Lincoln and western Placer County 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 elevated West Nile virus activity.

Treatment areas (Click on map for larger image):


  • Residential areas east of Aviation Blvd/Nelson Lane to Lincoln Blvd/Old Hwy 65, bordered by 5th Street on the south.


  • Agricultural and rural areas north of Baseline Road to Jackson Road between Country Acres Lane and Locust 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.
