Elevated West Nile Virus Risk in Lincoln and Nearby Rural Areas

Several West Nile virus indicators (dead birds and mosquito samples) have been detected in Lincoln and the surrounding area. This level of virus activity in this area is the highest so far for the season. The Placer Mosquito and Vector Control District has identified new areas of increased risk indicated by the red border and shaded in pink.

While we continue to work within this area to conduct localized mosquito prevention and control applications, and collect more data to determine the best response to this increase in West Nile virus activity, we are urging everyone who lives, works, or recreates in the risk area to implement ALL prevention measures, including:

  • staying indoors during peak mosquito activity times (approximately 5 – 8 AM and 5 – 10 PM)
  • using an effective insect repellent (containing DEET, picaridin, IR3535 or oil of lemon eucalyptus) if you have to be outside for ANY length of time. Now is not the time to experiment with scientifically-unproven materials and strategies.
  • making sure mosquitoes cannot gain access into your home by shutting doors and windows and keeping screens in good working order
  • eliminating standing water around your home and reporting any standing water areas in your neighborhood

We also encourage residents to visit this website regularly during this time of year for tips and updates.

Residents in previously identified elevated risk areas or areas that have received adult mosquito control applications in the past two weeks (West Roseville, Elverta area of South Placer, and Sheridan) are still encouraged to implement preventive measures to protect themselves from mosquitoes.
