ROSEVILLE, Calif.  – Ongoing West Nile virus activity in Lincoln prompts the PlacerMosquito and Vector Control District to respond with ground-based mosquito treatments.

Even though residents may perceive that mosquito season is over and the threat of West Nile virus has subsided, the District is still seeing significant West Nile virus and mosquito activity in Lincoln and is taking advantage of a break in the cool weather to conduct treatment for adult mosquitoes.

The District has scheduled ground-based adult mosquito treatments for the early morning of September 24 in the following areas of Lincoln:

  • Most residential areas west of Highway 65, including some green open space areas along Auburn Ravine by Moore Road.

Since several factors affect spraying activities, such as weather and wind conditions, the District encourages Placer residents to check the District website at for any changes to the spraying schedule.

With West Nile virus spreading to more populated areas of the county, the Placer Mosquito and Vector Control District advises the public to implement the 3 Ds of protection:

  • Drain any standing water that may produce mosquitoes.
  • Defend yourself and your home by using an effective insect repellent, dressing protectively when outside, and making sure screens on doors and windows are in good condition.
  • Contact the District for any additional help controlling mosquitoes around your home, or to report potential mosquito breeding sources, such as neglected swimming pools.
