Residents are being urged to continue to report dead birds and to reduce mosquito production sites on their properties. Here are a few simple ways to help reduce exposure to mosquitoes and lessen the risk of West Nile virus:

  • Check septic tank lids to ensure a tight seal, repair cracks and screen vent pipes using a fine mesh screen (1/16 of an inch).
  • Contact the Marin/Sonoma Mosquito & Vector Control District (707-285-2200) if you have a mosquito-related problem that you cannot resolve on your own. 
  • Check and maintain all window and door screens.
  • Continue to report dead birds to the West Nile Virus hotline at 1-877-WNV-BIRD or online.
  • Wear mosquito repellent when outdoors at dusk and dawn. Use a repellent containing one of the following active ingredients: DEET, Picaridin, oil of lemon eucalyptus, or IR3535. 
  • Avoid being outdoors during peak mosquito activity (dawn and dusk).
