Reports of dead birds are an early indication of that the virus is circulating in the environment. Residents are encouraged to help by reporting fresh carcasses of birds or tree squirrels to the West Nile Virus hotline, online at or by phone at 877-WNV-BIRD (877-968-2473).

To prevent mosquito breeding on your property and to prevent mosquito bites, follow the "Three D's":

  •  DRAIN - Mosquitos lay their eggs on standing water. Eliminate all sources of standing water on your property, including flower pots, old car tires, rain gutters and pet bowls.
  • DAWN and DUSK - Mosquitos bit in the early morning and evening so it is important to wear proper clothing and repellent if outside during these times. Make sure that your doors and windows have tight-fitting screens to keep mosquitos out.
  • DEET - Apply insect repellent containing DEET, picaradin, oil of lemon eucalyptus or IR3535 according to label instructions. Repellents keep the mosquitos from biting you.

For assistance with a mosquito problem in San Mateo County, contact the District at (650) 344-8592.
