Press Release

(Woodland, CA) - The Yolo County Health & Human Services Agency received notification confirming the first two mosquito samples of the season have tested positive for West Nile virus (WNV) near Zamora, CA.

“This finding serves as a reminder that mosquitoes carry disease that can harm humans and that mosquito control is everyone’s responsibility,” said Dr. Ron Chapman, Yolo County Health Officer.

With the past winter flooding followed by intermittent warm weather and sporadic rains, it is important that people protect themselves from mosquito bites. Residents and visitors of Yolo County can reduce their risk of WNV infection and other mosquito-transmitted diseases by taking these precautions:

  • Eliminate all sources of standing water on your property that can support mosquito breeding.
  • Apply insect repellent containing the active ingredient DEET or Picaridin when outdoors, according to label instructions.
  • Avoid spending time outside when mosquitoes are most active, at dawn and dusk, and especially for the first two hours after sunset.
  • When outdoors, wear long pants, long-sleeved shirts and other protective clothing.
  • Keep mosquitoes out of your home with tight-fitting screens on doors and windows.
  • Contact your veterinarian for information on vaccinating equine against WNV.
  • Report significant mosquito infestations to the Sacramento-Yolo Mosquito & Vector Control District at or (800) 429-1022.
  • Report dead birds and tree squirrels to 1-877-WNV-BIRD (1-877-968-2473) or
