West Nile Virus

Vector Update

West Nile virus is endemic to Los Angeles County, and wet weather can increase virus activity and mosquito populations. Visit VectorSurv Maps or for a comprehensive look at this year’s West Nile virus activity throughout Los Angeles County and Southern California.

Mosquito control is a shared responsibility and residents must take an active role in reducing the threat of mosquitoes and mosquito-transmitted diseases in their neighborhoods by taking the following steps: 

  • Eliminate standing water in clogged rain gutters, rain barrels, discarded tires, buckets, watering troughs or anything that holds water for more than a week.
  • Ensure that swimming pools, spas, and ponds are properly maintained. 
  • Change the water in pet dishes, birdbaths, and other small containers weekly. 
  • Request mosquitofish from your local vector control district for placement in ornamental ponds. 
  • Wear EPA-recommended insect repellent when outdoors where mosquitoes may be present. 
  • Report neglected (green) swimming pools in your neighborhood to your vector control district.
