West Nile virus is endemic to Los Angeles County, and warm temperatures 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 WNV in their neighborhoods by taking these additional 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.
  • Change the water in pet dishes, bird baths, and other small containers weekly.
  • Wear EPA-registered and CDC-recommended insect repellent when outdoors where mosquitoes may be present.
  • Report neglected (green) swimming pools in your neighborhood to your vector control district.
  • Share this information with your community to decrease mosquito populations.
