West Nile virus is endemic to Los Angeles County, and wet weather can increase virus activity and mosquito populations. Visit VectorSurv Maps or WestNile.ca.gov 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.
