Following recent wildfires in areas like Eaton Canyon and Pacific Palisades, vector control officials are warning that untouched swimming pools—especially at vacant or damaged properties—are becoming mosquito breeding zones.

Just one neglected pool can produce up to 3 million mosquitoes per month, potentially spreading West Nile virus and other mosquito-borne diseases.

Aerial surveillance in the Eaton Fire zone identified over 1,300 unmaintained pools and thousands more are suspected throughout the region. Officials are now conducting free mosquito control treatments, including larvicides and mosquitofish, to reduce the public health risk.

What Residents Should Know:

✔️ Mosquitoes can appear as early as April
✔️ Pools near populated areas are being prioritized
✔️ Property owners are normally responsible, but treatment is currently free
✔️ Standing water is a public health concern under California law

If you have a pool affected by the fires, don’t wait — contact your local vector control agency. CCMAD encourages residents to report unmaintained pools or stagnant water at comptoncreekmad.org or by calling your district office.
