Public Health Advisory: Mosquitoes & Other Insects and Vectors in LA County

Post Date:06/30/2017 9:59 AM

With the weather warming up and more of the public spending time outdoors, it is helpful for the public to understand the vectors and vector-borne diseases encountered in Los Angeles County. The Los Angeles County West Vector Control District serves the City of Palos Verdes Estates by providing public information, assisting with vector-related injuries, and vector control services.

Below is a list of common vectors and vector-borne diseases in Los Angeles County:

Mosquitoes and West Nile Virus

West Nile virus (WNV) is primarily transmitted by infected mosquitoes. Since 2004, WNV activity has been detected in all 58 counties in California and surveillance efforts have shown that the virus remains active throughout Los Angeles County. In 2016, 442 human infections and 19 deaths were recorded throughout the state.

We recommend that residents and visitors be advised of West Nile virus risks in open and recreational areas with the posting of the attached West Nile virus warning signs. A master copy for duplication has been included with an area to add your contact information if desired. These signs should be prominently posted by your staff in all areas within your jurisdiction that are accessible to the public during evening hours, especially dawn and dusk.

Invasive Aedes Mosquitoes and Zika Virus

Zika virus is primarily transmitted by Aedes aegypti (yellow fever mosquitoes) and possibly Aedes albopictus (Asian tiger mosquitoes). These are non-native, invasive species which are now found throughout much of California, including Los Angeles County. Local transmission by these mosquitoes has not occurred thus far in California. All California cases have been in people who were infected while traveling outside the U.S. Visit and for the latest information on Zika virus.

Africanized Honey Bees

Los Angeles County has been completely colonized by the Africanized honey bee since April 1999. The Los Angeles County West Vector Control District will remove non-structural beehives and swarms in our jurisdiction Monday through Friday from 8:00 a.m. to 4:00 p.m. with the exception of some height and safety limitations. If you wish to request removal of a bee swarm or colony outside a home or business in your area, please call (800) 825-3400.

Ticks & Lyme Disease

Lyme disease is a bacterial infection transmitted by the bite of the western black-legged tick, Ixodes pacificus. Studies have shown that approximately 1%-2% of western black-legged ticks found in the Santa Monica Mountains, Palos Verdes Peninsula, and other rural areas of Los Angeles County carry the Lyme disease bacteria. The adult western black-legged tick is most active from late November through May.

Red Imported Fire Ants

The red imported fire ant (RIFA) is a species of ant known for its aggressive behavior and painful sting. Red imported fire ant colonies have now been found in five Southern California counties, including Los Angeles. RIFA may infest lawns, gardens, golf courses and parks, where they pose a health threat to people, pets and wildlife. If a RIFA infestation is suspected in your area, please call (310) 915-7370 for a free inspection of the property.
