Mosquito & Vector Control


Mosquito The Mosquito and Vector Control Program protects public health by controlling mosquitoes and other vectors that spread disease.

Mosquitoes, ticks, and rodents are not only a nuisance, but are a major threat to public health. This Program control vectors and nuisance pests using effective and environmentally sensitive methods to control disease vectors and nuisance pests, and reduce the risk of vector-borne diseases such as West Nile virus and plague.

What is a Vector?


A vector is any insect or arthropod, rodent or other animal of public health significance capable of harboring or transmitting the causative agents of human disease (such as West Nile virus and malaria). Under certain circumstance insects, arthropods and other animals capable of causing direct human injury or discomfort, but not disease, are sometimes referred to as vectors.

Yellow Fever Mosquito (Aedes aegypti) and Asian Tiger Mosquito (Aedes albopictus)


Two invasive (non-native) mosquito species have recently been found in several California cities and there is a potential for them to spread into other areas of California. They are named Aedes aegypti (the yellow fever mosquito) and Aedes albopictus (the Asian tiger mosquito). Unlike most native mosquito species, Aedes aegypti and Aedes albopictus bite during the day. Both species are small black mosquitoes with white stripes on their back and on their legs. They can lay eggs in any small artificial or natural container that holds water.

Zika


Zika virus is transmitted by Aedes aegypti mosquitoes (yellow fever mosquitoes) and Aedes albopictus mosquitoes (Asian tiger mosquitoes). These mosquitoes are not native to California. However, since 2011 they have been detected in several California counties. An Aedes mosquito can only transmit Zika virus after it bites a person who has this virus in their blood. Thus far in California, Zika virus infections have been documented only in people who were infected while traveling outside the United States or through sexual contact with an infected traveler. To date there has been no local mosquito-borne transmission of Zika virus in California.

Zika virus is not spread through casual contact, but can be spread by infected persons to their sexual partners. Zika virus infection in pregnant women can cause birth defects and other poor pregnancy outcomes. Additionally, there is an association between Zika and Guillain-Barré Syndrome (GBS), a disease affecting the nervous system.

Report a Dead Bird


Certain species of birds are very susceptible to West Nile virus and often die from it. Reporting dead birds and squirrels is a very helpful tool to our disease surveillance and monitoring efforts. The Mosquito and Vector Control Program and the California Department of Public Health use dead bird reports to help identify increased West Nile virus activity in an area.

If you see a bird that has been dead for less than 24 hours, please call 1-877-WNV-BIRD
(1-877-968-2473) or report it online here.
