Current Status of Aedes Mosquitoes

What are the Invasive Aedes Mosquitoes in Los Angeles County?

The three invasive species are the Asian tiger mosquito (Aedes albopictus), yellow fever mosquito (Aedes aegypti) and Australian backyard mosquito (Aedes notoscriptus) do not belong in our natural Southern California environment.

These species are a public health concern throughout the US, including California since they can transmit Zika virus, dengue fever, yellow fever and chikungunya. See where else they are in the state (PDF).

These mosquitoes adapt very well to urban environments (cities). Once introduced, they can thrive in our neighborhoods. While the Greater Los Angeles County Vector Control District is working hard to fight these invasive insects, we can’t do it alone. We need your help.

How Are They Threats to Our Life in the Cities?

The Asian tiger mosquito and yellow fever mosquito (both popularly known as “invasive Aedes mosquitoes”) have the potential to transmit debilitating viruses. These diseases have not been transmitted locally (no local outbreak).

However, if a person with the virus spends time in an area where these mosquitoes are found, there is an increased chance of an outbreak occurring in Los Angeles County. Currently, many people visiting known Zika outbreak locations in the U.S. are capable of returning to L.A. County infected — and may not even know it. The

Australian backyard mosquito is a concern for the veterinary community since it can transmit canine heartworm.

These daytime biters can ruin a family get-together or a warm day at a park. Normally, we expect mosquitoes to bite from dusk to dawn – not so with these invasive mosquitoes.
Do you have an old tire in your yard? Or maybe some plant cuttings in a bucket of water in your kitchen?

These mosquitoes can lay their eggs in stagnant water sources as small as a bottle cap! There have been reports in Los Angeles County of these mosquitoes biting people inside offices and homes.
