Invasive Asian Tiger Mosquitos Found in L.A. County

The Greater Los Angeles County Vector Control District is warning residents that an infestation of Asian tiger mosquitos has been found in South El Monte.

This aggressive, day-biting mosquito has not been seen in Los Angeles County since 2001, when it was brought to this country accidentally in a shipment of plants from southeast Asia.

"This day-biting and disease-spreading mosquito would significantly impact everyone's way of life if it were to establish itself here in Los Angeles," said Mark Daniel, director of operations, in a statement. "We are urging residents to help us stop the spread of the species by immediately eliminating any potential breeding sources around their homes and to alert the District if they find possible Asian tiger mosquitoes in their neighborhoods." 

Asian tiger mosquitos are known for having a unique size - 1/4 inch long - and black and white bands across the body and legs. The species lays individual eggs next to the surface of standing water, as well as in old tires, flower pots, buckets, and other containers. Eggs hatch in warm temperatures once they are fully covered by water, and deposited eggs have the ability to hatch after several years under the right circumstances.

The mosquito is a vector of numerous debilitating diseases, including yellow fever and encephalitis, and is resonsible for the recent outbreak of dengue virus in Texas, Hawaii, and south Florida. Residents are urged to ensure that there is no standing water in their yards, and encouraged to clean outdoor containers.
