Aggressive Non-Native Mosquito Found In Pleasanton

Authorities found a larva in a trap for Aedes aegypti, which can carry dengue, Zika, and yellow fever.

PLEASANTON, CA — The Alameda County Mosquito Abatement said that it discovered an Aedes aegypti mosquito larva in a trap placed in the Alameda County Fairgrounds.

The mosquito is not native to California, and can spread diseases such as dengue, Zika, and yellow fever. It is an aggressive mosquito that bites throughout the day, often near the ankles. They lay their eggs just above the waterline in small, artificial water sources like buckets, pet dishes, fountains, bird baths, plant saucers, and old tires.

The larvae was collected from a trap on July 30, and the district responded by inspecting and treating all known mosquito breeding sites in the area, and conducting intensive followup trapping, the district said in a news release.
