Non-native aedes aegypti mosquitoes detected in the County of Santa Clara

The County of Santa Clara Vector Control District has confirmed the presence of the invasive Aedes aegypti mosquitoes in the county. Two adult Aedes were detected near the intersection of Dixon Landing Road and McCarthy Boulevard in San Jose.

This mosquito is of special concern because it has the potential to transmit a variety of diseases, including Zika, dengue, chikungunya, and yellow fever. Unlike some of our native mosquitoes that breed in marshes and swamps, Aedes aegypti prefer containers and live in close proximity to humans and thrive in areas like our backyards. The invasive species is about a quarter inch in size with black and white stripes on its back and legs. It is an aggressive mosquito that will bite at any time of day, even indoors.

The District is carrying out an eradication plan to combat the aggressive mosquito species and urges residents to help protect the community by removing sources of standing water on their properties. It's important for residents to look around their yard and outside their home and dump out even the smallest amount of standing water. Cleaning and scrubbing bird baths, pet dishes and other containers is a good way to remove any lingering Aedes aegypti eggs, which look like tiny black seeds.

Residents experiencing mosquito bites during the day should report them immediately to the Vector Control District at (408) 918-4770 or [email protected]. For more information, a list of prevention tips, and safety recommendations, please read our press release.
