BUTTE COUNTY, CA (MPG) - The Butte County Mosquito and Vector Control District (District) detected an invasive (non-native) species of mosquito on Wednesday, October 28th, 2020. The Aedes aegypti, commonly known as the yellow fever mosquito, was found in west Oroville, in the area of Oroville Dam Boulevard and Feather River Boulevard. The California Department of Public Health confirmed the invasive species detection.

“The District is working to evaluate the extent of the infestation and we plan to do everything we can to eradicate this mosquito and to protect our residents from the potential disease risk of these invasive mosquitoes,” said Matt Ball, District Manager. “Our goal is to control and eliminate this species of mosquito so that it does not become established in our community.”

The District utilizes a science-based, data-driven approach to mosquito control. This Integrated Vector Management approach will include immature surveillance and control that includes door to door inspections, as well as adult surveillance and control, which will include ultra-low volume spraying, barrier treatments and a variety of live mosquito trapping.

The Aedes aegypti mosquito has been detected previously in Chico (Butte County) and other areas of California, but never in Oroville. Aedes aegypti have the potential to transmit viruses such as chikungunya, dengue, yellow fever, and Zika, that are not known to be transmitted by Butte County’s native mosquitoes.

The public plays a critical role in helping to control the spread of this mosquito population. “Aedes aegypti love to breed in small water-holding containers and prefer being in and around our homes.  A breeding ground for this mosquito can be as small as a water bottle cap. Eliminating all standing water regardless of size is essential to effective control,” says Matt Ball.

Prevent Aedes aegypti development in your yard:

Inspect your yard for standing water sources and drain water that may have collected under potted plants, in bird baths, discarded tires, and any other items that could collect water; Check your rain gutters and lawn drains to make sure they aren’t holding water and debris; Check and clean any new containers that you bring home that may contain water. Aedes aegypti eggs can remain viable under dry conditions for months.

As with all mosquito issues, native and non-native, the Butte County Mosquito and Vector Control District staff urges residents to take precautions to avoid mosquito bites by implementing the 4 Ds of protection:

Drain any standing water that may produce mosquitoes, this includes flowerpots, old tires, and buckets. Some species of mosquitoes can lay their eggs in very small sources of water, like a bottle cap; Defend yourself and your home by using an effective insect repellent and making sure screens on doors and windows are in good condition; Dusk or Dawn, avoid outside activities; Dress in long sleeves and pants when mosquitoes are active.
