ROSEVILLE, JUNE 13, 2023 –  The Placer Mosquito and Vector Control District detected an invasive Aedes aegypti mosquito in Roseville today. The Aedes aegypti mosquito, commonly known as the yellow fever mosquito, was found in the Cherry Glen neighborhood of Roseville.

Aedes aegypti mosquitoes have been spreading throughout California since 2013. This mosquito is small with black and white striped legs and a white violin-shaped marking on its back. Aedes aegypti can transmit several viruses, including Zika, dengue, chikungunya and yellow fever. These viruses, however, have not been found circulating in California.

Placer Mosquito will follow its invasive mosquito response plan to determine the extent of the infestation. The District will need residents to help by allowing our technicians to access and inspect front and back yards of nearby properties to the Cherry Glen neighborhood.
