Invasive Aedes aegypti mosquito found in North Fair Oaks
The San Mateo County Mosquito and Vector Control District has recently detected invasive Aedes aegypti mosquitoes in North Fair Oaks. The District is checking properties in the area to determine how widespread the Aedes aegypti mosquitoes are in the area.
Aedes aegypti are small (about ¼ inch) black and white mosquitoes that bite aggressively during the day. They are an invasive species not native to California, but they have become established throughout the United States, including in many California counties. Aedes aegypti mosquitoes can potentially spread several diseases, including dengue, chikungunya, Zika, and yellow fever. At this time, the risk of Aedes aegypti spreading disease in San Mateo County is very low.
“Our staff need only a few minutes to check around the yard for water where mosquitoes can grow. Neighbors who welcome us to visit their properties help us be as efficient as possible. Our goal is to keep these dangerous mosquitoes from spreading throughout the area,” said Operations Director Casey Stevenson.
