From the County of Santa Clara

SANTA CLARA COUNTY, CALIF. – The County of Santa Clara Vector Control District has confirmed the presence of West Nile virus-positive mosquitoes in a small area of Cupertino (ZIP Code 95014). Weather permitting, this area will be treated to reduce adult mosquito populations with the use of truck-mounted equipment on Thursday, August 11, starting around 10 p.m., and concluding a few hours later.
The District’s mosquito management program largely focuses on preventing mosquitoes from reaching adulthood by proactively targeting immature stages of mosquitoes (eggs, larvae, and pupae). When a mosquito with West Nile Virus (WNV) is detected, however, the District takes the added step of conducting a mosquito control treatment to reduce the adult mosquito population in the area, which reduces the risk of a WNV-human infection.
