Targeted adult mosquito control treatment scheduled for Thursday, June 30 in a limited area within Milpitas
SANTA CLARA COUNTY, CALIF. – The County of Santa Clara Vector Control District has confirmed the presence of West Nile virus (WNV) positive mosquitoes in an area of Milpitas (ZIP Code 95035). Weather permitting, this area will be treated to reduce adult mosquito populations with the use of truck-mounted equipment on Thursday, June 30, starting around 10 p.m., and will conclude a few hours later.
The Vector Control District has a dedicated surveillance program to detect the presence of diseases like West Nile virus, St. Louis encephalitis, and western equine encephalitis, all of which are transmitted through the bite of infected mosquitoes. The data collected through surveillance is used to predict locations that are more likely to have these disease-transmitting mosquitoes. When a WNV-positive mosquito is detected, the District initiates an adult mosquito control treatment to reduce the mosquito population in the area, which reduces the risk of a WNV human infection.
The District has been conducting truck-mounted treatments regularly since 2003 to successfully reduce WNV-transmitting mosquito populations. The District will be adhering to requirements and recommendations from the County of Santa Clara Public Health Department for COVID-19.
