Neighborhood and surrounding areas to be sprayed with mosquito pesticide Wednesday

Santa Clara County officials plan to spray insecticides in parts of San Jose and unincorporated areas of Santa Clara County next week after finding mosquitoes that tested positive for the West Nile virus in the area.

Those living in the 95127 and 95140 zip code area east of Alum Rock, centered around Calco Creek Drive, may see trucks driving around the area around 10pm that night, spraying insecticide to reduce adult mosquito populations, weather permitting. Spraying will last two to four hours.

This is the first West Nile Virus treatment conducted in the county this year. This type of treatment has been conducted periodically since 2003 to reduce the population of mosquitoes infected with West Nile Virus.

According to the county, adult mosquitoes are the primary vectors of vector-borne viruses that cause disease in humans, and treatments to control adult mosquitoes are intended to reduce the mosquito population in the area and reduce the risk of West Nile virus infection to humans.
