MILPITAS (BCN) — A portion of Milpitas will be sprayed with insecticide Saturday night after the Santa Clara County Vector Control District confirmed the presence of mosquitoes that tested positive for West Nile virus, the vector district announced Friday. The spraying will take place in ZIP code 95035, centered at Gingerwood and Aspenridge drives, starting at 10 p.m. Saturday and lasting for a few hours, vector district officials said.

Residents will not have to relocate during the treatment, which poses minimal risk to people, pets, animals and the environment, though those who would like to take extra precautions can keep family and pets inside during the ultra-low volume spraying, according to the district. Residents in the area are being notified by the county’s AlertSCC system as well as on Nextdoor and other social media sites.

Since the virus came to California in 2003, 7,474 people across the state have gotten the virus and 359 of those cases were fatal, vector district officials said. District staff can answer any questions by phone from 7:30 a.m. to 4 p.m. on weekdays on a dedicated West Nile virus hotline at (408) 282-3114 or by email at
