2014.06.04-Fogging to Suppress West Nile Virus Mosquitoes in Areas of Santa Clara, Sunnyvale, and Cupertino

Published on: 8/11/2016 11:59 AM

Ground fogging operations to suppress WNV-carrying adult mosquitoes in the 95051, 94096, 94087, and 95014 ZIP code areas of the cities of Santa Clara, Sunnyvale, and Cupertino were completed at approximately 2:00 a.m. on Thursday, June 05, 2014. 

All post-fogging mosquito samples were negative for WNV.

SAN JOSÉ, CALIF. –The Santa Clara County Vector Control District (SCCVCD) confirmed on May 29 that adult mosquitoes collected from the 95051, 94096, 94087, and 95014 ZIP code areas tested positive for West Nile virus (WNV).  The detection of mosquitoes infected with WNV has prompted the scheduling of a mosquito fogging treatment in the surrounding area, in an effort to prevent human cases of WNV.  Weather permitting; the ground fogging is scheduled for Wednesday, June 4 at 11:00 pm, and is planned to last for several hours. 


The fogging area is generally bordered by Maria Ln., Ponderosa Ave., Lupine Dr., Lily Ave., and Cabrillo Ave. on the north; N. Wolfe Rd., Hummingbird Ln., Grackle Way, and Kingfisher Way on the west, Townsend Av., Calabazas Blvd., Alpine Ave., Peppertree Ln., and Pruneridge Ave. on the south.

Information packets will be distributed in the fogging area beginning on Saturday May 31, notifying residents about the fogging operation.  As an added convenience, on Tuesday and Wednesday, staff from the Santa Clara County Vector Control District and the Public Health Department will be available during extended hours from 7:30 am to 7 pm via a dedicated phone line/voicemail (800-314-2427) to answer questions and provide information.  

Post-fogging mosquito samples will be set on Thursday, and collected on Friday, June 6. If virus is found in the post-treatment samples, additional fogging may be required. If no virus is found, further fogging will not be needed.
