The Santa Clara County Vector Control District is scheduled to do a mosquito fogging treatment on Tuesday, June 24 at 11 p.m.
The ground fogging, which will include spraying a fine mist of pesticides, will be conducted in parts of Sunnyvale, Mountain View, Los Altos and Cupertino. The exact area is bordered by Lynn Way, Cambridge Avenue, Brookline Drive and Hyde Park Drive on the north; Tilton Drive and Yukon Drive on the east; West Homestead Road on the south; and Alford Avenue, Park Hills Avenue and Wessex Avenue on the west.
The fogging is expected to last several hours, and is centered at St. Mary and Fremont Avenues. Only one pesticide -- Zenivex -- will be used.
The fogging plans were prompted by a confirmation on June 17 from the Vector Control District that adult mosquitoes in the area tested positive for West Nile virus, according to a press release by the county's Public Affairs Office.
West Nile virus causes mild to severe flu-like symptoms, like fevers and aches, and in some severe causes can cause neurological damage and death. The elderly are most susceptible to catching the virus, and since 2003, over 4,000 people have contracted the disease in California. Of those cases, 145 were fatal.
According to the manager of the Vector Control District, West Nile virus activity is very high, and residents should avoid mosquito bites throughout the county.
Information packets will be distributed Friday to notify residents in the fogging area. Staff will be available to answer questions from 7:30 a.m. to 7 p.m. via phone at 800-314-2427.
