    BRENTWOOD, CA - AUGUST 23: Technicians with the Contra Costa County Mosquito and Vector Control District drive a truck through a neighborhood fogging with Pyrocide 7396 insecticide on August 23, 2012 in Brentwood, California. In the wake of the largest outbreak of the West Nile Virus in the U.S. history, the Contra Costa County Mosquito and Vector Control is fogging areas of the county that have seen a spike in numbers of mosquitoes carrying the West Nile Virus. More than 1,100 people in the Unites States have been infected with West Nile and 41 people have died. (Photo by Justin Sullivan/Getty Images)

    There's a mosquito problem in the Bay Area, and counties are fighting back with more fogging in neighborhoods Tuesday night.

    The Contra Costa County Mosquito and Vector Control District will conduct ground fogging starting at 7:35 p.m. Fogging trucks will be out on Holland Tract in Knightsen to prevent the spread of the West Nile Virus.

    Fogging will also take place in Los Altos and Mountain View. Health officials say mosquitoes there tested positive for the West Nile Virus as recently as last week. The fogging area is bordered by Villa Street and Escuela Avenue on the north; Clark Avenue, Verano Drive, North Gordon Way, South El Monte Avenue and Campbell Avenue on the west; State Highway 85 and Sun Mor Avenue on the east; and Covington Road and Levin Avenue on the South.

    Fogging in that region is set to begin at 11 p.m.
