Santa Clara County Mosquito and Vector Control District will conduct a mosquito control treatment Tuesday night after mosquitoes infected with West Nile virus were detected in parts of Santa Clara.

The treatment is scheduled to begin at about 10 p.m. Tuesday and is expected to last no more than four hours, city officials said.

It will target areas in ZIP codes 95050, 95051, 95117, 95126 and 95128.

City officials said the localized treatment will use truck-mounted equipment to apply an ultra-low-volume insecticide aimed at reducing adult mosquitoes capable of spreading West Nile virus through their bites.

The city said the treatment is intended to lower the risk of human infection and noted that the schedule could change depending on conditions.
