San Mateo County mosquito officials will fog again in North Central San Mateo Monday night because West Nile Virus remains after the last treatment.
Adult mosquitos collected July 24 after the July 21 fogging in the 94401 zip code tested positive for the virus, according to the San Mateo County Mosquito and Vector Control District.
The planning fogging in a half-mile radius around the detection site is scheduled between 9 p.m. and 5 a.m. Monday, July 28 through the next morning.
This marks the first year mosquitos carrying the West Nile Virus have been found in San Mateo County, according to District Manager Robert Gay.
Residents with questions about the fogging should contact the district from 8 a.m. to 5 p.m. Monday through Friday at 344-8592.
Dead birds and squirrels — early indications of the virus — should be reported online at www.westnile.ca.gov or by calling 877-WNV-BIRD (877-968-2473).
