[ARCHIVED] Recent Fogging for Mosquitoes Carrying West Nile Virus Deemed Successful


NOTE: The following information is from the San Mateo County Mosquito and Vector Control District and is being shared by the City of Menlo Park for the benefit of our residents.

The San Mateo County Mosquito and Vector Control District (SMCMVCD) fogging operations the night of August 11th successfully reduced mosquito populations in the 1300 acre treatment area in Menlo Park. Post-fogging mosquito samples tested negative and no future fogging is planned at this time.

The fogging was completed at approximately 2:30 am on Tuesday, August 12, 2014, and mosquito traps set before and after treatment showed an 86% reduction in the adult mosquito population after Monday night.

Maps of the fogging locations can be found on the District website, and residents with questions can call the District at (650) 344-8592 Monday through Friday from 8:00 am to 4:30 pm.

Reports of dead birds are an early indication that the virus is circulating in the environment. Residents are encouraged to help by reporting fresh carcasses of birds or tree squirrels to the West Nile virus hotline, online at or by phone at 877-WNV-BIRD (877-968-2473).
Physicians should be aware that residents in the fogging area may have come in contact with mosquitoes carrying WNV. If any of these residents come to the physician’s office with symptoms of WVN, they should be tested for the virus.

For assistance with a mosquito problem in San Mateo County, contact the District at (650) 344-85
