for more information about the effectiveness of the treatment that occurred overnight on June 19th between 11:00 PM and 5:00 AM. This area was roughly bound by 4th Avenue and Poplar Avenue, El Camino Real and Highway 101.
As a precautionary measure the District will continue to test mosquitoes for WNV throughout the summer. If future treatment is needed, the District will provide advance warning, which the City will send to community members through social media, our website and a community alert.
Prevent the biting and breeding of mosquitoes
It wouldn't be summer without mosquitoes. Usually their mildly annoying bite creates a tiny bump and a couple days of scratching. But, they are also carriers of the West Nile Virus, which can be found in dead birds, squirrels and other small animals. While these cases are rare in San Mateo and throughout the Bay Area, it’s important to know what you can do to prevent mosquitoes from biting and breeding around your home.
Follow the “Three D’s”
as outlined by the San Mateo County Mosquito and Vector Control District (SMCMVCD).
DRAIN – Mosquitoes lay their eggs in standing water. Eliminate all sources of standing water on your property, including flower pots, old car tires, rain gutters and pet bowls.
DAWN & DUSK – Mosquitoes bite in the early morning and evening. It is important to wear proper clothing and repellent if outside during these times. Make sure that your doors and windows have tight fitting screens to keep mosquitoes out.
DEET – Apply insect repellent containing DEET, picaradin, oil of lemon eucalyptus or IR3535 according to label instructions. Repellents keep the mosquitos from biting you. DEET can be used safely on infants and children 2 months of age and older.
Help Control Mosquitoes
If you should notice an abundance of mosquitoes on or near your property, are experiencing more mosquito bites or notice the carcass of a bird or squirrel, please report it to the West Nile Virus hotline either online at www.westnile.ca.gov or by calling 877-WNV-BIRD (877-968-2473).
The City of San Mateo and the County Mosquito and Vector District encourage residents to help control mosquitoes and prevent the spread of the West Nile Virus. Taking the time to report these instances is a proactive preventative measure to take. And, it will help to ensure that the San Mateo community can safely enjoy their summer!
