Fears about West Nile-infected mosquitoes in San Mateo County are in the air since a squirrel, which is unlikely to have traveled very far, was confirmed to be carrying the virus.

All the April showers — followed by May and June showers — we’ve had this year have been great for aquifers, river ecosystems and farmers.
Unfortunately, they’ve also been great for mosquitoes.
Mosquito abatement teams in San Francisco and the Peninsula are reporting more of the pests in marshes, pools and other standing bodies of water thanks to heavy rains that came late in the season and were often followed by warm fronts.
The start of West Nile virus season was marked by the county’s first reported case of the rare but potentially fatal human disease this year in a dead bird found in the Industrial City.
The dead bird was found by a resident in South San Francisco on May 15 and was taken by authorities to the California Department of Health Services. The state agency determined Wednesday that the bird died from the West Nile virus, officials said.
First let me state that my primary responsibility as your Mayor is to keep you safe. Your City Council has made a decision that may not seem fair to some but it was the right decision.
Our City is kept dry by the excellent condition of our levees. It was brought to our attention several months ago that the ground squirrel burrows along our levee, which range anywhere from five to 30 feet in length and between two to four feet below the soil surface, could compromise the integrity of our levee infrastructure.
Guardian chickens, mineral oil and animal testing are all being used this summer to prevent an increase in mosquitoes in San Mateo County, after South Bay cities experienced a surge in possible carriers of the West Nile virus.

Local mosquito experts confirmed a squirrel collected earlier this month in the city of San Mateo was positive for the West Nile virus which in itself isn’t dangerous for humans but implies the presence of infected mosquitoes.
That implication is leading health officials to urge people to take precautions against the potentially fatal virus, such as wearing mosquito repellent and removing standing water from property.
There’s no need to guess at the origin of the litter that flows into San Mateo Creek. It’s not hard to recognize.
