Gary Goodman is with the Sacramento - Yolo Mosquito Vector Control District.
He says they don’t usually find mosquitoes with the virus this early in the year.
“And so, the fact that Contra Costa has a number of positive pools already is definitely a cause for concern and that’s why we want to make sure that people are draining standing water, putting on a good repellent and making sure that they’re avoiding getting bitten by mosquitoes.”
Goodman says foreclosed homes with neglected spas and swimming pools continue to be a problem. Last year, crews found over two-thousand pools producing mosquitoes.
On Tuesday, mosquito control workers will be handing out repellent at several local homeless shelters as part of Mosquito and West Nile Virus Awareness Week.
