As a result, local mosquito control officials are expanding insecticide treatments. David Brown, who heads the Sacramento-Yolo Mosquito and Vector Control District, says crews are using hand sprayers and truck-mounted foggers. He says they won’t have to begin aerial spraying as long as they keep control of the mosquito population.
"Of course if we’re unable to do that or if conditions change to where it warms up dramatically and we see an increase in the adult mosquito population and the infection rates, we may have to consider aerial applications but we’re doing everything we can to try to avoid that."
Crews are spraying in various urban parks, including Carmichael Park and Hagan Park.
Brown urges residents to eliminate mosquito breeding sites by draining any standing water in their yards. And he recommends using insect repellent for people outdoors during dawn and dusk.
