It's a good news/bad news situation. More snow pack means more cold, moving water later in the year. But the late rains also mean more small pools of stagnant water are now providing perfect breeding grounds for mosquitoes. Luz Maria Rodriguez is with Sacramento-Yolo Mosquito and Vector Control District. She says conservation efforts do a lot to keep the population down.
RODRIGUEZ: "People have a tendency not to conserve as much, so that means they may over-water their garden or over-water their lawn or wash their car and they are not as careful. If there's more water, of course, that's a big concern of the district because there's more probabilities that the mosquitoes will breed.
The District has not seen enough mosquitoes yet to know if aerial spraying will be needed. Rodriguez says people spraying insect repellant before heading out can do a lot to keep the threat of West Nile to a minimum. The district has not seen a West Nile case since March.
