Northern California’s wet winter left plenty of places for mosquitoes to breed and hatch in late April and May, according to public health and agricultural experts. That means North State residents will likely be smacking more of them than during the past three springs and summers. But with a bit of cleaning up and a few lifestyle changes, people can make it harder for mosquitoes to bite them or inhabit their yard. Three years of drought left the insects fewer wet places to breed last spring. That changed this year, with the heavy rain and snowmelt that filled waterways, according to the Shasta Mosquito and Vector Control District.
