After an active spring, the native mosquito populations
are naturally declining. But not the Asian tiger mosquito.
A rainy March and April kept mosquito slappers busy.
“We had populations in larger numbers than expected this spring,” says Mike Cantwell, chief of Maryland Department of Agriculture’s Mosquito Control Program. “High rainfall brought out exceptionally large broods of woodland species. But these are single-generation species. Once they’re done, you don’t see them until next year.”
