Rain, humidity lead to an increase in mosquitoes in southern Wisconsin

“This summer, all those mosquitoes that were waiting in the ground for water have found it,” says Dr. Lyric Bartholomay, who works in the Department of Pathobiological Sciences at UW-Madison. “So, the nonstop rain that we’ve had, and the warm temperatures just make them for the perfect storm, for the mosquitoes to have a place to grow and reproduce. And then come out hungry to feed on us.”
