Late-blooming mosquitoes have brought misery. Cooler temperatures could bring relief

Quoted: PJ Liesch, a University of Wisconsin-Madison entomologist, said he started getting calls from folks in August. Most were from eastern parts of the state, but he also heard from people in Stevens Point and Wausau.

Some of the worst swarms have been “floodwater” mosquitoes.

“They’re very good at taking advantage of temporary pools of water,” Liesch said. “The eggs are always present in low-lying areas and can sit there for months, even a couple of years, waiting for the rain to come. Once they hatch, those mosquitoes turn into adults very quickly.”
