Scientists say it’s normal to see mosquitoes this time of year, but recent rain and flooding conditions are making it worse. W-S-A-W / T-V reports that entomologist P-J Liesch says weather patterns are what shape the mosquito season. Liesch says there are about 50-to-60 different species of mosquitoes in Wisconsin. He says some of those species rely on floodwaters from heavy rainfall to live. Liesch says getting heavy rain during the spring months means we could see some big mosquito populations in June. He says it’s too early right now to determine had bad the season will be.
