State officials say the high heat may either shrink or enhance Indiana's mosquito population.

Purdue associate professor Catherine Hill says it‘s hard to predict, but the heat will likely be too much for some of the state’s mosquitos.

“The mosquitoes are a bit like you and I,” she said. “They like to stay out of the heat, so they rest during the day. Typically, they rest underneath bushes, in the grass, particularly if you have tall or long grass. You‘ll find them in shaded areas.”

Mosquitoes already on the prowl will usually wait until it cools off to eat. She says the heat could have the opposite affect on wet areas, creating ideal conditions for mosquitoes to breed.
