Summer will arrive June 21st and already people are being buzzed and bitten by mosquitoes. Brendan Dunphy, an entomology researcher at Iowa State University, says he’s been studying the habits of these tiny flying pest for years and spotted his first mosquito of 2015 in Boone County back in March.

He urges people to police their yards to make it harder for mosquitoes to find a home.

Another recommendation is to wear long-sleeve shirts and use insect repellant when outdoors and staying indoors around dawn and dusk when mosquito activity is often the highest.
