(WKOW) — A familiar sound is back around Lake Winnebago.
Lake flies are hatching in swarms.
People who live on the north shore of the lake say they noticed the flies Saturday and they’ve gotten worse every day.
For many, the hardest part is keeping the flies out of their homes.
“We have an extra door in the house and we live like we’re in a submarine with an air lock you know,” said Mike Magnuson. “So you go in the first room and you completely de-fly and you’re safe to go in the house.”
The flies don’t live long, usually between one to two weeks.
They are good for the ecosystem. They’re a good food source for sturgeon and perch.
