One hack that entomologists (a.k.a. insect experts) recommend? Switch out your light bulbs for LED lights—and pay close attention to the color.

Wait, why are some bugs attracted to light?

This is actually a question that’s still trying to be answered. “Nobody really knows for sure why some bugs are attracted to light,” says Howard Russell, M.S., an entomologist at Michigan State University.

Plus, “not all insects are attracted to light,” says Doug Webb, a board-certified entomologist and manager of technical services at Terminix International. The attraction to light is called phototaxis, he explains. Some bugs, like cockroaches, are actually repelled by light and thrive in the dark.
