Flying Cockroaches! Heat Sends Your Favorite Pests Soaring

Summer weather can make for hot, sticky and uncomfortable days. And if staying cool and keeping hydrated aren't enough to worry about, heat waves could cause cockroaches to take to the skies. Yes, you read that right. Flying cockroaches.

"Cockroaches, like all insects, are cold-blooded, meaning their activity rate increases with temperature," said Jules Silverman, an entomologist and professor at North Carolina State University, in an interview with Live Science. (Cold-blooded creatures are ectothermic, which means they depend on external heat to keep their bodies warm.)

This also means that the species of cockroach that are able to fly (and most of them are capable) are probably more likely to do so in warmer places, said Silverman.

If you think that flying cockroaches are especially horrific, you probably live somewhere with a colder climate and a denser human population. Flying cockroaches in the subways of New York have garnered some headlines, but "flight of the cockroach" is not so common up north, said Michael Bentley, staff entomologist for the National Pest Management Association. People in the southern states are likely to miss what all of the fuss is about. "Down in Florida, they fly a lot more," Bentley told Live Science. "They have to cover a greater distance to find food."
