Insect experts in Ohio say their genetic study of bedbugs reveals that the pests are evolving to survive the main pesticides currently used to combat them.

Writing in the online journal PLoS One, Ohio State University entomologists found that bedbugs are undergoing genetic changes that help protect their nerve cells from specific pesticides.

“We're dealing with a different bug than what we were decades ago,” said the university’s urban entomologist Susan Jones.

University of Massachusetts in Amherst researchers recently found that bedbugs in New York City are now 250 times more resistant to standard pesticides than those in Florida.

The resistance has become such a problem that exterminators are now forced to heat infected rooms to above 111 degrees Fahrenheit to successfully eradicate the biters.
