Researchers at Kansas State University say their research and a recent change in bedbug fumigation will make it cheaper to get rid of the pests.

A prepared statement from the university says bedbug infestations in the U.S. have grown and the bugs have developed a resistance to many insecticides.

Entomology professor Tom Phillips specializes in fumigant gases. He recently tested a sulfuryl fluoride known as Vikanea and found that it could be effective even at one-third of the rate of other products.

Phillips says his discovery means consumers will pay less money to get rid of bedbugs because less chemical is being used.
