One of the most of the most widely used commercial chemicals to kill bedbugs are not effective because the pesky insects have built up a tolerance to them, according to a team of researchers from Virginia Tech and New Mexico State University.
Millions of dollars have been spent on insecticides to kill the bugs that have wreaked havoc on everything from hotels in New York City to homes in Los Angeles. But this is the first study to show that overuse of certain insecticides has led to an increased resistance to the compounds, making them much less effective than advertised.
