As EPA hosted its second annual National Bed Bug Summit in Washington, D.C. this week, evidence continues to mount that bed bugs are increasingly immune to the pesticides being used to control them.
Bed bugs are providing a textbook example of how pests become resistant to pesticides. According to researchers at Ohio State University, when pesticides are applied to bed bug colonies, inevitably a small population survives and develops resistance to the chemical used. As these survivors reproduce, they pass on that resistance to their offspring, creating new generations of pesticide-resistant bed bugs.
