Study Shows Widespread Resistance in Nation’s Bed Bug Populations to Pyrethroid

The University of Kentucky announced that a bed bug study which included 110 bed bug populations from across the nation showed that 88 percent of the populations included one or two genetic knockdown resistance (kdr-type) mutations to synthetic pyrethroid pesticides. Knockdown resistance mutations, means that the insecticide pyrethroid can’t kill bed bugs that have this type of mutation.

One of the entomologists involved in the study stated that we need alternative insecticides to fight bed bugs. New York City and New Jersey residents are probably tired of fighting bed bugs and would prefer bed bugs stop eating human blood and find another food source. 

All the New York City bed bug populations tested in the study had one or both mutations for pyrethroid resistance. Pyrethroid chemicals are used by some pest control companies to kill bed bugs. Reports from many pest control companies indicate that pyrethroid products are not performing as well at killing bed bugs as they would like.

It’s important to catch a bed bug infestation early, thus bed bug monitors can be a valuable part of a bed bug plan.
