Specifically, bed bugs are very, very hard to kill once they infest something like a mattress. When they are dormant, they're almost invisible and almost indestructible. There is no effective way to remove an infestation from a mattress that doesn't either destroy the mattress or involve very toxic and/or illegal chemicals. (DDT was really the only effective pesticide for them, but that turned out to also really fuck up ecosystems, so we banned it)
