“This is something that people have suspected, but it’s really nice to have it in black and white,” Christiane Weirauch, a systematic entomologist at the University of California, Riverside, who was not involved in the new study, tells Science. Aside from pushing the date of the first bedbug bite back millions of years, the study also gives clues about the insect’s encounters with humans.
