In brief
New research indicates that the relationship between bedbugs and humans dates back approximately 245,000 years. Bedbugs evolved from bat parasites to thrive in human habitats, especially as people settled in urban environments about 13,000 years ago. The insect, while a nuisance, does not pose any disease threat to humans.
New research has unveiled a surprisingly ancient relationship between bedbugs and humans, suggesting that these notorious pests have been closely linked to our kind for around 245,000 years. The findings indicate that bedbugs, once exclusively feeding on bats, made a significant leap when they began to feed on early humans, likely during shared habitation in caves.This transition marks the split between two species of bedbugs: one that continued to rely on bat blood, and another that became dedicated to human sustenance. Warren Booth, professor of urban entomology at Virginia Tech and the study’s lead author, emphasizes that bedbugs are entirely dependent on human hosts for survival; you won't find them thriving in rural settings.After a decline linked to early humanity's nomadic lifestyle, the population of human-dependent bedbugs surged around 13,000 years ago, coinciding with the establishment of permanent settlements. Scientists highlight that despite the discomfort they cause through bites, bedbugs do not carry diseases—a fact that might provide some solace to those troubled by their presence. As urban centers continue to spread, bedbugs remain a testament to an enduring and uninvited companionship with humans through the ages.
