Even David Attenborough's cotton voice couldn't make this one sound any less terrifying. As if bedbugs weren't ghastly enough; feeding upon sleeping humans in the comfort of our own beds... their mating habits open up a whole new world of horror. "Traumatic insemination", as it's nauseatingly known as, is the reproductive act in which a male bedbug stabs the female's abdomen with his super-sharp penis; injecting his sperm through the wound directly into her abdominal cavity. It then diffuses to her ovaries, and voila - the disturbing mating ritual is complete. Not disturbing enough for you? In some cases, these bedbugs will attempt to mate with other males; piercing their abdomen with their reproductive spear. Maybe they're homosexual, maybe they're just stupid - but the violated males often die after being punctured, since they don't have the defensive cells that females do. Freaked out enough yet?
