As "nest parasites," bedbugs haven't had much trouble following us over the millennia from caves and huts to houses and hotels. They hide in dark, secluded areas during the day — in mattresses, behind walls, under floors — and come out at night to drink blood. An outbreak can spread quickly, since females lay up to five eggs a day and 500 in a lifetime.
