Bedbugs are wingless, reddish-brown insects about 3/16 of an inch long. They’re called bedbugs because they often live in beds and mattresses, and come out at night to bite sleeping people.
During the day, bedbugs may hide in the folds of a mattress, in cracks in a bedstead, beneath loose wallpaper, or wherever else they can find shelter.
But at night, these pests emerge from hiding to seek their food, human blood! After biting a person or an animal, they retreat to their hiding places, and may take days to digest a meal.
