Behavior, Diet & Habits

Bed bugs only feed on blood. Under cool conditions, bed bugs have been able to survive up to a year without a meal. They prefer to be more active at night when the host is asleep.

Bed bugs are found in cracks and crevices, including mattress seams, sheets, furniture, behind baseboards, electrical outlet plates and picture frames. Often found in hotels, where they can travel from room to room and in visitors’ luggage or other personal belongings such as purses and briefcases.

Signs of a Bed Bug Infestation

Seeing the bugs. Adult bed bugs are about the shape and size of an apple seed.
Case skins. As the juvenile bugs grow, they shed their skins, discovery of which can indicate their presence.
Defecation. After feeding, bed bugs return to their harborage to hide where they defecate black to brown stains on porous surfaces or black to brown mounds on nonporous surfaces.
