Bed bugs are active only at night, usually just before dawn. During the day, they hide in cracks and crevices in walls, floors, beds, and furniture. When only a few bed bugs are present, they live close to human sleeping areas; when numerous, they can be found in many rooms of the house. A characteristic “bed bug odor” is frequently present in a home infested with bed bugs.
