Natural Habitat

Human dwellings, especially mattresses, upholstered furniture, clothing, and cracks near sleeping areas.

Diet & Feeding

Feeds almost exclusively on blood, mainly from humans, using piercing-sucking mouthparts.

Behavior Patterns

Mostly nocturnal and hide in seams or crevices during daylight. They can survive months without feeding and spread by hitchhiking in luggage, clothing, and furniture.

Risks & Benefits

Bites cause itchy, inflamed welts and can trigger allergic reactions, but bed bugs are not known to transmit disease routinely. They provide no meaningful household benefit.
