Bed bug

Homes and other indoor spaces, hiding in mattress seams, furniture, and cracks near sleeping areas.

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

Flat, reddish-brown, wingless insects that hide by day and usually feed at night; females lay eggs in sheltered crevices.

Bites can cause itchy skin reactions and infestations are difficult to eliminate; bed bugs are not known to transmit human diseases.
