Bed bug

Homes and other indoor spaces, especially in mattress seams, furniture, and carpet edges.

Feeds on blood, mainly from humans; typically feeds at night.

Flat, reddish-brown, wingless insects that hide in crevices and can survive for months between meals. The image appears consistent with a bed bug.

Bites can cause itchy skin reactions and disturbed sleep; bed bugs are not known to transmit disease. They offer no meaningful household benefit.
