Bed bug (likely shed skin or crushed specimen)

Bedrooms and other indoor resting areas, especially mattress seams, bed frames, upholstery, and wall cracks.

Feeds primarily on blood, usually human blood, using piercing-sucking mouthparts. It typically feeds at night while the host is resting.

Wingless, reddish-brown, nocturnal insects that hide in cracks during daylight. Females lay eggs in protected crevices, and populations can persist for months without feeding.

Bites commonly cause itchy welts, though bed bugs are not established vectors of disease. They provide no meaningful household or ecosystem benefit.
