Bed Bug

Dwellings, especially beds and bedding, furniture creases, cracks in walls, and other sheltered locations close to hosts.

Strictly hematophagous (blood-feeding), primarily on human blood. They feed mostly at night.

Nocturnal feeders, hiding in cracks and crevices during the day. They are attracted to warmth and carbon dioxide. They aggregate in harborage areas and leave fecal spots (digested blood) on surfaces.

Potential risks include itchy red welts from bites, allergic reactions, and secondary skin infections from scratching. They are not known to transmit diseases to humans. There are no direct benefits of bed bugs to humans or the ecosystem.
