Bed Bug

Primarily indoors within human dwellings, hiding in mattress seams, bed frames, and cracks near sleeping areas.

Hematophagous (blood-feeding); primarily feeds on human blood at night.

Nocturnal and elusive; they hide during the day and are attracted to heat and carbon dioxide emitted by hosts. They undergo incomplete metamorphosis (egg, nymph, adult).

While not known to transmit diseases, they cause itchy red welts, allergic reactions, and significant psychological distress; they are considered a major domestic pest.
