Bed Bug

Cracks and crevices near sleeping areas, including mattresses, bed frames, and behind wallpaper in residential and lodging environments.

Obligate hematophagy (feeds exclusively on the blood of warm-blooded animals, primarily humans).

Nocturnal, identifying hosts by body heat and carbon dioxide; they undergo incomplete metamorphosis through five nymphal stages, requiring a blood meal to molt.

Risks include itchy welts, allergic reactions, and psychological distress; they do not transmit diseases to humans but are considered a significant household pest. There are no ecological benefits to humans.
