Bed Bug

Human dwellings, specifically tucked into mattress seams, bed frames, headboards, and cracks or crevices near sleeping areas.

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

Nocturnal and elusive; they emerge from hiding at night to feed. After a blood meal, they return to harborages to digest and mate. They undergo incomplete metamorphosis (egg, nymph, adult).

Risks include itchy welts, allergic reactions, and significant psychological distress or insomnia. While not known to transmit diseases, they are a major nuisance pest. There are no known benefits to the ecosystem or humans.
