Bed Bug

Dwellings, especially beds, mattresses, bed frames, and furniture; preferring cracks and crevices near human sleeping areas.

Strictly hematophagous, feeding on the blood of humans and other warm-blooded animals.

Nocturnal feeders, emerging from hiding spots to feed on resting hosts. Bites often appear in lines or clusters (breakfast, lunch, and dinner pattern). Highly resilient; can survive for months without a blood meal.

Potential risks include itchy red welts, allergic reactions, secondary skin infections from scratching, and psychological distress. While primarily a nuisance, they are not known to transmit diseases to humans. No known benefits to the ecosystem.
