Bed bug

Found exclusively in indoor environments, infesting mattresses, box springs, bed frames, and furniture crevices near human resting areas.

Obligate hematophages that feed exclusively on the blood of humans and other warm-blooded animals.

Nocturnal and highly secretive, hiding in tight cracks during the day and emerging at night to feed via a piercing-sucking mouthpart.

Their bites cause localized skin irritation, allergic reactions, and significant psychological distress; they provide no ecological benefit to humans.
