Bed Bug

Human dwellings, specifically in and around beds, mattresses, bed frames, and crevices in furniture or walls.

Obligate hematophages, primarily feeding on human blood, though they may also feed on other warm-blooded animals.

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult).

Risks include physical reactions like itchy welts, skin infections from scratching, and psychological distress. They are not known to transmit diseases to humans. There are no ecological benefits to humans.
