Bed Bug

Indoor environments, specifically cracks and crevices near human sleeping areas such as mattresses, bed frames, and baseboards.

Obligate hematophagous (blood-feeders), primarily targeting humans but also feeding 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 itchy skin welts, allergic reactions, insomnia, and psychological distress. They are not known to transmit diseases but are significant household pests.
