Bed Bug (Nymph)

Human dwellings, specifically cracks and crevices near sleeping areas such as mattresses, bed frames, and upholstered furniture.

Obligate hematophagy (feeds exclusively on blood, primarily from humans).

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 a significant household pest.
