Bed Bug (First-Stage Nymph)

Human dwellings, specifically in cracks, crevices, mattresses, and bed frames near sleeping hosts.

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans.

Nocturnal and elusive; they hide during the day and emerge at night to feed. Nymphs require a blood meal to molt into the next life stage.

Risks include itchy skin welts, allergic reactions, secondary skin infections from scratching, and psychological distress. They are not known to transmit diseases to humans.
