Bed Bug (Nymph phase)

Domestic environments, specifically beds, furniture, and cracks/crevices near sleeping areas.

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: They are significant household pests that cause itchy welts, allergic reactions, and psychological distress. Unlike many other blood-sucking insects, they are not known to transmit diseases to humans. Benefits: None.
