Bed Bug (Nymph)

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

Obligate hematophages, meaning 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. They undergo incomplete metamorphosis (hemimetabolous) through five nymphal stages, requiring a blood meal to molt to the next stage.

Risks include itchy welts, allergic reactions, and psychological distress. While they do not transmit diseases, infestations are difficult and costly to eradicate. They provide no known ecological benefits in human environments.
