Bed Bug

Human dwellings, specifically in cracks and crevices near sleeping areas (mattresses, bed frames, and headboards).

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. They undergo incomplete metamorphosis with five nymphal stages, each requiring a blood meal to molt.

Significant household pest; they do not transmit diseases but their bites can cause allergic reactions, skin rashes, and psychological distress. They provide no ecosystem benefits in human environments.
