Bed Bug

Primarily humans' dwellings, specifically in cracks and crevices near sleeping areas such as mattresses, bed frames, and headboards.

Obligate hematophages, feeding exclusively on the blood of warm-blooded animals, mainly humans.

Nocturnal insects that emerge at night to feed. They undergo incomplete metamorphosis with five nymphal stages, each requiring a blood meal to molt.

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 ecosystem benefits in human environments.
