Bed bug

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

Obligate hematophagous insects that feed exclusively on the blood of warm-blooded animals, primarily humans.

Nocturnal parasites that emerge at night to feed. They undergo hemimetabolous metamorphosis consisting of five nymphal stages, each requiring a blood meal to molt.

While not known to transmit diseases, their bites cause intense itching, allergic reactions, and psychological distress. They are considered a significant public health pest.
