Bed Bug

Found globally in human dwellings, typically hiding in mattress seams, bed frames, furniture, and cracks or crevices near sleeping areas.

Obligate hematophages, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans.

Mainly nocturnal; they emerge at night to feed. They undergo hemimetabolous metamorphosis across five nymphal stages, requiring a blood meal to advance to the next stage.

Risks include itchy red welts, allergic reactions, and psychological distress/insomnia. They are not known to transmit diseases to humans. There are no known benefits to the ecosystem or humans.
