Bed Bug

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

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

Mainly nocturnal; they emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to molt into the next stage.

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