Bed Bug

Found globally in human dwellings, typically hiding in cracks, crevices, mattress seams, and bed frames near their host's 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 and then return to hiding. They go through five nymphal stages before reaching adulthood, requiring a blood meal to molt at each stage.

Risks include itchy skin rashes, psychological distress, and potential allergic reactions to bites. They are not known to transmit diseases to humans. They offer no known ecological benefits in human environments.
