Bed bug

Dwellings of humans and other warm-blooded animals, typically found in cracks, crevices, mattresses, and furniture near sleeping areas.

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

Mainly nocturnal; they emerge at night to feed and hide during the day. They progress through five nymphal stages, requiring a blood meal to molt at each stage before reaching adulthood.

Risks include skin rashes, psychological effects, and allergic symptoms from bites. While they do not transmit diseases, infestations cause significant stress and financial burden for eradication. They offer no known benefits to the human ecosystem.
