Bed Bug

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

Obligate hematophagous (feeds exclusively on the blood of warm-blooded animals, primarily humans).

Nocturnal and elusive; they emerge at night to feed and return to hiding spots. Their life cycle includes five nymphal stages, each requiring a blood meal to molt into the next stage.

Risks include itchy allergic reactions, skin rashes, and psychological distress. While they do not transmit pathogens directly to humans like mosquitoes, infestations are difficult and costly to eradicate. There are no known ecosystem benefits for humans.
