Bed bug (nymph)

Indoor domestic environments, specifically hiding in mattresses, box springs, crevices, and furniture near sleeping areas.

Obligate hematophage, feeding exclusively on the blood of humans and other warm-blooded animals.

Nocturnal and highly secretive, emerging primarily at night to pierce skin and feed before retreating to dark harborage sites.

Causes itchy, irritating bites and psychological stress, but transmits no known human pathogens; provides no ecological benefits in human habitations.
