Bed Bug

Found worldwide, primarily located indoors in cracks and crevices near human sleeping areas, mattresses, bed frames, and behind headboards.

Hematophagous (feed exclusively on the blood of warm-blooded animals), preferentially humans.

Nocturnal and generally cryptic, hiding during the day in tight clusters; they are attracted to the carbon dioxide and warmth of their hosts.

Primary risk is nuisance biting which causes itching, allergic reactions, and sleep loss; they can cause significant psychological stress but are not definitively known to transmit disease.
