Bed bug

Found exclusively indoors, primarily in mattresses, bed frames, furniture cracks, and dark crevices near sleeping areas.

Obligate hematophagous ectoparasites that feed exclusively on the blood of humans and other warm-blooded animals.

Nocturnal and highly secretive, emerging mainly at night to pierce skin and feed while hosts sleep. They hide tightly clustered in harborages during the day.

Bites cause itchy, red welts and severe psychological stress due to persistent infestations. They provide no ecological benefits to humans.
