Found indoors, primarily in crevices of mattresses, bed frames, furniture, and baseboards close to human sleeping areas.

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

Nocturnal parasites that hide during daylight hours and emerge at night to pierce skin and feed. They undergo incomplete metamorphosis through five nymphal stages.
