Bed Bug (Fecal Staining)

Indoor environments, primarily in cracks and crevices near human sleeping areas such as mattresses, bed frames, and baseboards.

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans.

Nocturnal and elusive; they hide during the day and emerge at night to feed. The spotting shown is digested blood excreted after feeding, often found along travel paths or harborage sites.

Risks include itchy welts, allergic reactions, and psychological distress. While they do not known to transmit diseases, heavy infestations can cause anemia. There are no ecological benefits to humans.
