Bed Bug Fecal Spotting

Indoor environments, primarily near human sleeping areas such as mattresses, bed frames, seams of fabric, and curtains.

Obligate hematophagous (blood-feeders), primarily on human blood.

Nocturnal parasites that hide in tight crevices during the day. These dark spots are digested blood excreted as waste on surfaces like bed sheets or walls.

Risks include itchy allergic reactions to bites and psychological distress; they do not transmit diseases but are a significant pest nuisance.
