Natural Habitat

Found indoors in residential and commercial settings, particularly within cracks and crevices of bed frames, mattresses, and furniture.

Diet & Feeding

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

Behavior Patterns

They are nocturnal, emerging at night to feed. After a blood meal, they may leave behind small reddish-brown fecal spots or blood stains on linens, similar to the mark shown in the image.

Risks & Benefits

While not known to transmit diseases, they cause itchy welts, allergic reactions, and significant psychological distress; they provide no known ecosystem benefits in human environments.
