Bed Bug (Infestation Sign)

Human dwellings, specifically cracks and crevices near sleeping areas such as mattresses, bed frames, and furniture.

Obligatory hematophagous; 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 image shows dark spots which are typical fecal spotting (digested blood) left on linens.

Risks include allergic reactions to bites, secondary skin infections from scratching, and significant psychological distress; they are not known to transmit diseases to humans.
