Bed Bug (nymph and adult debris)

Human dwellings, specifically cracks and crevices around beds, mattresses, headboards, and upholstered furniture.

Obligate hematophagy; 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. They undergo incomplete metamorphosis (5 nymphal stages) and require a blood meal to molt to the next stage.

Risks include itchy allergic reactions to bites, sleep deprivation, and psychological distress. While not known to transmit diseases to humans, they are a significant pest. No known ecosystem benefits in a domestic human environment.
