Cimicid Bed Bug (Remnant)

Natural Habitat

Typically found in urban living environments, specifically in cracks of furniture, bedding, and baseboards within close proximity to human sleeping areas.

Diet & Feeding

Obligate hematophages, meaning they feed exclusively on the blood of vertebrates, primarily humans.

Behavior Patterns

Nocturnal and elusive; they hide during the day and emerge at night to feed. They go through five nymphal stages, requiring a blood meal to molt between each stage.

Risks & Benefits

While not known to transmit diseases, they cause significant psychological distress, sleep deprivation, and reddish, itchy welts from allergic reactions to their saliva. They offer no ecosystem benefits in domestic settings.
