Natural Habitat

Indoor environments, specifically in proximity to sleeping areas, including mattresses, bed frames, furniture, and cracks/crevices in walls.

Diet & Feeding

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

Behavior Patterns

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo five nymphal stages, requiring a blood meal to molt into the next stage.

Risks & Benefits

Risks include itchy skin welts, allergic reactions, and psychological distress/insomnia. They are highly resilient pests that require professional extermination; they offer no known ecosystem benefits in human dwellings.
