Natural Habitat

Indoor environments, primarily residing in cracks and crevices of mattresses, bed frames, furniture, and behind baseboards in proximity to human sleeping areas.

Diet & Feeding

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

Behavior Patterns

Nocturnal and elusive; they emerge at night to feed. They undergo incomplete metamorphosis (egg, nymphal stages, adult) and require a blood meal to advance to each life stage.

Risks & Benefits

Significant household pest. Risks include itchy skin welts/allergic reactions from bites, sleep deprivation, and psychological distress. They are not known to transmit diseases to humans but are difficult and expensive to eradicate.
