Natural Habitat

Primarily indoors near human sleeping areas, including mattresses, bed frames, and furniture crevices.

Diet & Feeding

Strictly hematophagous, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans.

Behavior Patterns

Nocturnal insects that emerge from hiding at night to feed. They undergo a hemimetabolous life cycle through five nymphal stages, requiring a blood meal for each molt.

Risks & Benefits

Significant public health pests that cause itchy welts and psychological distress/anxiety. While not known to transmit diseases, heavy infestations can lead to secondary infections from scratching.
