Natural Habitat

Typically found in urban dwellings, specifically in cracks and crevices such as bed frames, mattresses, and furniture.

Diet & Feeding

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

Behavior Patterns

Nocturnal and elusive; they use heat and carbon dioxide sensors to find hosts, feed for 3–10 minutes, and then retreat to hide. They undergo incomplete metamorphosis (egg, nymph, adult).

Risks & Benefits

They do not knownly transmit diseases, but their bites can cause allergic reactions, itchy welts, insomnia, and significant psychological distress. They have no environmental benefits.
