Natural Habitat

Typically found in human dwellings, hidden in cracks, crevices, upholstery, and especially mattresses or bed frames near their host's sleeping area.

Diet & Feeding

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

Behavior Patterns

They are nocturnal, emerging at night to feed. They go through a simple metamorphosis consisting of egg, five nymphal stages, and adult. They travel by crawling or hitchhiking on luggage and clothing.

Risks & Benefits

Risks include itchy bites, allergic reactions, and significant psychological distress or insomnia; they are not known vectors of disease. There are no ecological benefits to humans.
