Found worldwide in human dwellings, typically nesting in cracks, crevices, mattress seams, and bed frames near sleeping hosts.

Obligate hematophages, primarily feeding on human blood, though they may bite other warm-blooded animals if humans are unavailable.

Nocturnal parasites that emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and can survive for months without a blood meal.

Significant household pest causing itchy bites, allergic reactions, and psychological distress. They are not known to transmit diseases to humans but cause ecosystem disruption in indoor environments.
