See this bug in the Encyclopedia

Natural Habitat

Human dwellings, specifically in cracks and crevices near sleeping areas such as mattresses, box springs, and bed frames.

Diet & Feeding

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

Behavior Patterns

Nocturnal parasites that hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult).

Risks & Benefits

Risks include itchy skin welts, allergic reactions, and psychological distress. While they do not typically transmit diseases, crushed bed bugs leave blood stains on bedding. They offer no known ecological benefits to human environments.
