Bed Bug

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

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

Nocturnal parasites that hide during the day and emerge at night to feed; they undergo incomplete metamorphosis with five nymphal stages, each requiring a blood meal to molt

Risks include itchy skin welts, allergic reactions, secondary infections from scratching, and psychological distress; they are not known to transmit diseases to humans. There are no known benefits to the ecosystem from their presence in human environments.
