Bed Bug

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

Obligate hematophages, primarily feeding on human blood, usually at night while the host is sleeping.

Nocturnal, elusive, and capable of surviving for several months without a blood meal; they undergo hemimetabolous metamorphosis from egg to adult.

Risks include itchy skin welts, allergic reactions, psychological distress, and secondary skin infections; they are significant household pests and do not provide ecological benefits to humans.
