Bed Bug

Human dwellings, specifically cracked and crevices near sleeping areas such as mattresses, bed frames, and upholstered furniture

Hematophagous (obligate blood feeders), primarily feeding on human blood during the night

Nocturnal and elusive; they undergo hemimetabolous metamorphosis with five nymphal stages, requiring a blood meal to molt between each stage.

Risks include itchy skin welts, allergic reactions, and significant psychological distress; they are not known to transmit diseases but are a major nuisance pest.
