Bed Bug

Indoor environments, primarily in cracks and crevices in hotels, houses, and apartment buildings, typically near sleeping areas.

Obligate hematophagous (blood-feeding) insects, primarily feeding on human blood during the night.

Nocturnal and elusive; they hide during the day and are attracted to heat and carbon dioxide emitted by hosts. They undergo incomplete metamorphosis (egg, nymph, adult).

Risks include itchy skin welts, allergic reactions, psychological distress, and secondary skin infections from scratching. They are not known to transmit diseases to humans but are significant domestic pests.
