Bed Bug

Indoor environments, primarily cracks and crevices near human sleeping areas (mattress seams, bed frames, headboards, and baseboards).

Obligate hematophagous (blood-eaters), 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 physical reactions like itchy welts, insomnia, and anxiety; while they are not known to transmit diseases, heavy infestations cause significant stress. There are no known benefits to the ecosystem.
