Bed Bug

Indoor environments, primarily in cracks and crevices near sleeping areas (mattresses, bed frames, furniture, and baseboards).

Obligate hematophagous (feeds exclusively on blood), primarily from humans, but will feed on other warm-blooded animals if necessary.

Nocturnal and elusive; they hide during the day and emerge at night for blood meals. They undergo incomplete metamorphosis (egg, nymph, adult) and can survive for months without feeding.

Risks include itchy skin welts, allergic reactions, psychological distress, and secondary infections from scratching. They are not known to transmit diseases to humans. Benefits are none.
