Bed Bug

Indoor environments, specifically in cracks, crevices, mattresses, bed frames, and upholstered furniture.

Obligate hematophages (blood-feeders), primarily targeting humans but also feeding on other warm-blooded animals.

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph stages, adult).

Risks include itchy allergic reactions to bites, sleep deprivation, and psychological distress. While not known to transmit diseases to humans, they are a significant pest of public health importance.
