Bed Bug

Human dwellings, specifically in mattresses, bed frames, and furniture cracks

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans

Nocturnal activity, hiding during the day in tight crevices and emerging at night to feed while hosts are asleep

Causes itchy welts and psychological distress; they do not transmit diseases but can cause secondary skin infections from scratching
