Bed Bug

Human dwellings, specifically in cracks, crevices, mattresses, and bed frames near hosts

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

Nocturnal, elusive, and photophobic; they undergo incomplete metamorphosis through five nymphal stages that each require a blood meal to molt

No known disease transmission, but they cause significant psychological distress, sleep deprivation, and itchy, allergic skin reactions from bites
