Bed Bug

Indoor environments, primarily living in cracks and crevices of mattresses, bed frames, and furniture near sleeping areas.

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

Nocturnal and elusive. They feed while the host is asleep, typically every 5–10 days, and go through five nymphal stages requiring blood meals to mature.

Risks include itchy allergic reactions, skin rashes, psychological distress, and potential secondary infections from scratching. They are not known to transmit diseases to humans.
