Bed Bug (Nymph)

Found globally in human dwellings, typically hiding in cracks, crevices, bed frames, mattresses, and upholstered furniture.

Obligate hematophagous (blood-feeders), primarily feeding on human blood, though they may also bite other warm-blooded animals.

Nocturnal and elusive; they emerge from hiding spots at night to feed. They undergo hemimetabolous development (eggs, five nymphal stages, and adult), requiring a blood meal to molt to the next stage.

They represent a significant urban pest risk. While not known to transmit diseases, their bites cause itchy welts, allergic reactions, insomnia, and psychological distress. They have no ecological benefits in a domestic human environment.
