Common Bed Bug (Nymph/Exuviae)

Human dwellings, specifically in cracks, crevices, bed frames, mattresses, and behind wallpaper or baseboards.

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

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo five nymphal stages, requiring a blood meal to molt into the next stage, leaving behind amber-colored cast skins (exuviae).

Risks include itchy welts, allergic reactions, psychological distress, and secondary skin infections from scratching. They are not known to transmit diseases to humans. There are no ecological benefits in a human domestic setting.
