Bed Bug (Nymph)

Found exclusively indoors, primarily hiding in beds, mattresses, box springs, bed frames, furniture, and cracks in walls near sleeping areas.

Hematophagous (feeds exclusively on the blood of warm-blooded animals, preferring humans).

Nocturnal and extremely elusive; they hide in tight crevices during the day and emerge at night to feed on sleeping hosts. Nymphs (like the one pictured) must take a blood meal to molt to the next stage.

Risks: Bed bugs cause itchy, irritating bites that can lead to allergic reactions, secondary skin infections, anxiety, and insomnia. They are major nuisance pests and very difficult/expensive to eradicate. Benefits: None known for humans or household ecosystems.
