Bed Bug (Nymph Stage)

Exclusively indoors close to human hosts; typically found in mattresses (seams and piping), box springs, bed frames, furniture cracks, wallpaper seams, and electrical outlets.

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

They are cryptic, nocturnal ectoparasites. They hide during the day in tight crevices and emerge at night attracted by CO2 and body heat to feed. They undergo 5 nymphal stages, requiring a blood meal to molt into the next stage.

Risks: Major nuisance pest; bites cause itching, welts, allergic reactions, and significant psychological distress/insomnia. They are difficult to eradicate. Benefits: None known for humans or common ecosystems.
