Bed bug (likely nymph)
Cimex lectularius
- Order & Family
- Hemiptera; Cimicidae
- Size
- Adults are about 4–7 mm long; nymphs range from roughly 1–6 mm. The pictured insect appears very small, possibly a juvenile.
Natural Habitat
Primarily indoors, hiding in mattress seams, bed frames, upholstered furniture, cracks, and clothing. They are associated with sleeping areas and human dwellings.
Diet & Feeding
Feeds exclusively on blood, chiefly from humans but sometimes other warm-blooded animals. It usually feeds at night and may become reddish after a meal.
Behavior Patterns
Nocturnal, wingless, and secretive; it hides during daylight and can survive months without feeding. Females lay eggs in protected crevices, and infestations spread through luggage, clothing, furniture, and nearby rooms.
Risks & Benefits
Bites cause itchy, inflamed welts and can trigger allergic reactions, though bed bugs are not established disease vectors. They provide no meaningful household or ecological benefit.
