Bed Bug
Cimex lectularius
- Order & Family
- Order: Hemiptera, Family: Cimicidae
- Size
- Adults are typically 4-5 mm (0.16-0.20 inches) long, similar in size to an apple seed. Nymphs are smaller and translucent.
Natural Habitat
Primarily found indoors in human dwellings, especially in bedrooms. They hide in mattresses, bed frames, box springs, headboards, cracks in walls, furniture, and even electrical outlets.
Diet & Feeding
Strictly hematophagous, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans.
Behavior Patterns
Bed bugs are nocturnal and hide during the day in cracks and crevices, coming out at night to feed. They are attracted to warmth and carbon dioxide. Females lay 1-5 eggs per day, totaling 200-500 eggs in their lifetime. Nymphs hatch in 6-17 days and mature in about 21 days.
Risks & Benefits
Risks: Bed bug bites can cause itchy welts, skin irritation, and in some individuals, allergic reactions. They do not transmit diseases, but their presence can lead to anxiety, stress, and sleep deprivation. Benefits: None known for humans; they are considered pests.
