Bed Bug (Nymph)
Cimex lectularius
- Order & Family
- Order: Hemiptera, Family: Cimicidae
- Size
- 1.5 mm to 4.5 mm (nymphs vary by instar stage; adults reach 5-7 mm)
Natural Habitat
Typically found in human dwellings, hidden in cracks, crevices, bed frames, mattresses, and behind wallpaper in close proximity to sleeping areas.
Diet & Feeding
Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans.
Behavior Patterns
Nocturnal and elusive. They undergo five nymphal stages (instars) before reaching maturity, requiring a blood meal to molt into each subsequent stage. They are attracted to heat and carbon dioxide emitted by hosts.
Risks & Benefits
Risks include itchy skin rashes, psychological distress (insomnia/anxiety), and potential allergic reactions. While they are not known vectors of disease transmission to humans, infestations are difficult and costly to eradicate. They offer no known ecosystem benefits in human environments.
