Bed Bug
Cimex lectularius
- Order & Family
- Hemiptera (Order), Cimicidae (Family)
- Size
- Adults typically range from 4 to 5 mm (0.16 to 0.20 inches) in length, about the size of an apple seed. Nymphs are smaller, ranging from 1.5 mm to 4.5 mm.
Natural Habitat
Bed bugs are found in close proximity to their hosts. This includes mattresses, bed frames, headboards, box springs, furniture, cracks in walls, under wallpaper, electrical outlets, and any small crevice where they can hide during the day and emerge to feed at night.
Diet & Feeding
Strictly hematophagous, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans, but also pets, birds, and other mammals.
Behavior Patterns
Bed bugs are primarily nocturnal, feeding on sleeping hosts. They are highly adept at hiding in cracks and crevices during the day. Females lay 1-5 eggs per day, which hatch in about 1-2 weeks. Nymphs molt five times, requiring a blood meal between each molt to reach maturity, a process that can take several weeks to months depending on conditions and food availability. They are resilient and can survive for months without feeding, especially in cooler temperatures.
Risks & Benefits
Risks: Bed bugs are considered a public health pest. While they are not known to transmit diseases, their bites can cause itchy welts, skin irritation, and allergic reactions in some individuals. Chronic infestations can lead to sleep deprivation, anxiety, and psychological distress. They can also be difficult and costly to eradicate. Benefits: There are no known direct benefits of bed bugs to humans or the ecosystem.
