Bed Bug

Scientific Name: Cimex lectularius

Order & Family: Hemiptera / Cimicidae

Size: 4–5 mm (about the size of an apple seed)

Bed Bug

Natural Habitat

Found exclusively indoors, primarily near areas where people sleep. They hide in mattresses, bed frames, cracks, crevices, and electrical outlets.

Diet & Feeding

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans. They can survive several months without a meal.

Behavior Patterns

Nocturnal and elusive. They emerge at night to feed and are attracted by body heat and carbon dioxide. They crawl but do not fly or jump; they have a hemi-metabolous life cycle involving five nymphal stages.

Risks & Benefits

Risks include itchy allergic reactions, skin rashes, and psychological distress/insomnia. While they do not transmit pathogens like many other blood-feeders, infestations are difficult to eradicate and can cause significant economic cost. There are no known benefits to the ecosystem.
