Common Bed Bug (Nymph)

Natural Habitat

Indoor environments, primarily residing in cracks, crevices, mattress seams, and upholstered furniture in residential and commercial buildings.

Diet & Feeding

Obligate hematophages; they feed exclusively on the blood of warm-blooded animals, primarily humans.

Behavior Patterns

Nocturnal and elusive; they use heat and carbon dioxide to locate hosts, feed for 5-10 minutes at night, and then retreat to hiding spots. They undergo incomplete metamorphosis (egg, nymphal stages, adult).

Risks & Benefits

Risks include itchy allergic skin reactions (welts), psychological distress, and secondary skin infections from scratching. They are not known to transmit diseases to humans. There are no ecological benefits in human environments; they are considered a major pest.
