Bed Bug (Nymph/Cast Skin)

Natural Habitat

Typically found in human dwellings, specifically in cracks and crevices, bed frames, mattresses, and upholstered furniture.

Diet & Feeding

Obligate hematophagous (blood-feeders), primarily targeting humans but also other warm-blooded animals.

Behavior Patterns

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo incomplete metamorphosis with five nymphal stages, each requiring a blood meal to molt.

Risks & Benefits

Risks include itchy bites, allergic reactions, and psychological distress. While they do not reliably transmit diseases to humans, they are a significant pest of public health importance and difficult to eradicate.
