Common bed bug (Nymph/Cast Skin)

Natural Habitat

Domestic environments, specifically cracks and crevices near sleeping areas such as mattresses, bed frames, and furniture.

Diet & Feeding

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

Behavior Patterns

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo incomplete metamorphosis, shedding their translucent exoskeletons (as seen in the image) as they grow through five nymphal stages.

Risks & Benefits

Significant public health pest. They cause itchy welts, psychological distress, and potential secondary skin infections from scratching. They are not known to transmit diseases but are difficult and costly to eradicate.
