Common Bed Bug (Nymph)

Domestic environments, specifically mattresses, bed frames, furniture, and cracks/crevices near human sleeping areas.

Obligate hematophage; feeds exclusively on human blood and occasionally other warm-blooded animals.

Nocturnal parasites that hide during the day and emerge at night to feed. They undergo five nymphal stages (instars) before reaching maturity, requiring a blood meal to molt at each stage.

Significant public health pests causing itchy welts, psychological distress, and potential allergic reactions. They are not known to transmit diseases to humans but infestations are difficult and costly to eradicate.
