Bed Bug (Nymph and Fecal Staining)

Found in human dwellings, typically in cracks and crevices, mattresses, bed frames, and behind baseboards.

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

Nocturnal parasites that 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 include itchy welts, allergic reactions, and psychological distress. They are not known to transmit diseases to humans but are significant household pests.
