Bed Bug (nymph stage)

Natural Habitat

Found in human dwellings, typically in cracks and crevices, bed frames, mattresses, and furniture near sleeping areas.

Diet & Feeding

Obligate hematophages, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans. This specimen appears to have recently fed, as indicated by the elongated, darker abdomen.

Behavior Patterns

Mainly nocturnal, emerging at night to feed. They undergo cinq nymphal stages (instars) and must have a blood meal to molt into the next stage.

Risks & Benefits

Risks include itchy skin rashes, psychological distress, and allergic reactions to bites. They are not known to transmit diseases to humans. There are no known benefits to the ecosystem relative to human habitation.
