Bed Bug (Nymph)

Natural Habitat

Found in close proximity to human sleeping quarters, including mattresses, bed frames, furniture, and cracks or crevices in walls.

Diet & Feeding

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

Behavior Patterns

Primarily nocturnal, emerging from hiding at night to feed. They undergo five nymphal stages, requiring a blood meal to molt into the next stage and eventually reach adulthood.

Risks & Benefits

Risks include itchy skin rashes, psychological distress, and potential allergic reactions from bites. They are not known to transmit diseases to humans. There are no ecological benefits to their presence in human dwellings; they are considered household pests.
