Bed Bug (nymph stage)

Natural Habitat

Commonly found in residential and hospitality settings, specifically in mattress seams, bed frames, furniture, and wall crevices near human sleeping areas.

Diet & Feeding

Obligate hematophages, meaning they feed exclusively on the blood of vertebrates, primarily humans.

Behavior Patterns

They are nocturnal, emerging at night to feed. They undergo incomplete metamorphosis with five nymphal stages, each requiring a blood meal to molt. They can survive months without feeding.

Risks & Benefits

Risks include itchy allergic reactions to bites, sleep deprivation, and psychological distress. While not known to transmit diseases to humans, they are a significant nuisance and expensive to eradicate. They provide no known ecosystem benefits in human habitats.
