Bed Bug

Found globally, primarily in human dwellings within cracks, crevices, mattresses, bed frames, and upholstered furniture.

Hematophagous; they feed exclusively on the blood of warm-blooded animals, primarily humans.

Nocturnal and elusive; they hide during the day and emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and can survive months without a meal.

Risks include itchy welts, allergic reactions, and psychological distress (insomnia/anxiety). They are not known to transmit diseases to humans. There are no known ecological benefits in domestic settings.
