Bed bug

Commonly found in human dwellings, specifically in cracks and crevices, mattresses, bed frames, and upholstered furniture.

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

Nocturnal parasites that emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and can survive for months without a blood meal.

Risks include itchy skin bites, allergic reactions, and psychological distress. While not known to transmit diseases to humans, they are a significant domestic pest requiring professional extermination.
