Bed Bug

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

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

Nocturnal and elusive; they are attracted to body heat and carbon dioxide. They undergo simple metamorphosis (egg, nymph, adult) and can survive for months without feeding.

Risks include itchy red welts, allergic reactions, and psychological distress. They are not known to transmit diseases to humans but present a significant pest control challenge.
