Bed Bug

Found globally in human dwellings, typically hiding in cracks, crevices, mattresses, bed frames, and upholstered furniture.

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

Nocturnal and elusive; they emerge at night to feed and are attracted by carbon dioxide and body heat. They undergo incomplete metamorphosis (egg, nymph, adult).

Risks include itchy skin welts, allergic reactions, and psychological distress/insomnia. They are not known to transmit diseases to humans but cause significant economic burden through infestations.
