Bed bug

Indoor environments, primarily hiding in cracks of mattresses, furniture, and bed frames.

Obligate hematophage, feeding exclusively on the blood of humans and other warm-blooded animals.

Nocturnal and highly secretive, emerging primarily at night to pierce skin and feed painlessly via anesthetic saliva.

Bites cause itchy, red welts and psychological distress, but they are not known to transmit infectious diseases.
