Bed bug

Found in cracks, crevices, mattresses, and furniture within human dwellings.

Feeds exclusively on the blood of humans and other warm-blooded animals.

Nocturnal and highly secretive, emerging primarily at night to feed and retreating into tight shelters during the day.

Bites cause itchy, irritated skin welts and psychological distress, but they are not known to transmit human pathogens.
