Bed bug

Found exclusively in indoor environments, primarily hiding in mattress seams, bed frames, furniture cracks, and baseboards near human sleeping areas.

Obligate hematophages that feed exclusively on the blood of humans and other warm-blooded animals, typically piercing the skin every few days.

Nocturnal and highly secretive insects that aggregate in dark, protected harborages during the day and actively seek hosts using carbon dioxide and heat at night.

Their bites cause itchy, irritated skin welts and severe psychological distress, but they are not known to transmit infectious diseases to humans.
