Bed bug

Found indoors, primarily hiding in cracks of mattresses, box springs, headboards, and furniture frames.

Obligate hematophage that feeds exclusively on the blood of humans and other warm-blooded animals.

Nocturnal parasites that emerge primarily at night to pierce skin and feed, retreating into dark harborages during daylight.

Bites cause itchy, red welts and secondary skin infections from scratching; they are not known to transmit human pathogens.
