Bed Bug

Dwellings, especially mattresses, bed frames, furniture, cracks in walls, and other dark, secluded areas where humans rest.

Strictly hematophagous, feeding exclusively on the blood of humans and other warm-blooded animals.

Nocturnal, typically feeding at night while hosts are sleeping. They are attracted to carbon dioxide and body heat. They hide in cracks and crevices during the day.

Potential risks include itchy red welts from bites, allergic reactions in some individuals, and secondary skin infections from scratching. They are not known to transmit diseases to humans. There are no known benefits.
