Pinworms are a type of parasite that lives in the digestive system of humans. They are common throughout the world. Adult pinworms are about 0.5 in. (12.7 mm) long and look like little white threads. Pinworm eggs are so tiny, you'd need a microscope to see them.
Pinworm inhabits the colon and rectum, feeding on Escherichia coli (E. coli) bacteria in the stool. Late at night when children are asleep, the female pinworm, which measures about the length of a staple (0.5 inch or 13 millimeters), emerges from the anus and lays her eggs on the surrounding skin.
