What Do Pinworms Look Like?

Pinworms are white, can be seen with the naked eye, and are about the length of a staple. At night, adult pinworms can sometimes be seen directly on the person's pajamas or around the anal area. The best time to look for pinworms is at night when the person wakes up due to itching in the anal/rectal. This sensation is likely caused by migrating female worms depositing eggs and irritating the skin.
