But they need to be treated. Use a flashlight to check for pinworms. Look around the anus for the small, white worms. Look a few hours after your child goes to bed or check first thing in the morning. Check two nights or two mornings in a row.
Pinworms can be hard to see.
Your doctor may give you a special test for pinworms. After your child has a BM, you can put scotch tape over your child's anus. When you lift the tape up, you may see pinworms on the tape. If your child has been near another child with pinworms and has no itching, your child probably does not have pinworms. Pinworms are never around very long before they cause itching.
