Pin worms cause severe anal itching. This itching usually occurs mainly at night. A way to tell if u have it is, go into the bath room and in the dark use a flash light and the worms will be around and in the anus moving around. This must be treated like sort of like lice. Ask pharmacists for pin worm meds as in tx they sell behind counter. treat every 6 days and use 3 rounds. Wash all clothes, sheets, toilet, etc.. people in house hold. Otherwise you will never get rid of it. Mean while put a tad bit of vinager in your water and your animals to also help keep away. Trust me. I've Bern there and have 2 kids who have contacted it.

tboyd is right with his information. Pinworms are tiny white worms seen in and on the stool and they do cause itching. They are very common and there are OTC medications to get rid of them.
Pinworms can be treated with 'over-the counter' medication. Combantrin is available without a prescription. It can't hurt to try. good luck.
There are no home remedies to treat worms. You need to see your doctor to get stool testing and then treatment.
