Life cycle of a pinworm A grown pinworm is yellowish white, slender and about one centimetre long. Around 4 weeks after ingestion, the adult female moves down the gut and exits the body via the anus to lay a batch of eggs on the surrounding skin, often at night. The worm then dies, her reproductive mission complete.
Treating threadworms
For most people, treatment will involve taking a single dose of a medication called mebendazole to kill the worms. If necessary, another dose can be taken after 2 weeks.
However, hygiene measures alone may work. The worms die after about six weeks. Provided that you do not swallow any new eggs, no new worms will grow to replace them. So, if you continue the hygiene measures described above for six weeks, this should break the cycle of re-infection, and clear your gut of threadworms.

If it is a severe infection, symptoms may include: nervousness, restlessness, loss of appetite, weight loss, and girls may experience vaginal itching and irritation (vaginitis), if pinworms are near the vagina.
For most, it's a short stay, with the immune system evicting the worms in days or weeks and leaving no trace that the parasites were ever there. In a small percentage of people and other animals, though, the worms gain a permanent mouth-hold and can stick around the intestines for years.
