The eggs then travel to the gut where they hatch and mature. 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. The eggs may cause intense itching, especially at night, so children can easily reinfect themselves by scratching the anus and scraping eggs under their fingernails.
These eggs can then be transferred to the mouth and the whole life cycle of the pinworm starts again. The eggs can survive on surfaces or objects such as furniture, kitchen surfaces and toothbrushes for up to 2 weeks in the right conditions and can infect other people if transferred to the mouth or food.
Your doctor might want to perform a test to make sure the problem is a pinworm infection. This is done by collecting the eggs from around the anus using sticky tape first thing in the morning.
Medication is available to kill the worms and this is usually prescribed for the person who is infected and all other members of the household.
One dose may be followed up with a second dose 2 weeks later to take care of any surviving worms. Although the medication is safe for humans, you should consult your doctor or chemist before commencing treatment. This page has been produced in consultation with and approved by:.
