If your child has a pinworm infection, you can see worms in the anal region, especially if you look about 2 or 3 hours after your child has fallen asleep.
How long do you have worms before they come out?
After a few weeks, the female pinworms move to the end of the large intestine, and they come out of the body at night to lay their eggs around the anus (where poop comes out). The amount of time that passes from when someone swallows the eggs until the worms lay new eggs is about 1 to 2 months.
How long until pinworms are visible?
How soon do symptoms appear? Symptoms usually are noticed one to two months after infection. How are pinworms spread? Humans are the only known source of pinworms; pets and other animals do not have pinworms.
How long does it take worms to develop?
Once the larvae get to the intestine, they mature into adult worms and begin laying eggs — starting the cycle again. It takes about four weeks from the time a dog or cat eats the eggs for an adult worm to mature in the animal's intestine and start laying eggs.
When can you see threadworms?
You may be able to see threadworm if you examine your child at night. Take a torch, separate your child's buttocks and look carefully around the anus (and the opening to the vagina in girls). You might see tiny white threads that may be moving.
