Prevention

By Mayo Clinic staff

Methods to help prevent the spread of pinworm eggs include:

  • Wash in the morning. Because pinworms lay their eggs at night, washing the anal area in the morning can help reduce the number of pinworm eggs on your body. Showering may help avoid possible re-contamination in bath water.
  • Launder in hot water. Wash bed sheets, night clothes, underwear and towels in hot water to help kill pinworm eggs.
  • Don't scratch. Avoid scratching the anal area. Trim your child's fingernails so there's less space for eggs to collect. Discourage nail biting.
  • Wash your hands. To reduce your risk of getting or spreading an infection, be sure to wash your hands thoroughly after a bowel movement and before eating.
