Kristen Bell says she caught anal worms from her daughter. Don't let it happen to your family

Actress Kristen Bell openly discussed her hilarious but fairly gross experience with 'anal worms' during a recent appearance on "The Joel McHale Show," and they're as unpleasant as they sound, according to reports.

The highlights?

The mother of two said the preschool her 3-year-old daughter Delta attends reported a case of pinworms among students.

When her daughter began scratching her bottom, Bell knew there was a problem. "Sure enough, I wiped and saw a little white worm," she told McHale.

Bell subsequently contracted a case herself. Pinworms can live on surfaces like clothing, bedding or carpets, according to Mayo Clinic. The small, thin white roundworms can be contracted if you swallow or breathe in their eggs, according to the CDC.

And for the moms who've read this and won't be able to sleep ever again, here are some ways you can try to prevent them from affecting -- or reinfecting -- you and your family, according to familydoctor.org:

Make sure your child washes his or her hands before a meal and after using the restroom.

Keep your child’s fingernails trimmed.

Discourage your child from nail-biting and scratching their anal area.

Be sure your child changes into a clean pair of underwear each day.

Have your child bathe in the morning to reduce egg contamination.

Open bedroom blinds and curtains during the day. Eggs are sensitive to sunlight.

Change your child’s night clothes, underwear and bedding.
