Ep 38: Itchy Business: How to Navigate Pinworm Panic

Written By Brian Lee

In this Oh Gross! episode, Kara, Jennie, and Molly unpack the facts and fears around one of the most common (and least talked-about) parasites in the U.S.—pinworms.

These microscopic pests, officially known as Enterobius vermicularis, infect millions each year, especially kids. They’re easy to catch, awkward to talk about, and totally treatable.

So let’s get real about what they are, how they spread, and what you can do about it.

🧪 Jennie’s Lab Notes:

Wait, What Are Pinworms?

Pinworms are a type of roundworm that live in the human intestine and come out at night to lay their eggs—usually around the anus. This causes intense itching and, unsurprisingly, a lot of discomfort.

You can't catch them from your dog (pets don’t get human pinworms), but eggs can cling to pet fur, bedding, toys, or even float through the air.

How You Get Them

It’s not just from playing in the sandbox.

Pinworms spread through:

  • Touching contaminated surfaces (toys, sheets, toilet seats)

  • Nail-biting or poor handwashing

  • Petting a furry friend who’s been exposed

  • Inhaling airborne eggs during cleaning

Worms in your poop? Probably. In your dreams? Also possible—some kids with pinworms report nightmares and insomnia.

How to Know If You Have Them

Itching is the most common symptom, especially at night. But you might also:

  • See worms in your stool

  • Notice sleep disruptions or irritability

  • Be totally symptom-free (and still have them)

Doctors may use the “tape test,” flashlight check, or even nail scrapings to confirm a diagnosis. Keep a symptom diary to share with your healthcare professional.

Treatment & Prevention

Pinworms are treatable with medications like:

  • Pyrantel pamoate (OTC)

  • Mebendazole or Albendazole (prescription)

But meds alone aren’t enough. You’ll need a hygiene game plan:

  • Daily showers (not baths!)

  • Hot water laundry for bedding and clothes

  • Frequent handwashing and nail trimming

  • Disinfect surfaces and vacuum with a HEPA filter

Yes, treat the whole family—even if they aren’t itchy.
