Treating a pinworm infection is the easy part — a single dose of PinAway handles that. The harder challenge is breaking the reinfection cycle. Pinworm eggs can survive on surfaces, under fingernails, and in bedding for weeks. These 10 hygiene steps will help ensure the infection doesn’t come right back.
1. Treat Every Household Member
This is the single most important step. Pinworm spreads silently — up to half of infected people have no symptoms. If one person in your household has pinworms, everyone should be treated at the same time, even if they feel fine.
2. Wash Hands Frequently and Thoroughly
Wash hands for at least 20 seconds:
- After using the bathroom
- Before eating or preparing food
- After diaper changes
- After touching your face or mouth
This is especially critical for young children, who often touch their mouths unconsciously.
3. Keep Fingernails Short and Clean
Pinworm eggs accumulate under fingernails when an infected person scratches. Keep nails trimmed short and scrub under them with a nail brush when washing hands.
4. Launder Bedding Immediately After Treatment
Wash sheets, pillowcases, pajamas, and underwear in hot water (at least 130°F / 54°C) the morning after starting treatment. Don’t shake bedding before washing — this disperses eggs into the air.
5. Shower Daily in the Morning
Morning showers remove eggs deposited overnight. Encourage all household members to shower (not just bathe) in the morning, especially in the days following treatment.
6. Wear Tight-Fitting Underwear
Wearing snug underwear to bed helps contain eggs and reduces contamination of bedding. Change underwear every morning.
7. Vacuum Carpets and Upholstered Furniture
Pinworm eggs can settle in carpet fibers and on upholstered surfaces. Vacuum thoroughly after starting treatment, and dispose of the vacuum bag promptly.
8. Clean Bathroom Surfaces
Wipe down toilet seats, toilet handles, faucet handles, and doorknobs with a disinfectant cleaner. These high-touch surfaces are common transmission points.
9. Discourage Nail Biting and Thumb Sucking
These habits create a direct route for pinworm eggs to enter the mouth. Work with children to break these habits — it’s also good practice for preventing many other infections.
10. Educate Without Shame
Pinworm infections are a normal childhood occurrence and have nothing to do with cleanliness or socioeconomic status. Talk openly with your children about hand washing and not scratching. Shame and secrecy make the infection harder to address and treat.
When to See a Doctor
While pinworm infections are easily treated at home, consult a healthcare provider if:
- Symptoms persist after completing both doses of treatment
- The infected person is under 2 years old
- Someone who is pregnant has the infection
- There are signs of a secondary skin infection from scratching
PinAway is here to make treatment straightforward and discreet. Follow these hygiene steps alongside treatment and you’ll break the cycle for good.
