You do not need to sterilize the whole house. You need a consistent routine that removes eggs from the body, keeps them out from under fingernails and prevents them from returning to the mouth.
Every morning
- Shower soon after waking; avoid shared baths.
- Put on clean underwear and clothing.
- Place pajamas in the laundry without shaking them.
- Wash hands carefully with soap and warm water.
During the day
- Wash hands after using the toilet, after changing diapers and before eating or preparing food.
- Keep fingernails short and clean.
- Discourage nail-biting, thumb-sucking and scratching.
- Use separate towels and washcloths.
- Clean toilet seats and frequently touched bathroom surfaces regularly.
At bedtime
- Use clean, close-fitting underwear and clean pajamas.
- Wash hands before bed.
- Follow any medication or product directions exactly; do not improvise doses.
Laundry without spreading eggs
- Do not shake bedding, towels or clothing.
- Wash affected items frequently in hot water—CDC guidance specifies at least 130°F—when the fabric allows.
- Dry on high heat.
- Wash hands after handling dirty laundry.
How long?
Follow the routine throughout treatment and for two weeks after the last medicine dose. If symptoms return, do not simply repeat products indefinitely. Confirm the diagnosis and ask a healthcare professional whether household members, timing or another cause needs attention.
