How do you wash clothing infected with lice? - briefly

Launder infested garments in water at least 130 °F (54 °C) for a minimum of 10 minutes, then tumble‑dry on the highest heat setting for at least 20 minutes. Items that cannot be washed should be placed in a sealed bag for two weeks to eliminate any remaining lice.

How do you wash clothing infected with lice? - in detail

When garments are suspected of harboring lice, immediate treatment prevents re‑infestation. Follow these precise actions:

  1. Separate all potentially contaminated items from regular laundry. Include clothing, bedding, towels, and hats.
  2. Set the washing machine to the hottest temperature the fabric can tolerate—typically 130 °F (54 °C) or higher. Heat kills both adult lice and their eggs.
  3. Add a regular detergent; a bleach‑free formula is sufficient because high heat is the primary lethal factor.
  4. Run a full wash cycle lasting at least 30 minutes. The extended duration ensures thorough saturation and heat penetration.
  5. Transfer the washed items directly to a dryer. Use the highest safe dryer setting—usually “high heat” for 20–30 minutes. The combination of heat and tumbling eliminates any surviving nits.
  6. For fabrics that cannot withstand high temperatures, place them in a sealed plastic bag for two weeks. Lice cannot survive longer than 48 hours without a host, and the sealed environment deprives them of oxygen.
  7. Inspect all items after drying. If any live lice are observed, repeat the wash‑dry process or consider professional cleaning.
  8. Clean the washing machine and dryer lint trap to remove any stray insects or eggs that may have escaped during the cycle.

Additional precautions: vacuum floors and upholstery, and store untreated items in sealed bags until the two‑week period expires. By adhering strictly to these steps, the risk of ongoing infestation is eliminated.
