How to treat clothing lice? - in detail

Clothing lice infestations require prompt, thorough action to eliminate the parasites and prevent re‑infestation. The following protocol combines chemical, mechanical, and environmental measures.

1. Immediate garment processing

   • Place all affected clothing, bedding, and accessories in sealed plastic bags for at least 48 hours; lice cannot survive without a host beyond 24–36 hours.
   • Wash items in hot water (minimum 130 °F / 54 °C) and tumble‑dry on high heat for at least 30 minutes.
   • For items that cannot be laundered, seal them in airtight containers for two weeks, then expose to direct sunlight for several hours.

2. Chemical treatment

   • Apply an approved pediculicide spray or powder labeled for clothing lice to fabrics that cannot be washed. Follow manufacturer instructions regarding concentration, contact time, and ventilation.
   • After treatment, allow the product to dry completely before handling the garments.

3. Mechanical removal

   • Vacuum carpets, upholstery, and vehicle seats thoroughly; discard the vacuum bag or empty the canister into a sealed bag and discard.
   • Use a fine‑toothed comb or lint roller on fabric surfaces to capture any remaining insects.

4. Environmental sanitation

   • Clean and disinfect storage areas, closets, and drawers with a diluted bleach solution (1 % sodium hypochlorite) or an EPA‑registered disinfectant.
   • Replace or wash curtains, pillowcases, and other textile accessories that have been in contact with the infestation.

5. Monitoring and follow‑up

   • Inspect treated garments and surroundings after 24 hours for any surviving lice or nits.
   • Repeat laundering and chemical application if live insects are detected.
   • Maintain a weekly inspection for at least three weeks to ensure complete eradication.

6. Preventive practices

   • Store clean clothing in sealed containers.
   • Avoid sharing personal items such as coats, scarves, or hats.
   • Conduct regular visual checks of clothing, especially after travel or contact with potentially infested environments.

By adhering to this comprehensive regimen, the infestation can be eradicated efficiently, minimizing the risk of recurrence.
