How to treat a carpet for lice and nits? - briefly

Vacuum the carpet thoroughly, then treat the fibers with a lice‑specific spray or a diluted permethrin solution, allowing it to dry before a second vacuuming. Repeat the process after 7–10 days to eradicate any newly hatched nymphs.

How to treat a carpet for lice and nits? - in detail

Treating a carpet infested with head‑lice eggs requires a systematic approach that eliminates both live insects and dormant nits. Begin with a thorough visual inspection. Use a bright flashlight and a fine‑toothed comb to separate fibers and locate clusters of eggs. Mark heavily affected zones with tape to focus subsequent actions.

1. Vacuum

   • Run a high‑efficiency vacuum over the entire surface, paying special attention to marked areas.
   • Empty the canister or bag into a sealed plastic bag and dispose of it outside the home.
   • Repeat the vacuuming after 24 hours to capture any newly hatched lice.

2. Heat treatment

   • Apply a steam cleaner set to at least 212 °F (100 °C).
   • Move the nozzle slowly, allowing steam to penetrate deep into the pile.
   • Keep the carpet wet for 10–15 minutes, then allow it to dry completely to prevent mold growth.

3. Washing removable rugs

   • If the carpet or rug is machine‑washable, launder it on the hottest cycle permitted by the manufacturer.
   • Use a detergent containing an insecticide approved for textiles, following label instructions for concentration and contact time.
   • Dry on high heat for a minimum of 30 minutes.

4. Chemical application (if heat is insufficient)

   • Choose a product labeled for lice and nit control on fabrics, such as a pyrethrin‑based spray.
   • Test a small inconspicuous area for colorfastness.
   • Apply evenly, ensuring coverage of the carpet’s underside if accessible.
   • Allow the recommended dwell time, then ventilate the room thoroughly.

5. Post‑treatment sanitation

   • Wash all bedding, clothing, and items that have contacted the carpet in hot water.
   • Store vacuum bags, cleaning tools, and protective gloves in sealed containers for at least 48 hours before reuse.
   • Conduct a final inspection with a comb to confirm the absence of eggs.

Preventive measures include regular vacuuming, maintaining low indoor humidity, and using a carpet protector spray that repels insects. Consistent application of these steps eliminates infestations and reduces the risk of recurrence.
