How should a comb be treated if a child has lice? - briefly

After each use, immerse the comb in hot water (at least 130 °F/54 °C) or a lice‑killing solution for 10 minutes, then rinse and allow it to air‑dry completely. Store it separately from other grooming tools until the infestation is cleared.

How should a comb be treated if a child has lice? - in detail

When a child is infested with lice, the comb used to remove the insects must be decontaminated after each session to prevent re‑infestation and spread to other family members.

1. Immediate cleaning

   • Rinse the comb under hot running water to dislodge any attached nits or lice.
   • Scrub the teeth with a stiff brush (e.g., an old toothbrush) while water runs.

2. Disinfection

   • Soak the device for at least 10 minutes in a solution of one part 70 % isopropyl alcohol to one part water, or in a diluted bleach mixture (1 % sodium hypochlorite).
   • Alternatively, place the comb in a dishwasher on the top rack, using a hot wash cycle (≥ 60 °C/140 °F).

3. Rinsing and drying

   • Rinse thoroughly with clean water to remove any chemical residue.
   • Dry completely on a clean towel or paper towel; moisture can promote bacterial growth.

4. Storage

   • Store the cleaned comb in a sealed plastic bag or airtight container until the next treatment.
   • Label the container with the date of last use for tracking.

5. Replacement considerations

   • Inspect the comb for bent or damaged teeth after each cleaning cycle.
   • Replace the tool if any part is compromised, as ineffective teeth may miss nits and reduce treatment efficacy.

Following this protocol after every combing session eliminates live lice, kills viable eggs, and minimizes the risk of cross‑contamination within the household.
