How to treat combs after lice? - briefly
Soak the comb in hot (≥130 °F/54 °C) water with detergent for at least 10 minutes, then rinse and place it in boiling water or run it through a dishwasher cycle. Allow it to air‑dry completely before reuse.
How to treat combs after lice? - in detail
After an infestation, the comb must be decontaminated to prevent re‑infestation and eliminate surviving eggs.
Begin by removing visible debris. Rinse the comb under hot running water (at least 130 °F/54 °C) while brushing the teeth of the comb with a stiff brush or an old toothbrush. This dislodges nits and adult insects stuck in the teeth.
Next, apply a disinfectant. Suitable options include:
- A solution of 1 % sodium hypochlorite (household bleach) diluted in ten parts water. Submerge the comb for 10 minutes, then rinse thoroughly.
- 70 % isopropyl alcohol. Soak the comb for 5 minutes, then rinse.
- White distilled vinegar (undiluted). Soak for 30 minutes, then rinse.
For plastic or metal combs, the bleach or alcohol method is safe. Wooden combs should avoid bleach; use vinegar or a mild detergent followed by a thorough rinse.
After chemical treatment, place the comb in a dishwasher (if dishwasher‑safe) on the top rack with a heated dry cycle, or alternatively, lay it on a clean towel and air‑dry in direct sunlight for at least 2 hours. Sunlight’s ultraviolet radiation adds an extra sterilizing effect.
If the comb cannot be submerged (e.g., delicate antique combs), wipe each tooth with a cotton swab saturated in alcohol, ensuring contact with every surface, then allow to dry completely.
Finally, store the cleaned comb in a sealed plastic bag or airtight container until the next use. This prevents accidental re‑contamination from the environment.
Regular inspection after each treatment session confirms that no lice or nits remain on the comb. Replace the comb if damage or persistent residues are observed.
