How to remove lice from a comb? - briefly
Soak the comb in hot, soapy water (≥50 °C) for several minutes, then scrub the teeth with a nail‑brush or an old toothbrush to dislodge any remaining nits, rinsing repeatedly until the water runs clear. Afterwards, dry the tool completely or sterilize it in a dishwasher or by heating it on high for a few minutes.
How to remove lice from a comb? - in detail
To cleanse a hair comb of lice and nits, follow a systematic approach that combines mechanical removal, chemical treatment, and thorough rinsing.
Begin by disassembling the comb if it has removable teeth. Submerge the entire tool in hot water (at least 140 °F/60 °C) for five minutes. The temperature kills live insects and loosens adhesive secretions.
While the comb remains immersed, apply a lice‑specific spray or a solution of 0.5 % permethrin directly to the teeth. Allow the product to act for the time specified on the label, usually ten minutes. This step ensures that any remaining nits are neutralized.
After the chemical exposure, use a fine‑toothed metal or plastic pick to scrape each tooth. Work from the base toward the tip, removing visible debris. For stubborn residues, dip a soft brush (e.g., an old toothbrush) in diluted dish soap and scrub the teeth in a circular motion.
Rinse the comb under running water while gently shaking it to dislodge loosened particles. Follow with a final rinse in a mixture of one part vinegar to two parts water; the acidity helps dissolve any remaining adhesive.
Dry the comb completely by laying it on a clean towel or using a low‑heat hair dryer. Store the cleaned comb in a sealed plastic bag for at least 24 hours before reuse to prevent re‑infestation.
Summary of steps
- Soak in hot water (≥140 °F) for 5 min.
- Apply lice‑killing spray or 0.5 % permethrin solution; wait as directed.
- Scrape teeth with a fine pick; brush with soapy water if needed.
- Rinse under running water; follow with vinegar‑water rinse.
- Dry thoroughly; store sealed for 24 hours.
Consistent application of this protocol eliminates live lice, destroys nits, and removes residue, ensuring the comb remains safe for future use.
