How to get rid of lice on a comb? - briefly
Soak the comb in water hotter than 130 °F (or 55 °C) for at least 10 minutes, then scrub thoroughly with a nail brush and rinse under running hot water. Dry the comb with a clean towel or let it air‑dry completely before reuse.
How to get rid of lice on a comb? - in detail
Eliminating head‑lice eggs and nymphs from a hair‑comb requires a systematic approach that combines mechanical removal, chemical treatment, and thorough sanitation of the tool.
Begin by soaking the comb in hot water (minimum 130 °F/54 °C) for at least five minutes. The heat kills any live insects and loosens adhesive secretions that hold eggs to the teeth. After soaking, use a fine‑toothed metal comb to scrape each tooth, dislodging remaining debris. Perform this action over a white surface so that any residual particles are visible.
If heat alone is insufficient, apply an approved lice‑killing solution, such as a 1 % permethrin or 0.5 % malathion preparation, to the comb. Immerse the tool for the duration specified by the product label—typically 10–15 minutes—then rinse thoroughly under running water. Ensure that the solution reaches every crevice; a small brush can help spread the liquid.
Sanitize the comb after treatment. Place it in a sealed container with a disinfectant tablet (e.g., chlorine bleach diluted to 1 % concentration) for 10 minutes, then rinse and dry completely. Alternatively, run the comb through a dishwasher’s high‑heat cycle or place it in a microwave‑safe container and heat on high for one minute, provided the comb is metal and free of plastic components.
Repeat the entire process every 48 hours for a total of three cycles. This schedule aligns with the lice life cycle, ensuring that newly hatched nymphs are captured before they mature.
Key points to remember:
- Use water at least 130 °F (54 °C).
- Apply a lice‑specific insecticide according to label instructions.
- Disinfect with bleach, dishwasher, or microwave heat.
- Perform the routine three times, spaced two days apart.
Consistent execution of these steps removes all stages of the parasite from the comb and prevents re‑infestation.
