How can kerosene be used to kill lice? - briefly

Apply a few drops of kerosene directly to the hair and scalp, cover with a towel for about 30 minutes, then wash the hair thoroughly with soap and water. The practice is hazardous due to the chemical’s flammability and toxicity and is therefore discouraged.

How can kerosene be used to kill lice? - in detail

Kerosene can act as a contact insecticide when applied directly to the scalp and hair. Its low‑viscosity hydrocarbon penetrates the exoskeleton of lice, disrupting respiratory pathways and causing rapid immobilization. The following protocol outlines a controlled application, safety measures, and post‑treatment procedures.

  1. Preparation

    • Obtain pure, unadulterated kerosene; avoid mixtures containing additives or dyes.
    • Wear disposable nitrile gloves and a protective apron to prevent skin absorption.
    • Ensure the treatment area is well‑ventilated; open windows and use a fan to disperse vapors.
  2. Application

    • Separate hair into small sections using a fine-toothed comb.
    • Saturate a clean cotton pad with a measured amount of kerosene (approximately 2 ml per section).
    • Dab the pad onto the scalp, focusing on the nape, behind the ears, and any visible infestations.
    • Allow the liquid to remain on the hair for 5–7 minutes; the insects will become visibly immobilized.
  3. Removal

    • Rinse hair thoroughly with warm water and a mild, oil‑free shampoo.
    • Perform a second combing pass with a lice‑comb to extract dead insects and nits.
    • Dispose of used cotton pads and gloves in a sealed, fire‑resistant container.
  4. Safety considerations

    • Kerosene is flammable; keep away from open flames, electrical switches, and hot surfaces.
    • Prolonged skin contact may cause irritation or dermatitis; limit exposure to the prescribed time.
    • Inhalation of vapors can produce respiratory irritation; maintain adequate airflow throughout the process.
  5. Effectiveness evaluation

    • Re‑inspect the scalp after 24 hours; repeat the procedure only if live lice are observed.
    • A second treatment 7–10 days after the initial application can address newly hatched nits that survived the first round.
  6. Legal and health advisories

    • Many health authorities classify kerosene as a non‑approved lice treatment; use may be restricted or discouraged in certain jurisdictions.
    • Consult a medical professional before employing this method, especially for children under 2 years, pregnant individuals, or persons with pre‑existing skin conditions.

The described method provides a direct chemical approach to eradicate head lice, but it carries significant fire and toxicity risks. Users must adhere strictly to safety protocols and consider alternative, medically approved treatments when available.
