How to properly poison lice? - in detail
Effective lice eradication requires a systematic approach that combines appropriate insecticides, precise application techniques, and strict safety protocols.
Select an insecticidal agent approved for pediculicide use. Common options include:
- Permethrin 1 % lotion or spray, a synthetic pyrethroid that disrupts nerve function.
- Pyrethrins combined with piperonyl butoxide, enhancing potency against resistant strains.
- Malathion 0.5 % lotion, an organophosphate effective for severe infestations.
- Spinosad 0.9 % suspension, a biologically derived compound with low mammalian toxicity.
Prepare the treatment environment. Remove bedding, clothing, and personal items from the immediate area. Wash washable fabrics in hot water (≥ 60 °C) and tumble‑dry on high heat. Seal non‑washable objects in sealed plastic bags for two weeks to starve residual insects.
Apply the chosen product according to label instructions. Typical steps include:
- Distribute the insecticide evenly over the scalp and hair, ensuring coverage to the roots and behind the ears.
- Massage gently to facilitate absorption; avoid excessive force that could cause scalp irritation.
- Leave the preparation on the hair for the specified duration, usually 10 – 15 minutes for permethrin and 8 hours for malathion.
- Rinse thoroughly with lukewarm water; avoid hot water that may degrade the active ingredient.
After treatment, repeat the application after seven days to eliminate newly hatched nymphs that survived the initial dose.
Implement personal protective measures during handling:
- Wear disposable gloves and eye protection to prevent dermal and ocular exposure.
- Conduct application in a well‑ventilated area to reduce inhalation risk.
- Store remaining product in its original container, clearly labeled, out of reach of children and pets.
Monitor for adverse reactions such as itching, redness, or respiratory discomfort. If symptoms persist, discontinue use and seek medical advice.
Maintain long‑term control by educating all household members on avoidance of head‑to‑head contact, regular inspection of hair, and prompt treatment of any reappearance.
