How should disinfection for lice be carried out? - briefly
Apply a licensed pediculicide (e.g., 1 % permethrin or pyrethrin) to dry hair, leave for the recommended duration, then rinse thoroughly; repeat the treatment in 7–10 days to target newly hatched nits. Wash clothing, bedding, and personal items in hot water and vacuum the living area to prevent re‑infestation.
How should disinfection for lice be carried out? - in detail
Effective lice eradication requires a systematic approach that addresses the infestation on the host, on personal items, and in the surrounding environment.
Begin with a thorough inspection. Separate the hair into sections and use a fine‑toothed lice comb, moving from scalp to tip. Examine each strand for live insects and viable nits. Remove any found organisms with the comb and discard them in sealed plastic.
Apply a proven pediculicide. Choose a product containing 1% permethrin, 0.5% malathion, or a dimethicone‑based formula, following the manufacturer’s dosage instructions precisely. Apply to dry hair, ensuring complete coverage from roots to tips. Leave the preparation on for the recommended duration, typically 10–15 minutes, then rinse thoroughly with lukewarm water. Repeat the treatment after seven days to eliminate newly hatched lice.
Sanitize personal belongings. Place clothing, bedding, and towels used within the previous 48 hours in a dryer on high heat for at least 30 minutes, or seal non‑washable items in a plastic bag for two weeks. Wash all washable fabrics in hot water (minimum 130 °F/54 °C) and dry on high heat.
Treat the environment. Vacuum carpets, upholstered furniture, and car seats, discarding the vacuum bag or cleaning the canister immediately. Soak hairbrushes, combs, and hair accessories in hot water (≥130 °F) for 10 minutes, then dry or replace them.
Monitor for recurrence. Conduct weekly inspections for four weeks, using a lice comb to detect any remaining nits. If live insects reappear, repeat the chemical treatment and reinforce environmental decontamination.
Document the process. Keep a record of dates, products used, and inspection findings to ensure compliance with the treatment schedule and to provide evidence for healthcare providers if needed.
