How to treat lice in the house? - in detail
Treating a lice infestation within a residence requires a systematic approach that combines personal treatment, environmental sanitation, and ongoing monitoring.
Effective personal treatment begins with a thorough application of an approved pediculicide or a physically acting product such as dimethicone. Follow the manufacturer’s instructions regarding dosage, exposure time, and repeat application, typically after seven days to target newly hatched nymphs. After treatment, comb the hair with a fine-tooth nit comb at least twice a day for ten days, removing live lice and nits. Dispose of combed material by sealing it in a plastic bag and discarding it in an outdoor trash bin.
Environmental sanitation focuses on items that retain lice or nits. Wash all clothing, bedding, and towels used within the previous 48 hours in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes. For items that cannot be laundered, seal them in airtight plastic bags for two weeks, a period sufficient for lice to die without a host. Vacuum carpets, upholstered furniture, and vehicle seats thoroughly; discard vacuum bags or clean the canister immediately after use.
Non‑fabric surfaces require specific actions. Soak combs, brushes, and hair accessories in hot water (≥ 50 °C) for ten minutes, then dry. Clean hair‑care tools with alcohol wipes. Apply a low‑pesticide spray or steam treatment to carpets and upholstery if infestation persists after initial cleaning.
Monitoring continues for at least three weeks after the final personal treatment. Conduct daily inspections of the scalp and hair, focusing on the nape and behind the ears. Record any detection of live lice; if found, repeat the pediculicide cycle promptly. Maintain the cleaning regimen for the duration of monitoring to prevent re‑infestation.
Education of all household members reinforces prevention. Advise against sharing personal items such as combs, hats, or pillows. Encourage regular hair checks, especially after gatherings where close contact occurs.
By integrating precise personal treatment, rigorous environmental decontamination, and diligent follow‑up, a household can eradicate lice and minimize the risk of recurrence.
