How to get rid of lice in the house? - in detail
Effective eradication of head‑lice infestation in a residence requires a systematic approach that combines personal treatment, environmental cleaning, and preventive measures.
Personal treatment begins with a thorough application of a pediculicide shampoo or lotion that contains approved active ingredients such as permethrin or dimethicone. Follow the product instructions exactly, leaving the solution on the scalp for the specified duration before rinsing. After the initial treatment, repeat the application after seven to ten days to eliminate any newly hatched nymphs.
Mechanical removal complements chemical treatment. Use a fine‑toothed nit comb on wet, conditioned hair, section by section, from the scalp to the tips. Perform combing at least twice daily for one week, inspecting the comb after each pass and discarding any captured insects.
Environmental decontamination focuses on items that maintain contact with the head. Wash all bedding, pillowcases, and washable clothing in hot water (minimum 130 °F/54 °C) and dry on high heat for at least 30 minutes. For non‑washable fabrics, seal in a plastic bag for two weeks or place in a freezer at –4 °F (–20 °C) for 24 hours to kill lice and nits.
Vacuum all carpets, upholstered furniture, and floor mats thoroughly, paying special attention to seams and crevices where lice may hide. Dispose of the vacuum bag or clean the canister immediately after use. Items such as hairbrushes, combs, and hats should be soaked in hot water (130 °F/54 °C) for ten minutes, then dried on high heat.
Preventive strategies reduce the risk of re‑infestation. Encourage regular head inspections, especially after school or group activities. Advise against sharing personal items such as hats, hair accessories, and headphones. Maintain a clean household environment by laundering linens weekly and vacuuming high‑traffic areas regularly.
