How to treat an apartment for lice and nits? - briefly
Clean all linens and clothing by washing in water at least 130 °F (54 °C) and drying on high heat, then vacuum carpets, furniture, and cracks while discarding or sealing non‑washable items in a sealed bag for two weeks. Apply a lice‑specific insecticide spray to surfaces according to label directions and repeat after seven days.
How to treat an apartment for lice and nits? - in detail
Eliminate head‑lice infestations from a residence by following a systematic, evidence‑based protocol.
First, confirm the presence of live insects and viable eggs. Inspect hair, bedding, clothing, upholstered furniture, and personal items. Use a fine‑tooth comb on damp hair to collect specimens in a white container for visual verification.
Next, isolate contaminated textiles. Place all washable fabrics—sheets, pillowcases, blankets, towels, clothing—in sealed plastic bags for transport to the laundry area. Wash at a minimum temperature of 60 °C (140 °F) for 30 minutes, then tumble‑dry on high heat for at least 20 minutes. For items that cannot be laundered, seal in airtight bags for two weeks to deprive lice and nits of a viable environment.
Vacuum every carpet, rug, and floor surface thoroughly. Pay special attention to seams, edges, and under‑furniture spaces where eggs may adhere. Empty the vacuum canister or replace the bag immediately after use, sealing the waste in a plastic bag before disposal.
Treat non‑launderable surfaces with a suitable insecticide labeled for head‑lice control. Apply a spray containing 0.5 % permethrin, 1 % pyrethrin, or a dimethicone‑based product, following manufacturer instructions for contact time and ventilation. Avoid excessive saturation; a light mist covering visible areas suffices. After treatment, allow the room to air out for at least one hour before re‑occupancy.
Disinfect personal grooming tools. Soak combs, brushes, and hair accessories in hot water (≥ 55 °C / 131 °F) for 10 minutes, then dry on a clean towel. For plastic items, submerge in a solution of 3 % hydrogen peroxide for 10 minutes if heat is unavailable.
Finally, implement preventive measures. Encourage regular hair‑checking routines, especially after close contact with others. Store hats, scarves, and headwear in sealed containers when not in use. Maintain a cleaning schedule that includes weekly vacuuming and periodic laundering of bedding at high temperature.
By executing these steps in a coordinated manner, the dwelling will be cleared of live lice, viable eggs, and residual contamination, minimizing the risk of reinfestation.
