«Remove all bedding, clothing, and personal items; wash them in hot water (≥130 °F) and dry on high heat, then vacuum carpets, upholstery, and any fabric surfaces thoroughly, discarding the vacuum bag or cleaning the canister afterward».
How should a room be treated for lice and nits? - in detail
Treating a living space for lice and their eggs requires a systematic approach that eliminates both adult insects and viable nits. The process begins with identification, proceeds through containment, thorough cleaning, and ends with preventive measures.
First, confirm the presence of live lice or viable eggs on bedding, clothing, upholstery, and floor surfaces. Visual inspection with a fine-toothed comb or magnifying glass can reveal moving insects and nits attached to hair shafts or fabric fibers. Once confirmed, isolate all potentially contaminated items.
Next, execute the cleaning phase:
- Launder all washable fabrics (sheets, pillowcases, blankets, clothing) in hot water at a minimum of 130 °F (54 °C) for at least 30 minutes, then dry on high heat for a minimum of 20 minutes. Heat kills both lice and nits.
- For non‑washable items (comforters, curtains, stuffed toys), place them in sealed plastic bags for two weeks. Lice cannot survive longer than 48 hours without a host; the extended confinement ensures mortality.
- Vacuum carpets, rugs, and upholstered furniture repeatedly, focusing on seams, crevices, and edges where eggs may adhere. Immediately dispose of vacuum contents in a sealed bag and discard.
- Apply a steam cleaner to hard surfaces, carpets, and upholstered pieces. Steam at temperatures above 130 °F penetrates fabric layers, destroying eggs that may be glued to fibers.
- Wipe all hard surfaces (tables, countertops, doorknobs) with a solution of 1 % hydrogen peroxide or a diluted bleach mixture (1 part bleach to 10 parts water). Contact time of at least five minutes is sufficient to eliminate any stray insects.
After cleaning, implement environmental controls to prevent re‑infestation:
- Maintain room temperature below 80 °F (27 °C) and humidity under 50 % when possible, as these conditions reduce lice viability.
- Store all clean clothing and bedding in sealed containers until the risk period (typically two weeks) has elapsed.
- Encourage regular use of a fine‑toothed comb on personal hair, with immediate laundering of any combed material.
Finally, monitor the environment for at least two weeks. Re‑inspect bedding and furnishings weekly; any new findings warrant an immediate repeat of the cleaning protocol. Consistent application of these steps eradicates the infestation and minimizes the likelihood of recurrence.
