How to treat items after a lice infestation? - briefly
Launder all washable clothing, bedding, and towels in water at least 130 °F and tumble‑dry on high heat. Place non‑washable items in sealed plastic bags for a minimum of two weeks to ensure any remaining lice die.
How to treat items after a lice infestation? - in detail
After a lice outbreak, every item that may have contacted an infested person requires specific treatment to eliminate nits and prevent re‑infestation.
Clothing, linens, and towels should be placed in a washing machine on the hottest setting the fabric tolerates, typically 60 °C (140 °F) or higher. A full wash cycle followed by a high‑heat dryer for at least 30 minutes guarantees that any surviving eggs are destroyed. Items that cannot endure heat, such as delicate fabrics, must be sealed in a plastic bag for two weeks; the absence of a viable environment kills the lice within that period.
For non‑washable objects—backpacks, hats, hair accessories, and upholstered furniture—use a fine‑toothed comb to remove visible nits. Afterwards, apply a spray containing 0.5 % permethrin or a similar insecticide, following the manufacturer’s safety instructions. Allow the product to remain on the surface for the recommended contact time before wiping or vacuuming.
Hard surfaces such as countertops, doorknobs, and bathroom fixtures do not harbor lice, but thorough cleaning with a disinfectant solution removes any stray eggs. Vacuum carpets and upholstery, then discard the vacuum bag or empty the canister into a sealed plastic bag before disposal.
Items stored for future use, like seasonal clothing, should be kept in airtight containers. Adding a sachet of silica gel helps maintain a dry environment, which is unfavorable for lice survival.
A concise checklist:
- Wash washable fabrics at ≥ 60 °C; dry on high heat for ≥ 30 minutes.
- Seal non‑washable textiles in a zip‑lock bag for 14 days.
- Comb and treat accessories with approved insecticide spray.
- Clean hard surfaces with disinfectant; vacuum soft furnishings.
- Store unused items in airtight containers with desiccant.
Implementing these measures eliminates residual lice and reduces the risk of recurrence.
