How can belongings be treated for lice and nits at home? - in detail
Treating personal items for head‑lice infestation requires eliminating both live insects and their eggs. Effective procedures involve heat, cold, chemical agents, and mechanical removal.
Washable fabrics such as clothing, bedding, and towels should be placed in hot water (minimum 130 °F / 54 °C) for at least five minutes, then dried on high heat for 20 minutes or longer. Heat destroys lice at all life stages; the temperature must be sustained throughout the load.
Non‑washable items—hats, scarves, stuffed toys, hair accessories—can be sealed in airtight plastic bags for two weeks. Lice cannot survive without a host for more than 48 hours; the extended period guarantees death.
If immediate use is necessary, apply a dryer on the highest setting for 30 minutes. The combination of high temperature and tumbling removes any remaining nits attached to fibers.
For items resistant to heat, freezing is an alternative. Place objects in a freezer set to –4 °F (–20 °C) for 24 hours. The low temperature kills both lice and eggs.
Vacuuming carpets, upholstery, and vehicle seats removes detached insects and egg shells. Use a vacuum with a HEPA filter, then discard the bag or clean the canister in hot, soapy water to prevent re‑infestation.
Chemical options include sprays containing 1% permethrin or pyrethrin, applied according to manufacturer instructions. Limit use to surfaces that can tolerate the formulation; avoid direct contact with skin or food‑preparation areas.
Summary of steps:
- Wash and dry washable textiles on hot settings.
- Seal non‑washable items in sealed bags for 14 days.
- Use a high‑heat dryer for items requiring rapid treatment.
- Freeze resistant objects at –20 °C for 24 hours if heat is unsuitable.
- Vacuum all soft surfaces, then clean the vacuum system.
- Apply approved insecticidal sprays only where safe and necessary.
Following these measures eliminates lice and nits from household belongings, reducing the risk of re‑infestation.
