How to fight clothing lice? - in detail
Clothing lice infestations require rapid identification and systematic eradication. Initial inspection should focus on seams, cuffs, and pockets where adult insects and nymphs hide. Use a bright light and a magnifying lens to locate live specimens or eggs. If infestation is confirmed, follow a multi‑step protocol.
- Isolation – Place all affected garments in sealed plastic bags to prevent spread. Keep untreated items separate.
- Thermal treatment – Wash items in water at a minimum of 60 °C (140 °F) for at least 30 minutes. Follow with a high‑heat dryer cycle of 70 °C (158 °F) for 20 minutes. Heat destroys both lice and their eggs.
- Chemical application – For fabrics that cannot endure high temperatures, apply an insecticidal spray approved for textile use. Ensure even coverage, especially in folds and seams. Allow the product to act for the manufacturer‑specified duration before laundering.
- Vacuuming – Vacuum storage areas, closets, and surrounding surfaces with a HEPA‑filter vacuum. Dispose of the vacuum bag or empty the canister into a sealed container immediately.
- Re‑inspection – After treatment, examine garments again under magnification. Repeat thermal or chemical steps if any life stages remain.
Preventive measures reduce recurrence:
- Store clean clothing in airtight containers.
- Rotate seasonal wardrobes, inspecting each item before storage.
- Maintain indoor humidity below 50 % to discourage lice development.
- Use insect‑repellent sachets (e.g., cedar or lavender) in closets, replacing them regularly.
When dealing with delicate fabrics such as silk or wool, opt for professional dry‑cleaning services that employ specialized pest‑control protocols. Documentation of the treatment process assists in tracking effectiveness and provides evidence for potential repeat infestations.
