How to remove clothing lice? - briefly
Wash the clothing in hot water (≥ 130 °F) and tumble‑dry on high heat for at least 30 minutes, or seal items in a plastic bag for two weeks to starve the parasites. Afterward, examine the fabric and repeat the process if any live insects are still visible.
How to remove clothing lice? - in detail
Lice that infest clothing require prompt, thorough eradication to prevent re‑infestation and spread to the body. The following protocol outlines each stage of the process, from detection to long‑term prevention.
Detection and isolation
- Examine all garments, linens, and accessories that have been in close contact with the infested person. Look for live insects, nits attached to fibers, or small dark spots indicating droppings.
- Separate suspect items from clean laundry. Place them in sealed plastic bags to contain any mobile insects while treatment is prepared.
Thermal treatment
- Machine‑wash contaminated fabrics in hot water, temperature ≥ 60 °C (140 °F), for at least 30 minutes. Use a high‑efficiency detergent.
- Immediately transfer washed items to a dryer set on the highest heat setting for a minimum of 20 minutes. Heat above 55 °C (130 °F) kills all life stages of the parasite.
- For items that cannot be machine‑washed (e.g., delicate fabrics, shoes), apply a portable steam cleaner delivering steam at ≥ 100 °C (212 °F) for several seconds on each surface.
Freezing method
- If heat treatment is unsuitable, place items in a freezer capable of maintaining –20 °C (–4 °F) for at least 72 hours. Freezing at this temperature eliminates eggs, nymphs, and adults.
Chemical approach
- For stubborn infestations, use a lice‑specific insecticide approved for fabrics. Follow manufacturer instructions regarding concentration, exposure time, and rinsing.
- After chemical application, re‑wash the items as described above to remove residue.
Disposal of non‑treatable items
- Seal heavily infested clothing, bedding, or accessories in impermeable bags. Dispose of them according to local waste‑management regulations or incinerate if permitted.
Environmental sanitation
- Vacuum carpets, upholstery, and vehicle interiors thoroughly. Empty the vacuum canister into a sealed bag and discard it.
- Clean and disinfect any hard surfaces that may have contacted the infested garments using a solution of 0.1 % bleach or an equivalent disinfectant.
Preventive measures
- Store clean clothing in airtight containers.
- Rotate laundry cycles so that items are not repeatedly worn without washing.
- Perform regular inspections of personal clothing, especially after travel or contact with potentially infested environments.
By adhering to this comprehensive regimen, all life stages of the parasite are eliminated from garments, reducing the risk of recurrence and ensuring a safe, lice‑free wardrobe.
