How to disinfect a sofa from lice? - in detail
Eliminating lice from a couch requires a systematic approach that combines physical removal, chemical treatment, and preventive measures.
Begin with thorough inspection. Use a bright light and a fine-toothed comb to locate adult insects, nymphs, and eggs on upholstery, seams, and cushions. Collect specimens in a sealed container for identification, if necessary.
Next, detach removable covers and wash them at the highest temperature tolerated by the fabric (≥ 60 °C). For non‑removable sections, apply a vacuum cleaner equipped with a HEPA filter, moving slowly to capture all stages of the parasite. Immediately dispose of the vacuum bag or clean the canister to avoid re‑infestation.
After mechanical removal, treat the surface with an appropriate insecticide. Choose a product registered for lice control on indoor fabrics, following label instructions regarding concentration, contact time, and ventilation. Apply the solution evenly using a spray bottle, ensuring saturation without over‑wetting. Allow the treated area to dry completely before reuse.
If chemical agents are undesirable, consider natural alternatives:
- Diluted tea‑tree oil (1 % solution) sprayed lightly, repeated after 24 hours.
- A mixture of 0.5 % hydrogen peroxide applied with a cloth, followed by thorough rinsing.
Both options require confirmation of fabric compatibility to prevent discoloration.
Finally, implement preventive steps to reduce recurrence:
- Maintain low indoor humidity (≤ 50 %).
- Use protective couch covers that can be laundered regularly.
- Perform monthly vacuuming of upholstery.
- Inspect pets and bedding for lice, treating any secondary hosts promptly.
Adhering to this protocol eliminates the infestation and minimizes the risk of future outbreaks.
