How to treat a sofa after lice appear? - in detail
Lice on upholstered furniture require immediate, thorough action to eliminate the insects and prevent re‑infestation.
First, isolate the affected piece. Move the sofa away from other furniture and restrict access for pets and children until treatment is complete.
Next, conduct a detailed inspection. Use a fine‑toothed comb or a lice detection brush to lift fabric fibers and locate live insects, nits, and eggs. Examine seams, cushions, and any removable covers.
Cleaning procedures:
- Vacuum – Run a high‑efficiency vacuum over every surface, including crevices, cushions, and the underside of the frame. Empty the canister into a sealed bag and discard it outdoors.
- Steam – Apply a handheld steamer at 212 °F (100 °C) for at least 10 seconds per spot. Heat penetrates deep into upholstery, killing lice at all life stages.
- Wash removable textiles – Remove cushion covers, slipcovers, and any fabric accessories. Wash on the hottest cycle the fabric permits (minimum 130 °F/54 °C). Dry on high heat for at least 30 minutes.
- Chemical treatment – If steam is insufficient, spray a lice‑specific insecticide approved for indoor upholstery. Follow manufacturer instructions, covering the entire sofa evenly. Allow the recommended contact time, then ventilate the room thoroughly.
After treatment, repeat vacuuming and visual inspection after 24 hours, then again after 7 days to confirm eradication.
Preventive measures:
- Place a protective, washable cover over the sofa.
- Maintain regular vacuuming of upholstered furniture.
- Wash bedding and clothing that have been in contact with the sofa at high temperature.
- Inspect pets for lice and treat them promptly, as they can serve as carriers.
By following these steps systematically, the sofa can be restored to a lice‑free condition and remain protected against future infestations.
