How can you treat furniture for lice and nits? - briefly

Vacuum all surfaces, then use a steam cleaner set to at least 130 °F for a minimum of 10 minutes, and seal or bag non‑washable items for two weeks or apply a lice‑specific insecticide spray according to the product label.

How can you treat furniture for lice and nits? - in detail

Treating upholstered items, mattresses, and other household furnishings for lice and their eggs requires a systematic approach that eliminates live insects, destroys nits, and prevents re‑infestation.

Begin with thorough mechanical removal. Use a high‑efficiency vacuum equipped with a brush attachment to suction all surfaces, seams, and crevices. Immediately seal the vacuum bag or container in a plastic bag and discard it. For removable covers, wash them in hot water (minimum 130 °F/54 °C) and tumble dry on high heat for at least 20 minutes. Non‑washable fabrics should be placed in a sealed bag and exposed to a dryer on high heat for the same duration, or left in direct sunlight for several hours.

Apply steam cleaning to items that cannot be laundered. A steam generator delivering temperatures of 212 °F/100 °C for a minimum of 10 seconds per spot penetrates fibers and kills both adult lice and nits. Move the nozzle slowly to ensure adequate exposure, especially in folds and cushions.

When mechanical methods are insufficient, introduce EPA‑registered lice control products. Options include:

  • Aerosol sprays formulated for household use, applied to surfaces according to label directions and left to dry before re‑occupying the area.
  • Powdered insecticide treatments (e.g., permethrin‑based powders) lightly dusted onto upholstery, allowed to sit for the recommended time, then vacuumed or brushed off.
  • Encapsulating sprays that coat fibers, creating a barrier that suffocates remaining insects.

After chemical application, ventilate the room for at least 30 minutes, then clean any residue to avoid skin irritation.

Isolate heavily infested pieces if immediate treatment is not possible. Wrap furniture in heavy‑duty plastic sheeting, sealing all edges with tape, and store the package for two weeks. The prolonged confinement deprives lice of a host, leading to their death.

Prevent future problems by maintaining a regular cleaning schedule: vacuum weekly, wash bedding at high temperatures, and inspect new second‑hand items before bringing them into the home. Use protective covers on mattresses and pillows that can be laundered regularly. Promptly treat any detected infestation on a person to reduce the likelihood of transfer to surrounding furnishings.
