How can a sofa be treated for lice? - briefly
Remove cushions and washable covers, launder them in water ≥ 130 °F and dry on high heat; then vacuum the sofa thoroughly, apply a lice‑approved fabric spray or steam‑cleaning treatment, and repeat the process after seven days to eliminate any newly hatched nits.
How can a sofa be treated for lice? - in detail
Treating a couch for lice requires a systematic approach that combines physical removal, thermal exposure, and, when necessary, chemical agents. The process begins with a thorough inspection. Use a bright light and a fine-toothed comb to locate adult lice, nymphs, and eggs (nits) on upholstery seams, cushions, and hidden crevices. Mark any infested areas with a removable sticker to track progress.
Physical removal
- Vacuum the entire sofa on the highest setting, paying special attention to seams, folds, and the underside of cushions. Empty the vacuum bag or canister into a sealed plastic bag and discard it outdoors.
- Detach removable cushion covers and wash them in hot water (at least 130 °F/54 °C) for 30 minutes, then tumble‑dry on high heat for a minimum of 20 minutes.
- For non‑removable fabric, place a damp cloth soaked in a mixture of water and mild detergent over suspected spots, then scrub gently with a soft brush to dislodge insects and eggs.
Thermal treatment
- Apply a portable steam cleaner set to a temperature of 212 °F (100 °C). Slowly move the steam head over the whole surface, ensuring the steam penetrates seams and stitching. Steam kills lice and nits within seconds.
- After steaming, allow the sofa to air‑dry completely. High humidity can promote re‑infestation.
Chemical treatment (if required)
- Choose a lice‑specific insecticide approved for upholstery, such as a pyrethrin‑based spray or a silicone‑based oil. Test the product on a hidden area to confirm colorfastness.
- Apply the spray evenly, following the manufacturer’s dosage instructions. Focus on seams, cushions, and any cracks where insects may hide.
- Let the product remain on the surface for the recommended contact time (usually 8–10 minutes), then ventilate the room by opening windows and using fans.
- After the waiting period, repeat vacuuming to remove dead insects and residual residues.
Post‑treatment measures
- Place protective slipcovers on the sofa and launder them weekly for at least three weeks.
- Reduce clutter around the seating area to limit hiding places.
- Conduct weekly visual checks for at least one month to confirm eradication.
By executing inspection, thorough cleaning, heat exposure, targeted chemical application, and ongoing monitoring, a couch can be effectively cleared of lice and remain lice‑free.
