How can lice be removed from a sofa? - briefly
To eradicate lice from a sofa, thoroughly vacuum all surfaces, including cushions and seams, then launder any removable covers in water at least 130 °F and tumble‑dry on high heat. Afterwards, treat the upholstery with a steam cleaner or a lice‑specific insecticide spray as directed, and repeat the process after 7–10 days to eliminate any newly hatched nits.
How can lice be removed from a sofa? - in detail
Removing lice from a sofa requires a systematic approach that combines mechanical extraction, chemical treatment, and environmental control. Begin by isolating the affected furniture from other seating to prevent spread. Vacuum the entire surface, including cushions, seams, and crevices, using a hose attachment that can reach tight spaces. Immediately discard the vacuum bag or clean the canister to avoid re‑infestation.
Next, apply a suitable pediculicide spray or powder designed for fabric use. Follow the product instructions precisely: apply an even coating, allow the recommended dwell time (usually 10–15 minutes), then brush the material with a stiff‑bristled upholstery brush to dislodge nits and adult insects. After brushing, vacuum again to collect dislodged debris.
For deep‑set infestations, consider steam cleaning. A handheld steamer set to at least 130 °C (266 °F) can kill lice and their eggs without damaging most upholstery fabrics. Pass the steam nozzle slowly over all areas, paying special attention to folds and stitching.
After treatment, wash any removable cushion covers or slipcovers in hot water (minimum 60 °C/140 °F) and tumble dry on high heat. For non‑removable fabric, place the sofa in direct sunlight for several hours; ultraviolet radiation and heat contribute to mortality of remaining parasites.
Finally, implement preventive measures: use protective couch covers that are washable, maintain regular vacuuming schedules, and avoid placing infested clothing or bedding on the furniture. Repeat the entire process after one week to eliminate any newly hatched lice that may have survived the initial treatment.
