How to get rid of lice in furniture? - briefly
Thoroughly vacuum all surfaces, then apply high‑temperature steam or wash removable covers in hot water, followed by a residual indoor‑safe insecticide spray. Repeat the treatment after one week to eliminate any newly hatched insects.
How to get rid of lice in furniture? - in detail
To eradicate head‑lice infestations from sofas, chairs, mattresses, and other upholstered pieces, follow a systematic approach that combines mechanical removal, thermal treatment, and, when necessary, chemical control.
Begin with a thorough inspection. Use a fine‑toothed lice comb or a bright lamp to locate live insects and nits on fabric seams, cushions, and hidden crevices. Mark affected zones to focus subsequent actions.
Mechanical elimination:
- Remove all removable covers, pillowcases, and slipcovers; launder them in hot water (≥ 60 °C) and dry on high heat for at least 30 minutes.
- Vacuum every surface with a HEPA‑rated attachment. Work slowly, overlapping strokes to detach eggs and larvae. Empty the vacuum bag or canister into a sealed plastic bag and discard it outside the home.
- Brush or shake non‑washable fabric outdoors to dislodge detached stages; collect debris in a sealed container.
Thermal methods:
- Apply a steam cleaner set to a temperature of 120 °C (250 °F) or higher. Steam each area for a minimum of 10 seconds, ensuring the fabric is saturated without causing damage.
- For small items, place them in a dryer on the highest heat setting for 30 minutes; this kills all life stages.
Cold treatment:
- Seal infested items in airtight polyethylene bags and freeze at –20 °C (–4 °F) for at least 48 hours. This is effective for cushions, pillows, and small accessories that cannot tolerate heat.
Chemical options (use only if mechanical and thermal steps fail):
- Apply a lice‑specific insecticide formulated for fabric use, following the manufacturer’s label precisely. Test a hidden area first to confirm colorfastness.
- After treatment, re‑vacuum the surface to remove residual dead insects and prevent re‑infestation.
Preventive measures:
- Keep fabric items dry; moisture encourages lice survival.
- Use protective slipcovers that can be laundered regularly.
- Limit contact between infested persons and upholstered furniture until treatment is complete.
- Conduct periodic vacuuming and visual checks, especially after travel or visits from known carriers.
By integrating inspection, thorough cleaning, heat or cold exposure, and targeted insecticide application when required, lice can be fully eliminated from household furnishings.
