How to get rid of lice on furniture? - briefly
Vacuum all upholstery and crevices, then apply a heat treatment such as steam or a lice‑specific insecticide spray. Repeat the procedure after 7–10 days to eliminate any newly hatched insects.
How to get rid of lice on furniture? - in detail
Eliminating head‑lice infestations from upholstered items requires a systematic approach that combines mechanical removal, heat treatment, and, when necessary, targeted chemicals.
Begin with thorough vacuuming. Use a high‑efficiency vacuum equipped with a narrow nozzle to extract nits and adult insects from seams, cushions, and crevices. Operate the machine slowly, overlapping each pass to ensure complete coverage. Immediately seal the vacuum bag or canister in a plastic bag and discard it to prevent re‑infestation.
Apply steam. A handheld steamer delivering temperatures of at least 130 °C (266 °F) kills lice and their eggs on contact. Move the steam nozzle across all fabric surfaces, paying special attention to folds, stitching, and hidden pockets. Allow the treated area to dry completely before reuse.
If the fabric can tolerate moisture, launder removable covers in hot water (≥60 °C or 140 °F) and tumble‑dry on high heat for a minimum of 30 minutes. For non‑washable items, consider a dilute solution of 0.5 % permethrin or a registered lice‑specific insecticide spray. Apply according to the product label, ensuring even distribution without oversaturation. After treatment, ventilate the area for several hours.
Isolate the affected furniture. Move it to a room that can be sealed or use plastic sheeting to cover it, reducing the chance of lice spreading to other surfaces. Maintain isolation for at least 48 hours, the typical lifespan of an adult louse, while monitoring for any remaining activity.
Implement preventive measures. Regularly vacuum upholstered pieces, keep fabrics dry, and avoid placing personal items such as hats or scarves on shared furniture. Encourage occupants to wash personal clothing and bedding in hot water after any suspected exposure.
By combining mechanical extraction, high‑temperature steam, appropriate chemical control, and strict isolation, lice can be eradicated from furniture with minimal risk of recurrence.
