How to wash a sofa to remove bed bugs? - briefly
Use a steam cleaner set to at least 120 °C to treat the entire sofa, focusing on seams, cushions and any removable covers, then vacuum thoroughly with a HEPA filter. Follow with a professional heat‑treatment or freeze the upholstery for 48 hours to ensure any remaining insects are eliminated.
How to wash a sofa to remove bed bugs? - in detail
Cleaning a sofa to eliminate bed‑bug infestations requires a systematic approach that combines physical removal, heat treatment, and targeted insecticide use.
Begin by isolating the piece from other furniture. Remove any removable covers, cushions, and throws. Wash fabric items in hot water (minimum 120 °F/49 °C) for at least 30 minutes, then dry on high heat for 30 minutes to ensure all life stages are killed. If the material cannot be laundered, place it in a sealed plastic bag and expose it to a professional-grade dryer for the same duration.
Next, vacuum the entire sofa thoroughly. Use a hose attachment to reach seams, crevices, and underside of cushions. Empty the vacuum canister into a sealed bag and dispose of it outside the home. This step removes adult insects, eggs, and shed skins.
Apply a steam cleaner set to a temperature of at least 212 °F (100 °C). Move the steam nozzle slowly across all surfaces, paying particular attention to stitching, folds, and hidden pockets. Steam penetrates deep enough to kill hidden bugs without damaging most upholstery fabrics.
For non‑removable sections, spray a residual insecticide specifically labeled for bed‑bug control. Follow label directions regarding dilution, application rate, and safety precautions. Apply a thin, even coat to the frame, legs, and any hard‑surface parts. Allow the product to dry completely before re‑assembling cushions.
After treatment, let the sofa air dry in a well‑ventilated area for at least 24 hours. Use fans to accelerate airflow if needed. Once dry, replace laundered covers and cushions.
Maintain vigilance by regularly inspecting seams and using interceptor traps under furniture legs. Reduce clutter around the sofa to limit hiding places. Repeat vacuuming and steam treatment monthly for the first three months to prevent re‑infestation.
