How should I treat a sofa for bedbugs at home? - briefly
Isolate the sofa, encase it in a bed‑bug‑proof cover, and apply a labeled residual insecticide to seams, cushions, and crevices. After 24 hours vacuum thoroughly, repeat the spray in one week, and wash or steam‑clean any removable fabrics.
How should I treat a sofa for bedbugs at home? - in detail
Inspect the couch thoroughly. Use a bright flashlight and a magnifying lens to locate live insects, shed skins, and dark‑brown spots (fecal stains). Mark each infested area with tape for reference.
Separate the sofa from other furniture. Move it to a well‑ventilated room, close doors, and seal gaps with plastic sheeting to prevent bugs from escaping.
Apply heat. Portable steam cleaners set to at least 130 °F (54 °C) penetrate cushions, seams, and frames. Move the nozzle slowly, covering every surface for 10‑15 minutes. For larger pieces, rent a portable heating chamber that raises the internal temperature to 120‑130 °F for several hours; maintain that range for at least 4 hours to kill all life stages.
If heat is impractical, use a residual insecticide labeled for bedbugs. Choose a product that can be applied to fabric and upholstery. Follow label directions precisely: spray thin, even coats on cushions, undercovers, and crevices. Avoid over‑saturation, which can damage the material.
Vacuum the entire couch immediately after treatment. Use a HEPA‑rated filter, empty the canister into a sealed bag, and discard it outdoors. Pay special attention to folds, tufts, and stitching.
Encapsulate the sofa. Fit a zippered, airtight cover designed for bedbug control. Keep the enclosure on for at least 90 days, the period needed for any surviving eggs to hatch and be trapped.
Monitor continuously. Place passive sticky traps around the sofa’s legs and under the cover. Check them weekly for new activity. If any bugs appear, repeat steam or targeted insecticide applications.
Maintain a clean environment. Wash all removable covers, pillowcases, and nearby linens in hot water (≥120 °F) and dry on high heat for a minimum of 30 minutes. Reduce clutter to limit hiding places.
