How can I get rid of bedbugs on a sofa? - briefly
Remove all cushions, vacuum seams and crevices thoroughly, then steam‑clean the upholstery at 130 °C (266 °F) for at least 20 minutes. Seal the sofa in a plastic cover for two weeks and apply a labeled insecticide spray to any remaining cracks, repeating treatment after the incubation period.
How can I get rid of bedbugs on a sofa? - in detail
Bedbugs hide in seams, cushions, and fabric folds of a couch. Begin by confirming their presence: look for live insects, dark spots (feces), or tiny white eggs on the upholstery and inside the frame.
Remove all detachable covers and wash them at 60 °C (140 °F) for at least 30 minutes. Dry on high heat to kill any remaining stages.
Vacuum the entire surface, paying special attention to seams, tufts, and under cushions. Use a brush attachment to dislodge insects from fabric. Empty the vacuum bag or canister into a sealed plastic bag and discard it outside the home.
Apply heat treatment if the sofa can tolerate it. Portable heaters or a professional steam machine can raise the temperature of the upholstery to 50–55 °C (122–131 °F) for 30–45 minutes, a range lethal to all life stages. Ensure even coverage; move the nozzle slowly across every area.
If heat is unsuitable, use a residual insecticide labeled for indoor fabric pests. Apply according to label directions, focusing on cracks, stitching, and the underside of the frame. Allow the product to dry completely before using the sofa again.
Consider a professional exterminator for severe infestations. They can combine heat, fumigation, and specialized chemicals, and they have equipment to treat internal couch structures that are inaccessible to homeowners.
After treatment, prevent re‑infestation by:
- Enclosing the sofa in a protective cover that does not trap moisture.
- Inspecting second‑hand furniture before purchase.
- Reducing clutter around the seating area.
- Regularly vacuuming and laundering removable fabrics.
Consistent monitoring for a few weeks will confirm the success of the eradication effort.
