How can bedbugs in a sofa be removed at home? - briefly
Vacuum the sofa meticulously, then treat the fabric with a high‑heat device or a labeled indoor insecticide spray, and finally seal the couch in a bed‑bug‑proof encasement. Repeat the cleaning and treatment weekly for four‑to‑six weeks to eradicate any remaining insects.

How can bedbugs in a sofa be removed at home? - in detail
Begin by confirming the presence of insects. Use a bright flashlight and a thin card to lift fabric seams; look for live bugs, dark‑red spots, or shed skins. Isolate the couch from other furniture to prevent spread.

Mechanical removal

Vacuum every surface, including cushions, crevices, and the frame, using a hose attachment. Immediately empty the canister into a sealed bag and discard outdoors.
Scrape seams and folds with a stiff brush; collect debris in a disposable container.

Thermal treatment

Apply a steam cleaner set to at least 130 °C (266 °F). Move slowly across all fabric areas, allowing steam to penetrate seams for 20–30 seconds each.
Place the sofa in direct sunlight or a heated garage for 48 hours, maintaining ambient temperature above 45 °C (113 °F). Cover the piece with a black tarp to retain heat.

Chemical control

Choose a residual spray labeled for bedbug control on soft furnishings. Apply according to label directions, focusing on stitching, under cushions, and the sofa frame.
After treatment, allow the product to dry fully before using the furniture again.

Encasement

Fit a zippered, bedbug‑proof cover over the entire sofa. Seal all seams. Keep the cover on for at least three weeks; any surviving insects will die without access to a blood meal.

Follow‑up monitoring

Place sticky traps around the sofa legs and beneath it. Check weekly for activity.
Repeat vacuuming and steam treatment weekly for one month to capture any newly hatched insects.

Maintain a clutter‑free environment, wash nearby linens at 60 °C, and seal cracks in walls or floorboards to eliminate hiding places. Consistent application of the steps above eradicates the infestation without professional services.
