How to get rid of a sofa infested with bedbugs? - briefly
Isolate the sofa in a sealed, heavy‑duty plastic bag and apply a high‑temperature treatment (above 120 °F/49 °C) for several hours, or have a licensed pest‑control professional apply a labeled bed‑bug insecticide. After treatment, vacuum thoroughly, wash removable covers on hot settings, and monitor for any remaining activity.
How to get rid of a sofa infested with bedbugs? - in detail
Eliminating bed‑bug colonies from a couch requires a systematic approach that combines mechanical removal, chemical treatment, and environmental control.
Begin by isolating the affected piece. Move the sofa away from walls, other furniture, and pets. Cover the surrounding floor with a disposable sheet to catch falling insects.

Mechanical extraction
- Vacuum the entire surface, paying special attention to seams, cushions, and any removable covers. Use a hose attachment with a narrow nozzle to reach deep crevices. Empty the vacuum bag or canister into a sealed plastic bag and discard it outdoors.
- Detach and wash all removable fabric components in hot water (≥ 60 °C / 140 °F) for at least 30 minutes, then tumble‑dry on high heat for 30 minutes. Heat kills all life stages.
- For non‑removable upholstery, steam‑clean at a temperature of 120 °C (248 °F) for several minutes. The steam must penetrate the fabric and reach the interior of the frame.
-
Chemical treatment
- Apply a labeled bed‑bug insecticide spray or aerosol directly onto the sofa’s frame, stitching, and underside. Follow the product’s safety instructions, ensuring adequate ventilation and personal protective equipment (gloves, mask).
- After the initial application, repeat the treatment after 7–10 days to target newly hatched nymphs that survived the first dose.
- Consider using a residual powder (e.g., diatomaceous earth) in cracks and crevices. The abrasive particles damage the insects’ exoskeletons, leading to dehydration.
-
Encasement
- Fit the sofa with a certified bed‑bug‑proof cover that seals all openings. The enclosure must be left on for at least 90 days, the typical lifespan of a bed‑bug egg, to ensure any survivors die inside.
-
Environmental control
- Raise indoor temperature to 50 °C (122 °F) for a minimum of 30 minutes using portable heaters, or lower it to below 0 °C (32 °F) for a similar period if freezing equipment is available.
- Reduce clutter around the couch to eliminate hiding places. Regularly inspect adjacent furniture and baseboards for signs of infestation.
-
Monitoring
If the infestation persists after two full cycles of the above protocol, professional pest‑control services equipped with specialized equipment (e.g., heat chambers, foggers) should be engaged. Prompt, thorough execution of each step maximizes the probability of complete eradication.
