Bedbugs in a sofa: what to do at home? - briefly

Isolate the sofa, vacuum seams and cushions, then seal it in a plastic bag for a few days. Apply a heat treatment above 45 °C or use a registered bed‑bug pesticide, and launder or discard any removable fabrics.

Bedbugs in a sofa: what to do at home? - in detail

Infestations of Cimex lectularius in upholstered furniture require immediate, systematic action to prevent spread and eliminate the insects.

First, isolate the affected piece. Move the sofa away from walls and other furniture, and cover adjacent items with sealed plastic bags to block migration.

Next, conduct a thorough visual inspection. Use a bright flashlight to examine seams, folds, cushions, and the underside of the frame. Look for live bugs, shed skins, and tiny dark spots (fecal stains).

After confirming presence, follow these steps:

  1. Remove and launder all removable fabrics.

    • Strip cushion covers, pillowcases, and any removable upholstery.
    • Wash at 120 °F (49 °C) for at least 30 minutes; then dry on high heat for a minimum of 30 minutes. Heat kills all life stages.
  2. Treat non‑removable components.

    • Apply a certified bed‑bug spray or dust (e.g., silica‑based or diatomaceous earth) directly to seams, crevices, and the frame.
    • Follow the product label for concentration, contact time, and safety precautions.
  3. Use heat‑based methods for the entire sofa.

    • Rent a professional portable heater or steam cleaner capable of reaching 130 °F (54 °C).
    • Heat the furniture for at least 90 minutes, ensuring the temperature penetrates deep layers.
  4. Vacuum thoroughly.

    • Employ a vacuum with a HEPA filter.
    • Pass over all surfaces, paying special attention to folds and joints.
    • Immediately seal the vacuum bag or empty the canister into a zip‑lock bag and discard it outdoors.
  5. Seal and monitor.

    • Cover the treated sofa with a tightly fitted mattress encasement or heavy‑duty plastic for two weeks.
    • Inspect daily for any surviving insects or new activity.
  6. Address the surrounding environment.

    • Wash nearby bedding, curtains, and clothing using the same high‑temperature protocol.
    • Treat baseboards, floor cracks, and adjacent furniture with the same insecticide or dust.
  7. Consider professional assistance if:

    • The infestation persists after two treatment cycles.
    • The sofa is heavily upholstered with hard‑to‑reach internal cavities.

Maintain a strict sanitation routine: vacuum regularly, reduce clutter, and limit the movement of the sofa until the problem is resolved. Continuous monitoring will confirm eradication and prevent re‑infestation.
