How to treat a sofa bedbug? - in detail
Bed bugs hide in seams, cushions, and fabric folds of a sofa. Confirm their presence by spotting live insects, shed skins, or small dark spots of feces on the upholstery and frame.
- Remove all removable covers and wash them at ≥ 60 °C.
- Vacuum the entire piece, paying special attention to crevices, stitching, and the underside of cushions. Empty the vacuum bag into a sealed plastic bag and discard it outdoors.
- Apply a residual insecticide label‑approved for indoor fabric surfaces. Follow the manufacturer’s dosage instructions, spray evenly, and allow the sofa to dry completely before use.
- For non‑chemical control, place the sofa in a sealed enclosure (e.g., a large plastic bag or a garage‑sized tent) and expose it to temperatures of 50 °C for at least 30 minutes, or to −18 °C for 48 hours. Use a calibrated thermometer to verify temperature.
- After treatment, repeat vacuuming and washing weekly for at least four weeks to capture any newly hatched insects.
If infestation persists after two treatment cycles, enlist a licensed pest‑management professional. Professionals can apply heat‑treatment chambers, fumigation, or advanced insect growth regulators that are not available to consumers.
Prevent future incursions by inspecting second‑hand furniture before purchase, using protective mattress and sofa encasements, and maintaining a regular vacuum schedule. Reduce clutter around the seating area to eliminate additional hiding places.
