How to clean a sofa after bedbugs? - briefly
Vacuum the upholstery, then steam‑clean or launder removable covers at the highest safe temperature, and apply a certified insecticide to the frame and seams. Repeat the treatment after 7–10 days to destroy any newly hatched pests.
How to clean a sofa after bedbugs? - in detail
Eliminate bed‑bug infestations from a couch with a systematic approach that combines physical removal, targeted treatment, and preventive measures.
Begin by isolating the sofa. Move it away from walls and other furniture to prevent insects from migrating. Vacuum the entire surface, including cushions, seams, crevices, and the frame. Use a brush‑attachment to dislodge eggs and nymphs, then immediately empty the vacuum bag or canister into a sealed plastic bag and discard it outdoors.
Next, launder all removable covers, throws, and pillowcases. Set the washing machine to the hottest temperature the fabric can tolerate (minimum 120 °F/49 °C). Follow with a high‑heat dryer cycle for at least 30 minutes to kill any remaining stages.
Apply a residual insecticide labeled for indoor use on upholstery. Spray evenly, focusing on stitching, folds, and hidden areas. Allow the product to dry according to the manufacturer’s instructions before using the sofa again.
For non‑removable fabrics, use a steam cleaner capable of reaching 212 °F/100 °C. Slowly pass the steam over the entire surface, maintaining contact for at least 10 seconds per spot. The heat penetrates deep enough to destroy eggs and adult insects.
After treatment, encase the sofa in a zippered, breathable cover designed for pest control. Keep the enclosure on for at least two weeks, monitoring for any surviving bugs. During this period, avoid placing clothing, blankets, or pets on the furniture.
Finally, reduce the risk of reinfestation by:
- Decluttering the surrounding area to eliminate hiding places.
- Inspecting and treating adjacent furniture, carpets, and baseboards.
- Regularly vacuuming and washing fabrics.
- Maintaining low humidity levels, as dry environments deter bed‑bug development.
Following these steps ensures thorough decontamination of a couch and minimizes the likelihood of a recurring problem.
