What should you do if a rat gnaws wallpaper? - in detail
When a rodent begins to chew the wall covering, the first priority is to stop further damage and eliminate the source.
Inspect the affected area closely. Look for fresh gnaw marks, droppings, urine stains, or gnawing on nearby wiring and insulation. Identify any holes, cracks, or gaps that could serve as entry points, such as openings around pipes, vents, or baseboards.
Seal all potential access routes. Use steel wool, metal mesh, or expanding foam to block small cracks; apply cement or caulk to larger openings. Install a tightly fitting door sweep and check that window screens are intact.
Set traps or bait stations promptly. Choose snap traps, electronic traps, or live‑catch cages, placing them along walls, behind furniture, and near the damage. Bait with peanut butter, dried fruit, or commercially available rodent attractants. Check traps daily and dispose of captured animals according to local regulations.
After capture, clean the site thoroughly. Wear disposable gloves and a mask. Remove contaminated wallpaper sections, dispose of them in sealed bags, and disinfect the surrounding surface with a solution of bleach (1 part bleach to 10 parts water) or an EPA‑approved disinfectant. Allow the area to dry completely before proceeding.
Repair the wall. Apply a moisture‑resistant primer to the exposed plaster or drywall, then reinstall new wallpaper or paint with a durable, washable finish. Seal the repaired area with a clear coat if moisture is a concern.
Implement preventive measures to discourage future incursions. Keep food storage sealed, eliminate standing water, and maintain a clutter‑free environment. Trim vegetation away from the building’s exterior, and schedule periodic inspections of the building envelope.
If damage is extensive, gnawing has compromised electrical wiring, or the infestation persists despite these actions, contact a licensed pest‑control professional. They can conduct a thorough assessment, apply rodenticides safely, and recommend structural modifications to protect the property long‑term.
