What should you do if rats have chewed through the floor? - briefly
First, locate and seal every opening the rodents used, then repair the damaged floor section with suitable material and disinfect the area. Next, deploy traps or hire a licensed pest‑control professional to eradicate the infestation and prevent future damage.
What should you do if rats have chewed through the floor? - in detail
If rodents have penetrated the subfloor, immediate action is required to prevent structural damage, health hazards, and further infestation.
First, isolate the affected area. Shut off any utilities that could be compromised, such as electricity or water lines running beneath the floor, to eliminate safety risks.
Next, assess the extent of the damage. Remove loose debris, damaged panels, and any insulation that has been gnawed. Use a flashlight to inspect the joists and underlying structures for signs of weakening, mold, or additional chew marks.
After the inspection, implement a two‑step remediation plan:
-
Repair and reinforce
- Cut out compromised sections of the subfloor, leaving a margin of at least two inches beyond visible damage.
- Replace removed boards with pressure‑treated lumber or moisture‑resistant panels, securing them with corrosion‑resistant screws.
- Apply a metal mesh or hardware cloth barrier along the underside of the repaired area to deter future gnawing.
- Seal all gaps, cracks, and openings with steel wool combined with expanding foam or caulk designed for pest exclusion.
-
Control the infestation
- Set snap traps, electronic traps, or live‑catch traps in the vicinity, positioning them along walls and near known travel routes.
- Deploy bait stations containing anticoagulant or non‑anticoagulant rodenticide, following label instructions and local regulations.
- Consider hiring a licensed pest‑management professional for integrated pest‑management (IPM) services, especially if the population appears extensive.
Finally, restore the finished flooring. Install a vapor barrier if moisture is a concern, then lay the chosen flooring material—hardwood, laminate, tile, or carpet—according to manufacturer guidelines. Conduct a post‑repair inspection to verify that no new entry points exist and that the structural integrity meets building codes.
Regular monitoring, sealing of exterior entry points, and maintaining a clean environment will reduce the likelihood of recurrence.
