Mice are rustling in the wall, what should I do? - in detail

If you hear the sound of rodents moving within your interior walls, immediate action is required to prevent damage and health risks.

First, locate the entry points. Examine the exterior foundation, roof eaves, utility penetrations, and any gaps around pipes or cables. Use a flashlight to identify fresh gnaw marks, droppings, or shredded insulation. Seal each opening with steel wool, copper mesh, or expanding foam designed for pest control; these materials resist chewing.

Second, set up a containment system. Choose between snap traps, electronic devices, or live-catch cages, positioning them along the suspected travel routes—typically near walls, behind appliances, and close to food sources. Bait with high‑fat items such as peanut butter, sunflower seeds, or dried fruit. Replace bait daily and monitor trap activity for at least three nights.

Third, eliminate attractants. Store food in airtight containers, clean crumbs from countertops and floors, and empty garbage bins regularly. Repair any water leaks, as moisture draws rodents. Remove clutter that could serve as nesting material.

Fourth, assess structural damage. Inspect insulation, wiring, and wooden studs for chew marks or discoloration. Replace compromised sections promptly to avoid fire hazards and loss of energy efficiency.

Fifth, consider professional intervention. Certified exterminators can perform comprehensive inspections, apply rodenticides safely, and offer warranties on eradication efforts. Contact a licensed service if infestation persists after two weeks of self‑treatment or if you encounter signs of disease, such as droppings in high‑traffic areas.

Finally, implement preventive measures. Install door sweeps, maintain a clear perimeter around the building, and schedule periodic inspections, especially before colder months when rodents seek shelter. Consistent vigilance reduces the likelihood of recurrence.
