Seal any openings in the siding and foundation, place snap traps or ultrasonic deterrents in the cavity, and eliminate accessible food and water sources.
How can I get rid of mice under the siding? - in detail
Eliminating rodents that have taken residence beneath exterior siding requires a systematic approach that combines inspection, exclusion, population control, and ongoing prevention.
First, conduct a thorough visual assessment. Look for signs such as gnaw marks on wood, droppings, disturbed insulation, and small holes near the base of the wall. Use a flashlight and a mirror to examine hard‑to‑reach areas. Identify every opening that could serve as an entry point, including gaps around vent pipes, utility lines, and the bottom edge of the siding.
Next, seal all identified openings. Apply steel wool or copper mesh to fill small cracks, then cover with a durable sealant such as silicone caulk or expanding foam. For larger gaps, install metal flashing or hardware cloth (minimum ¼‑inch mesh) secured with screws. Ensure the bottom of the siding is fitted tightly to the foundation; add a drip cap or trim if necessary.
After exclusion, reduce the existing mouse population. Choose one or more of the following methods:
- Snap traps placed along walls, behind the siding, and near suspected runways. Use a bait such as peanut butter or dried fruit. Position traps perpendicular to the wall, with the trigger end facing the mouse’s travel path.
- Electronic traps that deliver a rapid, humane kill. Place them in concealed locations to prevent accidental contact.
- Bait stations containing anticoagulant or non‑anticoagulant rodenticide. Follow label instructions, secure stations to prevent access by children or pets, and monitor regularly.
If traps and bait stations are insufficient, consider a professional pest‑control service. Certified technicians can apply targeted fumigation or dust treatments that penetrate the concealed space without damaging the siding.
Finally, implement a maintenance routine to deter future infestations. Keep the exterior clear of debris, firewood, and dense vegetation that offers shelter. Trim back shrubs that touch the house. Inspect the siding annually, especially after severe weather, and repair any new cracks promptly. Regularly check for fresh droppings or gnaw marks, and act immediately if they appear.
By integrating careful inspection, effective sealing, appropriate trapping or baiting, professional assistance when needed, and consistent upkeep, you can eradicate the current rodent problem and prevent recurrence beneath the siding.
