How to chase a mouse out of a baseboard? - briefly
Set a humane trap or apply a mouse‑repellent (e.g., peppermint oil) at the baseboard opening, then seal all gaps once the rodent leaves. Eliminate food sources and maintain cleanliness to discourage re‑entry.
How to chase a mouse out of a baseboard? - in detail
A mouse that has taken shelter behind a baseboard can be expelled without harming the animal or the structure. Begin by confirming the rodent’s presence: listen for scratching, look for droppings, and inspect for gnaw marks. Once identified, isolate the area to prevent the mouse from escaping into other rooms. Close doors, seal openings larger than a quarter‑inch, and turn off lights in adjacent spaces to create a dark, confined zone.
Next, prepare a humane lure. Place a small amount of high‑protein food—peanut butter, cheese, or sunflower seeds—on a piece of cardboard or a shallow dish. Position the bait directly at the opening of the baseboard gap, ensuring the mouse can reach it without having to exit the concealed space.
While the bait is in place, create a gentle airflow that encourages movement toward the exit. Use a low‑speed fan set to blow air away from the baseboard, directing the scent of the bait toward the opening. The mouse will follow the scent trail and the slight breeze to the food source.
When the rodent emerges, capture it promptly. A snap‑trap with a soft covering, a live‑catch cage, or a sturdy cardboard tube can be used. Position the trap so the mouse must pass through the baited area to reach safety. Check the trap every few minutes to avoid unnecessary stress.
After capture, release the animal at least one mile from the residence, preferably in a wooded or field area, to reduce the likelihood of return. Finally, seal the baseboard gap to prevent future incursions. Use steel wool or copper mesh to fill the opening, then cover with caulk or expanding foam. Inspect surrounding walls and floors for additional entry points and repeat the sealing process as needed.
