How can I drive a mouse out of a wall? - briefly
Identify the entry point, place a snap or humane trap inside the wall cavity, monitor until capture, then seal all gaps with caulk or steel wool to prevent future intrusion.
How can I drive a mouse out of a wall? - in detail
Identify the opening through which the rodent entered the structure. Inspect baseboards, electrical outlets, and any gaps around piping. Seal each opening with steel wool, caulk, or expanding foam to prevent re‑entry.
Create a pathway that encourages the animal to leave the cavity:
- Locate the approximate position of the mouse by listening for movement or using a flashlight through any accessible hole.
- Insert a small piece of cardboard or a thin wooden strip into the opening, forming a ramp that leads outward.
- Place an attractive food source—such as peanut butter, cheese, or sunflower seeds—at the far end of the ramp.
Set up capture devices inside the wall cavity:
- Snap traps positioned near the suspected nesting area, baited with the same food.
- Live‑catch traps placed on the ramp, allowing the mouse to enter but not exit without human assistance.
Monitor the traps regularly. If a live trap is triggered, wear gloves and release the animal at least 100 feet from the building, preferably in a wooded area.
After removal, treat the interior to deter future infestations:
- Sprinkle rodent‑repellent powder (peppermint oil, mothballs, or commercial deterrent) along the cavity.
- Install a one‑way exclusion device that permits exit but blocks re‑entry.
- Conduct a thorough cleaning of any droppings or nesting material using a disinfectant solution.
If signs of activity persist or the infestation appears extensive, contact a licensed pest‑control professional to assess structural damage and apply appropriate control measures.
