How can you drive a mouse out of drywall? - briefly
Identify the entry point in the wall cavity and set snap or live‑catch traps with peanut‑butter bait at that location; monitor until the rodent is captured. Seal all gaps with steel wool and caulk to prevent future intrusion.
How can you drive a mouse out of drywall? - in detail
Identify the exact location of the rodent within the wall. Look for fresh droppings, gnaw marks, or rustling sounds. Mark the spot with tape or a pencil for reference.
Seal every possible entry point. Inspect the exterior and interior of the building for gaps around pipes, vents, and utility lines. Use steel wool combined with caulk, expanding foam, or cement to close openings that are larger than a quarter‑inch.
Choose an appropriate removal method:
- Live‑catch traps: Place snap‑type or cage traps near the marked area. Bait with peanut butter, oatmeal, or dried fruit. Check traps twice daily and release captured animals at least one mile from the property.
- Snap traps: Position for immediate kill. Use the same bait, set the trigger sensitivity to a light touch, and place traps perpendicular to the wall surface.
- Ultrasonic repellers: Install devices inside the wall cavity through a small drilled hole. Emit high‑frequency sound that rodents find uncomfortable. Replace units every six months to maintain effectiveness.
- Scent deterrents: Apply peppermint oil, mothballs, or ammonia on cotton balls and tuck them into the cavity. Refresh every 48 hours until activity ceases.
- Professional extermination: If traps fail after three days, contact a licensed pest‑control service. They can apply rodenticides or fumigation safely and verify that all ingress points are sealed.
Maintain a clean environment to discourage re‑infestation. Store food in sealed containers, remove crumbs, and keep garbage bins closed. Regularly inspect the drywall for new signs of activity and repeat the sealing process promptly.
