What should I do if there is a mouse under the baseboard? - briefly
Seal any gaps around the baseboard, place snap or live‑catch traps near the suspected entry, and contact a professional pest‑control service if the problem persists.
What should I do if there is a mouse under the baseboard? - in detail
If a rodent is discovered beneath the baseboard, begin with immediate containment. Turn off lights in the affected area, close doors, and seal any openings that could allow the animal to escape into other rooms. Wear disposable gloves and a mask to protect against droppings and urine.
Next, locate the exact entry point. Inspect the perimeter of the baseboard for gaps, cracks, or loose trim. Use a flashlight to trace any gnaw marks or fresh droppings that indicate the path of travel. Mark each opening with painter’s tape for later reference.
Choose an appropriate capture method. Options include:
- Snap traps positioned perpendicular to the wall, baited with peanut butter, chocolate, or dried fruit. Place traps 1–2 inches from the identified gap.
- Live‑catch traps placed in the same manner, checked every few hours to prevent undue stress on the animal.
- Glue boards as a last resort, recognizing they cause prolonged suffering and are less humane.
Set traps and monitor them for 24–48 hours. Once captured, release live specimens outdoors, at least 100 feet from the residence, or dispose of dead rodents according to local regulations.
After removal, seal all entry points. Apply steel wool or copper mesh to fill gaps, then cover with caulk or expanding foam. Replace damaged sections of baseboard with new trim, ensuring a tight fit against the wall.
Implement preventative measures to deter future incursions:
- Store food in airtight containers; clean crumbs and spills promptly.
- Reduce clutter near walls, including cardboard boxes and paper piles.
- Maintain exterior landscaping by trimming vegetation away from the foundation and clearing debris that could shelter rodents.
- Install door sweeps and weather stripping on exterior doors.
Finally, conduct a follow‑up inspection after one week. Verify that no new activity signs appear and that all seals remain intact. Regular maintenance of the perimeter and interior will minimize the risk of recurrence.
