What to do if there are mice in the basement? - briefly
Seal all gaps and cracks in the foundation and walls, then deploy snap traps or live‑catch traps along walls and near known activity, using bait such as peanut butter. Keep the basement clean, store food in sealed containers, and monitor traps regularly to ensure complete removal.
What to do if there are mice in the basement? - in detail
Mice in a basement require immediate, systematic action to prevent damage and health risks.
Identify entry points. Walk the perimeter, inspect walls, floor joints, utility openings, and vents. Seal gaps larger than a quarter‑inch with steel wool, caulk, or concrete patch.
Eliminate food sources. Store all items in airtight containers, remove pet food, and clean spills promptly. Dispose of garbage regularly and keep trash bins sealed.
Set up monitoring and control devices.
- Snap traps: place along walls, behind objects, and near suspected pathways. Use bait such as peanut butter or dried fruit.
- Live‑catch traps: position in the same locations; release captured rodents at least five miles from the property.
- Electronic traps: deploy where power is available; they deliver a lethal shock instantly.
Deploy traps in multiple rows, spacing them 12–18 inches apart. Check traps daily, remove dead rodents, and reset with fresh bait.
Consider professional extermination if infestation persists beyond a few weeks, if structural damage is evident, or if disease concerns arise.
Maintain a preventive regimen. Conduct quarterly inspections, keep humidity low with a dehumidifier, and ensure proper ventilation to discourage nesting. Regularly clean the area, removing debris and clutter that could provide shelter.
Document actions taken, including dates of sealant applications and trap placements, to track effectiveness and inform future interventions.
