What should I do if there are mice in the basement? - in detail

Discovering rodents in a cellar requires immediate, systematic action. Begin with a thorough inspection to locate activity signs—droppings, gnaw marks, nests, and pathways. Follow the inspection with these steps:

  1. Eliminate food sources

    • Store all food in airtight containers.
    • Remove pet food overnight.
    • Clean spills and crumbs promptly.
  2. Seal entry points

    • Examine walls, foundation, pipes, and vents for gaps as small as a quarter‑inch.
    • Use steel wool combined with expanding foam or cement to block openings.
    • Install door sweeps and weather stripping on basement doors.
  3. Deploy control devices

    • Place snap traps along walls where droppings are concentrated; position them perpendicular to the wall with the trigger end facing the wall.
    • For larger infestations, consider electronic or live‑catch traps, ensuring humane disposal.
    • Bait stations should contain anticoagulant or bromadiolone pellets, positioned out of reach of children and pets; follow label instructions for placement density (approximately one bait per 100 sq ft).
  4. Maintain sanitation

    • Vacuum or sweep debris daily.
    • Dispose of waste in sealed bags.
    • Keep the basement dry; fix any leaks, and use a dehumidifier if humidity exceeds 50 %.
  5. Monitor and adjust

    • Check traps every 24 hours, replace baits as needed, and record capture locations.
    • Continue surveillance for at least two weeks after the last capture to confirm eradication.
  6. Consider professional assistance

    • If activity persists despite these measures, contact a licensed pest‑control operator.
    • Professionals can perform structural assessments, apply rodenticides safely, and provide a long‑term exclusion plan.

Following this protocol eliminates the current infestation and reduces the likelihood of future rodent intrusion.
