What should be done if mice are under the floor? - in detail

Mice living beneath a floor present health risks and structural damage. Immediate action involves three phases: assessment, elimination, and prevention.

1. Assessment

   • Locate entry points by inspecting gaps around baseboards, utility openings, and pipe penetrations.
   • Look for droppings, gnaw marks, and burrow entrances in the subfloor cavity.
   • Use a flashlight and a flexible inspection camera to confirm activity without disturbing the rodents.

2. Elimination

   • Seal all identified openings with steel wool, metal mesh, or expanding foam rated for pest control.
   • Deploy snap traps or electronic kill traps directly in the subfloor area; position them perpendicular to walls where mice travel.
   • For extensive infestations, apply a professional-grade rodenticide in bait stations, ensuring compliance with local safety regulations.
   • After capture or kill, remove carcasses and clean the area with a disinfectant solution containing at least 1 % bleach to eliminate pathogens.

3. Prevention

   • Install a continuous metal or cement barrier along the perimeter of the floor joists to block future ingress.
   • Maintain a moisture‑free environment; fix leaks and improve ventilation to deter nesting.
   • Store food and waste in sealed containers; avoid leaving crumbs or spills in adjacent rooms.
   • Schedule quarterly inspections to verify that seals remain intact and that no new signs of rodent activity appear.

By following these steps—identifying access routes, removing the current population, and establishing durable barriers—homeowners can eradicate the problem and safeguard both the building’s integrity and occupants’ health.
