Seal all openings, set appropriate traps or bait stations, and keep the area dry and clutter‑free to discourage rodents. Conduct routine inspections and refresh bait to maintain effective control.
How to treat a basement for mice? - in detail
A thorough approach begins with a complete inspection. Walk the perimeter, check walls, floor joists, and utility openings for gaps larger than a quarter‑inch. Use a flashlight to locate droppings, gnaw marks, and nesting material. Mark each potential entry point for later sealing.
Seal every opening. Apply steel wool or copper mesh to small cracks, then cover with expanding polyurethane foam or cement. For larger gaps, install hardware cloth or metal flashing secured with screws. Repair damaged drywall, baseboards, and vent covers.
Implement a trapping program. Choose snap traps for immediate kill, placing them perpendicular to walls with the trigger end facing the wall. Position traps at least 10‑12 inches apart along known runways. Use bait such as peanut butter, dried fruit, or commercial rodent lure. Check traps daily, dispose of captured mice, and reset with fresh bait.
If a poison approach is required, use enclosed bait stations to prevent accidental exposure to non‑target animals. Follow label instructions for dosage and placement, positioning stations near walls and away from food preparation areas.
Maintain sanitation. Remove all food sources, store items in sealed containers, and clean up crumbs and spills promptly. Reduce clutter that offers hiding places; store boxes on pallets off the concrete floor. Ensure garbage bins have tight‑fitting lids and are emptied regularly.
Establish ongoing monitoring. Install passive infrared sensors or motion‑activated cameras to verify activity levels. Replace or relocate traps based on observed movement patterns. Keep a log of captures, locations, and dates to identify trends.
Consider professional pest‑control services if infestations persist despite these measures. Experts can perform rodent-proofing, apply targeted baits, and provide a warranty for continued protection.
