How to get rid of a ground mouse? - in detail
A ground‑level mouse can be detected by droppings, gnaw marks, and nesting material near floor vents, baseboards, or under appliances. Confirm the presence before initiating control measures.
Seal all potential entry points. Inspect the foundation, crawl spaces, and exterior walls for gaps larger than ¼ inch. Apply steel wool or copper mesh to narrow openings, then cover with silicone caulk or expandable foam. Install door sweeps and weatherstripping on all exterior doors.
Implement trapping as the primary reduction method. Use snap traps or electronic traps positioned perpendicular to walls, with the trigger end facing the wall. Place traps 1–2 feet apart along established runways. Check traps daily, dispose of captured rodents, and reset traps until no activity is observed for several days.
If baiting is required, select anticoagulant rodenticides approved for indoor use. Place bait stations in tamper‑resistant containers, located behind appliances, under sinks, and in concealed corners. Follow label instructions regarding dosage and safety precautions to protect non‑target species.
Maintain a clean environment to discourage re‑infestation. Store food in sealed containers, promptly clean spills, and eliminate clutter that provides shelter. Regularly empty trash cans, and keep compost bins sealed. Conduct routine inspections of the sealed entry points and replace deteriorated materials.
When infestation persists despite these actions, engage a licensed pest‑control professional. They can perform comprehensive assessments, apply advanced control techniques, and provide ongoing monitoring to ensure long‑term eradication.
