A mouse is scratching under the floor in an apartment; what should I do? - in detail
If you detect a rodent scurrying beneath the floor of your residence, immediate action is required to prevent damage and health risks.
First, locate the source of activity. Follow the scratching sounds to the nearest wall or vent, and inspect for gnaw marks, droppings, or small holes. Use a flashlight to examine baseboards, under appliances, and behind cabinets.
Next, eliminate access points. Seal cracks, gaps around pipes, and openings around doors with steel wool and caulk. Install door sweeps and repair any damaged wiring or insulation that could serve as a pathway.
Implement control measures. Choose one or more of the following options:
- Snap traps baited with peanut butter or dried fruit, placed perpendicular to walls where activity is observed.
- Live‑catch traps, positioned similarly, for humane removal.
- Electronic traps that deliver a quick, lethal shock.
- Poison baits, only if local regulations allow and pets or children are absent; place in tamper‑resistant stations.
Maintain a clean environment to reduce attractants. Store food in sealed containers, promptly clean crumbs and spills, and regularly empty trash bins. Reduce clutter that could provide shelter.
If the infestation persists after several days of trapping and sealing, or if structural damage appears (e.g., gnawed wiring or flooring), contact a licensed pest‑control professional. They can conduct a thorough inspection, apply rodenticides safely, and recommend long‑term prevention strategies.
Finally, monitor the situation for at least two weeks. Check traps daily, replace baits as needed, and re‑inspect sealed openings to ensure they remain intact. Continuous vigilance prevents re‑infestation and safeguards the property.
