What should I do if a mouse is scratching on the floor? - in detail
When a small rodent produces scratching noises on the floor, immediate action is required to prevent damage, contamination, and potential health risks.
First, verify the activity. Observe the area for droppings, gnaw marks, or movement. Use a flashlight to scan baseboards, cabinets, and hidden spaces. If signs confirm the presence of a mouse, follow these steps.
-
- Store all edible items in airtight containers.
- Remove pet food bowls overnight.
- Fix any leaky pipes or faucets that could provide moisture.
-
Eliminate entry points
- Inspect walls, doors, and windows for gaps larger than ¼ inch.
- Seal cracks with steel wool and caulk or use expanding foam for larger openings.
- Install door sweeps and repair damaged screens.
-
Set up traps
- Choose snap traps for rapid kill, placing them perpendicular to walls where the rodent travels.
- Bait with peanut butter, chocolate, or dried fruit.
- For humane capture, use live‑catch traps, checking them at least twice daily to prevent suffering.
-
Apply deterrents
- Sprinkle peppermint oil, dried lavender, or ultrasonic repellers in suspected routes.
- Replace with fresh deterrent material every few days.
-
Clean and disinfect
-
Monitor the situation
- Keep traps active for at least two weeks after the last capture.
- Re‑inspect entry points weekly and re‑seal any new openings.
If the infestation persists despite these measures, contact a licensed pest‑control professional. They can conduct a comprehensive inspection, apply rodenticides safely, and provide a long‑term exclusion plan.
