What should you do if a mouse is scratching in the house? - in detail
When you hear rodent scratching sounds inside the home, immediate action reduces damage and health risks.
First, locate the activity. Follow the noise to walls, ceilings, or floorboards and look for signs such as droppings, gnaw marks, or shredded insulation.
Second, eliminate food sources. Store all pantry items in sealed containers, clean crumbs from surfaces, and keep pet food in airtight bins.
Third, block entry points. Inspect the exterior for gaps around pipes, vents, doors, and foundation cracks. Use steel wool, caulk, or metal flashing to seal openings larger than a quarter‑inch.
Fourth, set up control devices. Choose from snap traps, electronic traps, or multi‑catch live traps, placing them perpendicular to walls where the rodent travels. Bait with peanut butter, chocolate, or dried fruit. Replace traps daily and dispose of caught animals promptly.
Fifth, maintain a clean environment. Vacuum regularly, especially in hidden corners, and wash bedding, curtains, and upholstery that may harbor urine or feces.
Sixth, consider professional pest‑control services if the infestation persists, the mouse has entered structural cavities, or you encounter disease‑bearing species. Certified technicians can apply rodenticides safely and provide follow‑up inspections.
Finally, monitor the situation for several weeks. Continue checking traps, inspecting sealed gaps, and keeping food secured. Persistent absence of activity confirms successful eradication; any renewed signs require repeat of the above steps.
