Seal all potential entry points, then place snap traps or bait stations to capture the rodent; if the problem continues, hire a licensed pest‑control professional.
A mouse is running in the apartment; what should be done? - in detail
A small rodent has entered a residential unit and is actively moving through rooms. Immediate action should focus on containment, elimination, and prevention of future incursions.
First, isolate the animal to limit damage and reduce health risks. Close doors to rooms where the creature is not present, and block obvious pathways with towels or cardboard. Turn off lights in affected areas to encourage the mouse to seek darkness, making it easier to capture.
Second, choose an appropriate removal method. Options include:
- Snap traps placed perpendicular to walls, baited with peanut butter or small pieces of cheese. Position traps near walls, behind furniture, and in corners where droppings are visible.
- Live‑catch traps that allow release outdoors, at least 100 meters from the building to prevent re‑entry.
- Electronic traps that deliver a quick lethal shock, reducing mess.
Select the method that aligns with personal ethics and local regulations. After placement, check traps daily and dispose of caught rodents according to sanitary guidelines.
Third, identify and seal entry points. Conduct a thorough inspection of the building envelope, paying special attention to:
- Gaps around pipe penetrations, vents, and electrical conduits.
- Cracks in foundation walls, baseboards, and window frames.
- Openings behind appliances, such as refrigerators and dishwashers.
Use steel wool combined with caulk for small holes, and install metal mesh or expanding foam for larger gaps. Replace damaged weather stripping on doors and windows.
Fourth, improve sanitation to remove attractants. Store food in airtight containers, clean crumbs from countertops, and empty garbage bins regularly. Eliminate standing water sources by fixing leaks and drying damp areas, as moisture attracts rodents.
Fifth, monitor the situation for several weeks after intervention. Deploy non‑lethal monitoring stations—such as glue boards placed out of reach of children and pets—to verify that activity has ceased. If signs of recurrence appear, consider professional pest‑control services that can perform comprehensive inspections and apply rodent‑proofing measures.
By following these steps—containment, targeted trapping, sealing of ingress points, sanitation, and ongoing monitoring—the infestation can be resolved efficiently while minimizing health hazards and property damage.
