How to evict a mouse from the ceiling? - briefly
Seal all possible entry holes and place baited snap traps or a humane catch cage on the ceiling where the rodent travels. After capture, release the mouse at a distant location and reinforce the sealed openings to prevent re‑infestation.
How to evict a mouse from the ceiling? - in detail
Mice can enter attic spaces through gaps around vents, pipes, or roof joints. Locate the exact entry points by inspecting for gnaw marks, droppings, or nesting material. Use a flashlight and a mirror to view hidden corners without climbing into the cavity.
Gather the necessary equipment: snap traps or live‑catch traps rated for rodents, steel wool or copper mesh for sealing holes, a sturdy ladder, gloves, and a dust mask. Place traps along walls, near suspected pathways, and close to any food sources. Bait with peanut butter, sunflower seeds, or dried fruit for rapid attraction. Set traps at a slight angle so the trigger plate faces the wall, ensuring the mouse must push forward to activate.
If capture is not feasible, apply rodent‑deterrent substances such as peppermint oil or commercial ultrasonic emitters in the ceiling void. Position emitters at intervals of 6‑8 feet to cover the entire area. Combine deterrents with exclusion: seal all openings larger than ¼ inch using steel wool packed tightly, then cover with expanding foam or metal flashing for durability.
After removal, disinfect the space with a solution of 1 part bleach to 9 parts water. Dispose of trapped rodents in sealed bags and remove all bedding material. Install a permanent barrier—metal flashing around vents and pipe penetrations—to prevent future ingress. Conduct monthly visual checks for fresh droppings or new gnaw marks, and reset traps if activity resumes.
