Short answer: the garage is the easiest room of a Buffalo house to enter and the quietest to live in. Door corner gaps you can see daylight through, stored seed and pet food, and weeks without disturbance. Most garage mouse problems are a sealing and storage fix. The catch is that the garage shares walls with the house, so it has to be checked as one building.
An overhead garage door almost never seals at the corners, and the gap left there is mouse-sized by design tolerance, not by damage. Add the side door with a worn sweep, the gap where the garage meets the house foundation, and stored food: bird seed, grass seed, pet food in the bag it came in. A garage offers a mouse food, cover and a door it does not have to gnaw. In postwar Cheektowaga and Tonawanda housing, this is the single most common entry story we hear.
The wall between the garage and the house is full of passages: plumbing, wiring, duct runs, and the attic above the garage often connects to the house attic with no real barrier. Mice that winter in the garage explore all of them. The signs that the problem has crossed are specific: droppings in the room adjoining the garage, sounds in that wall, and activity in the attic above the living space rather than above the garage. Our signs guide helps separate a contained garage issue from a house-wide one.
An inspection names the animal, the scale of the problem and the entry points, with the price for each part in writing.
A garage-only problem caught in its first season is mostly the list above plus trapping, and it is some of the cheapest rodent work there is. It stops being garage-only when droppings appear in the house, when the attic above living space shows activity, or when the same garage problem has returned two falls running despite new door seals: at that point something else is open, and the mouse program starts with an inspection of the whole shell rather than another round of garage traps.
Usually the shared wall or the attic connection: the door was one entry, not the only one. The other regulars are the foundation gap behind the garage's rear wall and utility lines entering through the garage. An inspection of the whole shell finds the open one.
Mostly, with one watch-out: mice nest in engine bays and chew vehicle wiring and insulation, especially in cars that sit. If the car is driven daily the risk is low. A stored car in a mouse-active garage deserves a look under the hood each spring.
Not at any strength you can maintain. The smell fades, the mice habituate, and the gap is still open. Seal the gap and store the food properly; scents are not a barrier and never have been.

Sounds in the walls, droppings in the wrong place, a smell that will not air out. The inspection names the animal and the entry points before you spend anything on treatment.
