The garage can be a separate activity area
A garage holds the things a household uses less often: boxes, pet-food bags, and equipment against a wall. Those spaces can provide cover or accessible food. A mouse seen there does not prove that every room inside is occupied by rodents. An assessment should establish the extent of the activity, including whether there are fresh signs beyond the door to the house.
An animal removed is not an opening repaired
Control addresses the animals present. Exclusion addresses the routes that may let more enter. These are connected parts of a rodent plan, but one does not automatically complete the other. Door thresholds, service-line openings, and damaged building edges need evaluation at the actual property. A visible gap may be relevant without explaining every sign. The assessment should connect proposed repairs with the evidence rather than simply close the easiest opening to find.
Fresh evidence tells the next part of the story
Chewed packaging or nesting material gives an inspector more than a vague report of movement. A monitoring record should distinguish existing signs from new activity. That makes it possible to evaluate control and decide whether an unresolved route needs attention. Keep mice and rats open as identification questions rather than assuming the animal from a sound alone.
