Most people think if they don't see a mouse, they don't have a mouse. In our experience it's closer to the opposite: by the time you see one in the open, the hidden population is established. Rodents are built for concealment, and Utah homes offer them a lot of places to use it.
It takes almost nothing to get in
All the invitation a mouse needs is a crack in the foundation, an open vent, or a loose attic hatch. Once inside, they pick harborage by three rules: dark, undisturbed, close to food or nesting material.
Where we actually find them
The attic tops the list: insulation makes premium nesting material, and nobody visits. We routinely find nests tunneled into attic insulation, droppings hidden behind wall insulation, and mice living inside pantry walls, inches from a food supply they raid at night. Garages, crawl spaces and the voids under kitchen cabinets round out the usual circuit.
Checking under the sink isn't an inspection
If you're only checking under the sink, you're missing 90% of the problem. The evidence that matters sits in places a flashlight-and-a-glance check never reaches: rub marks on rafters, droppings behind insulation, gnawing at the attic hatch. That's why our inspections run top to bottom: attic, walls, crawl space, garage, exterior.
If something feels off (noises, a smell, chewed packaging), trust it. A full-home inspection is free, and if we find activity we'll map every harborage and entry point before recommending a treatment plan.
