Mice and rats are opportunists, and Chino Valley properties give them plenty of opportunity. Housing ranges from historic mining-town construction to newer builds on wooded acreage, with crawl spaces and partial basements far more common than in the valley below. Once inside a wall void or attic space, they're difficult to remove without sealing the entry point that let them in.
Exclusion is the core of effective rodent control: finding and sealing every gap a mouse or rat could use to get inside, since traps alone just remove the current population without stopping the next one. We pair exterior sealing with interior trapping or bait stations, then follow up to confirm the problem is resolved.
