Petoskey's housing stock shapes exactly where rodents get in. A mix of established Grand Rapids-area neighborhoods and more rural, forest-adjacent homes farther north, most with basements built for heavy snow load. Combined with the area's climate — a four-season climate defined by lake-effect weather, colder and snowier than southeast Michigan, especially in the Upper Peninsula — rodents seeking shelter from weather extremes make a beeline for any accessible gap.
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.
