Marne's housing stock shapes exactly where rodents get in. A blend of older river-valley homes and small-town construction typical of western Iowa. Combined with the area's climate — a humid continental climate with hot summers, cold winters, and somewhat drier conditions than eastern Iowa — 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.
