Bee's housing stock shapes exactly where rodents get in. Housing here ranges from historic farmhouses to newer construction, with basements standard throughout for winter protection. Combined with the area's climate — a continental climate where both summer heat and winter cold are taken seriously, standard for the Corn Belt — 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.
