Argillite's housing stock shapes exactly where rodents get in. Housing here is often built into hillside terrain, ranging from historic rural homes to more modest recent construction. Combined with the area's climate — a climate typical of Appalachian foothill country, with more precipitation and cooler temperatures at elevation — 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.
