Hales Corners's housing stock shapes exactly where rodents get in. Housing spans historic Milwaukee-area homes to newer Madison-area subdivisions, with basements throughout. Combined with the area's climate — a continental climate with a full range of seasonal extremes, defining life throughout the year here — 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.
