Cresskill's housing stock shapes exactly where rodents get in. Dense multi-family buildings and rowhomes throughout the older cities, alongside single-family postwar suburban homes further out, most with basements. Combined with the area's climate — a four-season climate with real winter cold and snow, and hot, muggy summers — 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.
