Rodent pressure in Grammer tracks closely with the season and the housing stock. Older brick and wood-frame homes are common throughout this region, from Evansville's river neighborhoods to Bloomington's university district. A rodent problem rarely resolves with traps alone if the entry point stays open.
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.
