Rodent pressure in Mountlake Terrace tracks closely with the season and the housing stock. Founded in 1949 as a postwar veteran housing development of small cinder-block/ranch homes; retains many original 1950s-60s houses alongside newer infill. 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.
