Rodent pressure in Glen Echo tracks closely with the season and the housing stock. Dense rowhouse and multi-family housing in the urban core, alongside single-family suburban homes further out, most with basements. 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.
