Rodent Trapping and Structural Exclusion Fort Collins

Rodent activity in Larimer County escalates rapidly between late September and November as temperatures drop along the Front Range, driving deer mice and house mice inward toward foundation heat. In historic neighborhoods like Old Town and City Park West, older stone or brick foundations frequently exhibit mortar breakdown and unsealed floor joists that grant rodents direct subfloor access. Modern developments such as Bucking Horse, Rigden Farm, and Sidehill frequently present builder-gap entry points, including uncollared HVAC refrigerant lines, gaps behind synthetic stucco weep screeds, and weathered garage weatherstripping. Near water corridors and natural spaces like Warren Shores, Fossil Creek, and the Cache la Poudre River, continuous rodent populations make exterior chemical baiting an incomplete solution that risks secondary poisoning to local raptors and family pets.

Structural exclusion is the definitive technical countermeasure to standard poison baiting. Rather than relying on exterior rodenticide boxes that leave pests to die inside crawlspaces or wall voids, Drevano Exterminators secures the building envelope. Technicians patch crawlspace air vents using 19-gauge galvanized 1/4-inch hardware cloth, seal pipe and conduit voids using high-density copper wire mesh paired with elastomeric sealant, and reinforce chewed garage-door astragals with steel-embedded rubber sweeps. While an exterior poison program requires perpetual monthly billing to maintain chemical barriers, physical structural exclusion halts immigration entirely by eliminating the physical pathways rodents require to cross the exterior boundary.

Interior remediation operates through mechanical capture rather than loose poisons. Snap traps secured within tamper-resistant utility boxes are deployed along active wall runs, attic trusses, and drop ceilings away from pets and children. In neighborhoods with high slab elevations like Registry Ridge and Huntington Hills, attics frequently harbor the primary travel runs. Trapping protocols follow a numbered execution model: 1. Complete perimeter elevation inspection to map every gap larger than a 1/4-inch pencil width. 2. Exterior installation of heavy-gauge metal barriers across all identified entry points. 3. Placement of mechanical trapping stations in attic and basement transit pathways. 4. Resetting and retrieval visits conducted within 3 to 5 business days until consecutive zero-catch monitoring confirms complete clearance.
