Application Method

Perform comprehensive exclusion to prevent rodent entry into structures. Seal all openings 1/4 inch or larger (mice) or 1/2 inch or larger (rats) using appropriate materials: copper wool or stainless steel mesh stuffed into gaps before sealing, 1/4 inch hardware cloth over vents and larger openings, sheet metal for edges and corners rodents may gnaw, concrete/mortar for foundation gaps, expanding foam for irregular voids (after stuffing with mesh), metal kick plates on door bottoms, and escutcheon plates around pipes. Target common entry points: gaps under doors, holes around utility penetrations, broken foundation vents, gaps in siding, roof/soffit intersections, and gaps where dissimilar materials meet. Advanced proofing addresses complex structural issues requiring carpentry skills, custom fabrication, and multiple materials.

Timing

Perform after rodent population controlled through trapping and baiting. Best done during dry weather for proper sealant curing.

Frequency

One-time comprehensive exclusion. Inspect quarterly for new gaps or damage to repairs. Repair immediately if rodents breach exclusion work.

Preparation Required

Complete thorough inspection identifying all entry points. Create exclusion plan prioritizing entries. Have variety of materials and tools ready. May need to coordinate with general contractor for complex repairs. Confirm rodents eliminated before sealing.

Follow-up Required

Inspect all exclusion work to verify completeness. Monitor for rodent activity indicating breach. Provide customer with documentation of all exclusion work completed. Warranty exclusion work and repair breaches.

Safety Precautions

  • Use power tools safely
  • Work safely on ladders and roofs
  • Wear gloves when handling metal materials
  • Do not seal rodents inside structure
  • Ensure proper building ventilation maintained
