5 Steps to Get Mice Out of Your Attic

If you notice mice in your attic, you can take some steps to eliminate these pests:

Insulation Removal & Replacement

Insulation removal will help you detect hidden entry points mice use to enter your home. It will also eliminate any contaminants or waste mice leave behind. 

Rodents use their urine to mark their territory and help find their way home. Removing insulation and replacing it will eliminate their scent trails and keep them from coming back. 

Air Sealing

Air sealing refers to blocking air leaks in your house through gaps and cracks using tools like spray foam, rigid foam board, or foam covers. 

Infestation Control

Bait stations may help control a rodent infestation. Put baits in high activity spots, like along rafters. Check the bait boxes regularly to ensure they don’t need to be reset. Continue to add fresh bait until you no longer notice rodent activity. 

Once you eliminate the mice, remain proactive to prevent mice from returning to your attic. Use natural repellants, like peppermint or ammonia, to deter mice from returning.

Rodent Proofing: Identifying & Eliminating Entry Points

  • Crawlspace and basement
  • Attic
  • Vents
  • Gutters
  • Vinyl siding
  • Structure’s foundation
  • Roof
