To protect your home from mice, it’s essential to eliminate any potential entry points and remove attractions like food sources or cozy hiding spots. Here are some steps you can take:

  1. Seal Entry Points
    • Close Gaps: Mice can squeeze through tiny spaces as small as a dime. Inspect your home for small holes or gaps in walls, floors, foundations, and around pipes.
    • Use Steel Wool: Steel wool is excellent for filling small gaps, as mice can’t chew through it. Combine steel wool with caulk for extra security.
    • Concrete Patching: For larger holes and cracks, use concrete patch to fill them in completely.
  2. Secure Doors and Windows
    • Weather Stripping: Install weather stripping around doors and windows to seal any small gaps. This also helps with insulation and prevents drafts.
    • Door Sweeps: Add door sweeps to the bottom of exterior doors, preventing mice from squeezing underneath.
  3. Cover Vents and Chimneys
    • Vent Covers: Ensure all vent openings are covered with metal mesh that has small enough holes to prevent mice from getting through.
    • Chimney Caps: Install chimney caps to stop mice from climbing in through the top of your chimney.
  4. Keep the Perimeter Clear
    • Trim Vegetation: Mice often use branches and shrubs as pathways to get onto roofs or through windows. Keep trees and bushes trimmed back at least three feet from the house.
    • Clear Debris: Piles of leaves, wood, or other debris provide shelter and hiding spots for mice near your home. Keep the area around your home clear to deter them.
  5. Protect Food Sources
    • Store Food Properly: Keep all food, including pet food, in sealed containers to prevent mice from smelling it and being attracted indoors.
    • Clean Up Spills: Mice are constantly on the hunt for food. Clean up crumbs, spills, and food stains promptly, especially in areas like the kitchen and dining room.
  6. Reduce Hiding Places Indoors
    • Declutter: Mice love hiding in cluttered spaces. Keep areas like basements, attics, and garages tidy and organized.
    • Store Items in Plastic Containers: Use plastic containers with tight lids instead of cardboard boxes, as mice can easily chew through cardboard.
  7. Regularly Inspect Pipes and Wires
    • Check Pipe Openings: Mice often use plumbing or wiring as pathways. Inspect where pipes and wires enter the home, and seal gaps around these entry points.
    • Install Rodent Guards: For exposed pipes or wires, especially outside the house, install rodent guards to prevent climbing.
  8. Limit Water Sources
    • Fix Leaks: Mice can survive on very little water, but fixing leaky faucets or pipes reduces their access to moisture.
    • Outdoor Water Sources: If you have birdbaths or pet water bowls outside, keep them far from the house to avoid attracting mice.
