Do you hear odd noises coming from your walls, especially at night? It might indicate that mice have made your home their own, scurrying about unseen. These pests often go unnoticed until the sounds become too frequent to ignore. Mice are attracted to the warmth and protection our walls offer, but eliminating them from such hidden areas can be a challenge. Here, Griffin Pest Solutions experts share tips on how to remove mice from your walls and keep them out for good.

How Do You Know if Mice Are in Your Walls?

Mice are masters at concealing themselves and can easily squeeze into the tiniest gaps, which makes detecting an infestation challenging, especially if it’s occurring within your walls. Still, certain clues can reveal whether you’re facing a rodent problem. Be on the lookout for these signs of mice in your walls:

  • Scratching or Rustling Noises: Mice are active at night, and you may hear scratching, gnawing, or scurrying sounds coming from inside your walls, especially in the evening or early morning.
  • Droppings: Mice leave small, dark droppings in areas where they are active, such as near baseboards, in corners, or along their travel paths. These can sometimes be found near the edges of walls.
  • Gnaw Marks: Mice chew on various materials, including wood, wires, and insulation inside walls. You might notice gnaw marks around openings, baseboards, or entry points where they may have gained access.
  • Unpleasant Odors: A musty or urine-like smell can develop in areas where mice have been present for a while, especially if a mouse dies within the walls.
  • Nesting Materials: While hidden within walls, mice may build nests out of shredded materials like paper or insulation. If you discover nesting materials near cracks or openings, this could be a sign of mice inside your walls.
  • Holes or Gaps: Mice can chew their way through drywall or other materials to create entry points. Small holes or gaps along baseboards or wall surfaces may indicate their presence.

Why Do Mice Live in Walls?

Mice are infamous for invading homes and nesting within walls, causing damage and becoming a long-term nuisance. They enter through tiny holes, cracks, and gaps around baseboards, windows, air ducts, crawl spaces, and vents. Once inside, they retreat into the walls, which provide warmth, safety from predators, and an excellent place to hide. Mice can chew through insulation to build nests, staying concealed while foraging for food and water nearby. Knowing why mice are attracted to walls helps homeowners take steps to prevent a larger infestation.

Sealing Mice Entry Points

Sealing up potential entryways is essential for preventing mice from getting into your home. Here are some effective methods to help you rodent-proof your space: 

  • Inspect Your Home for Openings: Thoroughly check both the interior and exterior of your home for small gaps, cracks, or holes. Focus on areas around baseboards, air ducts, windows, the foundation, attic vents, and areas near plumbing or electrical lines. Look for signs of mouse activity, such as droppings or gnaw marks, to help pinpoint potential entry points.
  • Seal Small Gaps with Steel Wool and Caulk: For smaller holes, use steel wool, which mice cannot chew through. Press the steel wool into the gap and seal it with caulk to ensure a tight, durable closure.
  • Use Expanding Foam or Wire Mesh for Larger Holes: For bigger openings, apply expanding foam or cover them with wire mesh. These materials block entry while preventing mice from chewing their way back in.
  • Check and Reinforce Vulnerable Areas: Pay extra attention to vents, crawl spaces, and gaps around windows or doors. Reinforce these areas with weather stripping, caulk, or mesh as needed to eliminate potential entry points.
  • Regularly Monitor for New Openings: After sealing, periodically inspect your home for any new gaps or signs of mouse activity to ensure your home remains secure.

Effective Strategies for Trapping Mice

When dealing with a mouse infestation, employing effective trapping strategies is essential. Here are some key strategies to help you successfully catch and manage mice in your home:

  • Types of Traps: There are several types of traps you can use to catch mice. Snap traps are quick and effective, instantly killing mice upon contact. Glue traps capture mice for later removal, though they are less humane. For those seeking a humane option, live traps allow for the safe capture and release of mice.
  • Placement of Traps: To effectively catch mice, set traps along baseboards, near entry points, and in areas where mouse activity is visible. These locations are common pathways for rodents. Be sure to regularly check and reset the traps to ensure they remain effective and continue to capture any mice in the area.
  • Baiting Strategies: To lure mice out of walls, use foods like peanut butter, cheese, or seeds as bait, as these are highly attractive to rodents. Place the bait on traps positioned near suspected entry points, such as holes or cracks in baseboards. Since mice typically travel close to walls, it’s important to set the traps along their pathways. Be careful not to use too much bait, as this can allow mice to steal it without triggering the trap.

When DIY Methods Fail

Dealing with a rodent infestation can be incredibly frustrating. While DIY methods may catch a few mice, they usually aren’t effective against a larger problem. Mice can chew through drywall and wiring, slipping through small cracks, making trapping difficult. Telltale signs like droppings, gnaw marks or sounds from the crawl space or attic suggest a more serious issue. If these signs persist or you continue to catch mice in traps, it’s wise to consult a professional rodent exterminator.
