How to Handle Mice in Your Walls – The In-Depth Explanation

If you hear scurrying or scratching sounds in your walls, there’s a good chance you’re dealing with mice or another type of rodent. OK, so what next? How are you supposed to get them out? Successfully removing mice from your walls begins with locating their hiding spots, followed by strategic deployment of baits and traps, and finally using rodent exclusion strategies to keep them from coming back.

Eliminating a mouse infestation in your walls by yourself can be extremely challenging. It may only bring temporary relief because it fails to address the root cause of the problem. Fortunately, a professional rodent control expert can help. Professional rodent exterminators are often the best way to handle a rodent infestation inside the walls of your home because a pro can identify hidden entry points, apply safe, effective treatments, and ensure long-term protection.

What to Do About a Mouse Infestation in Your Walls

Confirm that you’re dealing with a rodent infestation by looking for other evidence, like tiny mouse droppings, which look like this.

Let’s say you’re in a state of high alert already — perhaps you’ve noticed tiny droppings in the house, or you’ve heard unusual noises. What should your next steps be? Here’s what we recommend:

  • Confirm you have an infestation: Search for additional evidence that you’re dealing with rodents, not a different kind of pest. Listen for clues in the walls. Scratching, gnawing, or scurrying sounds — especially at night — are a telltale sign. Also, look for signs outside the walls. Check around baseboards, attics, and crawl spaces for droppings, chewed materials, or greasy rub marks. Even if the rodents are hiding in the walls, they still need to come out for food and water.
  • Determine how they’re getting in: Just as important as trapping the living mice that are already inside, you need to determine where they’re coming from. More will keep coming in, and the size of the problem will only multiply. So, how did they enter your house from the outside? Find the access point. Rodents don’t magically appear. Do an inspection of the exterior of your home, looking for small gaps around pipes, cracks in the foundation, broken vents, or loose siding. If a hole is bigger than a dime, a mouse can probably squeeze through it.
  • Seal all entry points: Once you’ve found the entry points, seal them up so no more can get in. Use materials that rodents can’t chew through — like steel wool, metal flashing, or hardware cloth. Skip foam or caulk; they’ll chew right through it.
  • Place mousetraps strategically: Build a better mousetrap? They’ve been trying for over a hundred years, and snap traps are still one of the most effective ways to catch mice and rats. Place them near walls where you’ve heard activity. They’ll likely come out of the walls at some point while it’s calm and quiet in the house, so make sure the traps are ready. Bait them with something irresistible, like peanut butter. What about cheese? Mice will eat it, but it’s not one of their favorite foods.
  • Avoid using poisons: Rodenticides can create a new problem — dead rodents trapped in your walls. This can lead to an unbearable smell that’s difficult to get rid of. Stick to removal methods you can control.
  • Bring in a professional rodent exterminator: If the sounds continue or you suspect a larger infestation, it’s time to call a licensed pest control expert. Professionals can track the source, remove the problem, and help keep it from coming back.
