How to Get Rid of Mice in Walls

Mice are destructive creatures with sharp teeth and claws that tear through drywall like paper. They are carriers of diseases such as salmonella and the hantavirus. If they get into your kitchen or bathroom, they can contaminate your food and water supplies with their droppings and urine. If you have a mouse problem, the best way to get rid of them is to trap them and remove them from your home.

Why do mice get into walls anyway?

Mice can fit through almost any opening in your home, which includes utility pipes, gas lines, cable networks, ductwork, and dryer vents since these holes are usually at least as big as a dime. Once they’ve entered, they find a warm, dry, safe place filled with fluffy insulation that’s ideal for nesting and hiding.

Mice are drawn to walls for many of the same reasons cats do, including safety and comfort. Because they have poor eyesight, they must have a haven. They rely on their whiskers as feelers, and since mouse edges are easily felt, walls provide an excellent route for mice to use from food to nest.

How Do Mice Get in My Home?

Rats and mice are excellent climbers, and if the texture is rough enough, they can even climb straight up a vertical surface. They can also jump 18 inches in height and fit surprisingly small gaps, making them very difficult to capture. Minor fractures in the foundation, holes in the siding, and gaps around windows and doors are all possible entry points for rodents.

How do I know if there are mice in my wall?

Mice are particularly drawn to dark, unoccupied areas of your property, including crawl vaults and wall cavities. They also tend to be well-hidden during the day, so you may have an infestation long before you ever see one. If you notice droppings, chewed wires or insulation, or hear scratching noises coming from your walls, there is a good chance that you have mice. Here are some indicators that you might be dealing with a mouse infestation:

  • Sounds of rattling or digging under the floorboards or in the walls
  • Food containers with small holes, deteriorated fabric, or cardboard boxes
  • Small, dark seeds that appear to be droppings
  • Unusual ammonia-like odors in the home
  • Nests are generally constructed of soft materials in inaccessible areas of your house, such as beneath cabinets, behind appliances, in basements, and other obscure places.
  • Feet and tail tracks on dust-covered floors
  • Check these symptoms around any area where food is kept and along with the flooring of basements, cellars, lofts, crawl spaces, and other inconspicuous areas.

Getting Rid of Mice in Walls

If you find any of these signs in your house, it is crucial to get rid of the mice as soon as possible.

Learn Their habits

Understanding the habits of mice in walls is critical to getting rid of them. They like to travel along the edge of a wall, so placing traps there is likely to be most successful. You can also place them near holes where the mice enter and exit. Mice are foraging animals, so they’ll investigate anything new, including mouse traps and bait stations. Second, they’re nibblers. Each night, on average, a single house mouse will visit up to 30 different food sources. That means you’ll have plenty of opportunities to get them where you want them with the right bait.

Third, they’re curious. Mice will check out new objects, including traps, even if they know there’s danger lurking. Finally, they like to play hide-and-seek. So don’t be surprised if your traps suddenly go missing and only reappear after you’ve added a little more excitement to their lives with some tasty bait.

Set Traps

There are several ways to get rid of mice in your walls, but the most effective way is to trap them and remove them from your home. It’s critical to employ the appropriate traps at the right time and in the correct spots. Remember, mice like to stay close to their food sources, so placing traps in the middle of your floor is a waste of time. The most common type of trap for mice are:

  • Snap Traps: There are several types of mouse traps on the market, but the most effective type is the snap trap. These traps work by luring the mouse into a small enclosure with bait and then snapping shut when the mouse takes the bait. You can buy snap traps at most hardware stores or online.
  • Electric Traps: Mousetraps with fatal electric shocks are sold to kill the rodents. They are built to prevent people and pets from being harmed by electricity.
  • Glue Traps: Glue traps are made of a sticky adhesive substance that traps the mouse when it walks on the trap. Once caught, the mouse will eventually die from dehydration or starvation.
  • Live Catch Traps: Another way to get rid of mice is to use a live trap. These traps work by trapping the mouse inside a small cage so that you can release it outdoors. Live traps are less effective than snap traps, but they are useful if you want to release the mouse somewhere other than your home.


Mice living in walls can be controlled with baits. However, poison bait can be dangerous to both pets and children, so it is essential to use this method with caution. A bait-station is not the same as a mousetrap. The rodent bites into the bait block inside, then departs, most likely returning to its nest to perish.

Call an Examinator

Mice infestations are difficult to remove, so it’s probably not a good idea to drill more than one hole before consulting a pest control professional. These businesses will know how to get the mice out of your walls without causing too much damage to your property.

How to prevent mice from entering your house?

Mice are pesky little creatures that can cause a lot of damage to your home. Mice can cause structural damage as they gnaw on wires and pipes. There are a few things you can do to prevent mice from entering your house in the first place, such as

Seal up your house

Once you’ve dealt with the infestation on the inside, be sure no more mice can get in. Mice may pass through holes as tiny as a dime. Rodents can gnaw to make an opening larger even if it doesn’t start that large. Inspect your foundation, eaves, roofline, and other possible entry points and seal them up with caulk, steel wool, or wire mesh.

Remove food sources

Don’t leave food out on the counters or in the pantry—store food in airtight containers or the refrigerator. Clean up any spills or crumbs right away and make sure there are no holes in the bottom of your trash can. Don’t leave pet-food out overnight, and make sure you’re regularly picking up any pet waste.

Keep your house clean

Mice like to live in dirty, cluttered places. Keep your house clean and organized to discourage them from making it their home. Remove clutter from your garage and basement and vacuum regularly. And seal your trash cans. You may even read our article on Things to Never Store in Your Garage to know about how to prevent mouse from entering your garage.

Prune Shrubbery away from your house

Shrubbery and branches provide a welcome path for mice and insects to enter your home. Trim shrubbery back from the outside of your property to restrict their access to the house. Mice prefer to dwell near stacks of firewood, so keep them at least 20 feet away from the building.

Mouse-proof you Yard

Take a look around the outside of your property after you’ve finished sealing the inside of your house. Mice like to nest in woodpiles, garbage bags, compost heaps, and untrimmed shrubbery because these provide excellent hiding places from predators, so move them away from the limit of your home. Maintaining a clean lawn, in general, will deter mice, as they don’t like to cross open spaces.

Breakout essential oils

According to Mannes, homemade cures are not the most effective way to get rid of mice; however, some natural deterrents may be worth a try. Some people claim that peppermint and clove oil deter mice. Soak cotton-balls in these oils and place them in locations where mice frequent, such as drawers and cabinets. Mice also don’t like the smell of citrus, so try sprinkling lemon or orange peels near their entry points. Putting a little bit of ammonia in the areas where they live is also effective.

These are some of the simplest ways to prevent mice from entering your home.
