Signs You Have Mice in Your Walls

Mice infestation can go on for months unnoticed since these rodents tend to stick to unoccupied, dark areas in your home like air ducts, wall cavities, attics, and crawl spaces.

Furthermore, they are nocturnal, thus active in the daytime.

The tell-tale signs of mice infestation in your house walls include:

1.  Mice Droppings

You likely have a mouse infestation if you see droppings that resemble tiny dark seeds in places these rodents may have traveled, including under appliances, attics, and cabinets.

Older droppings are faded and dried, while new ones are black and shiny. Aside from feces, you may also find mouse urine.

2. Runs

Mice will repeatedly use the same route from one place to another, and runs will be left in these areas after a while.

While they are not easily noticeable, pay attention to faint runs along chewed fruit buckets, pierced bread bags, and other regions.

3. Nests

Mice will use different materials within your home, including cardboard boxes and clothing fabrics, to create their nests.

Mice nests are usually found in dark areas such as storage boxes, under furniture, closets, and cabinets.

Mice droppings and nests are typically found in close proximity.

Other signs of mice infestation include:

  • Scratching or rustling sounds coming from under your floorboards and walls
  • Tail or feet tracks on your dusty floors
  • Tiny holes in your old fabrics, cardboard boxes, or food containers
  • Unique ammonia-like smells.
  • Gnawed or chewed drywall or wood.
  • Destroyed insulation.
  • Fur in a home without pets.

Best Ways To Get Rid Of Mice In Walls

Mice are hard to eliminate, especially since they multiply pretty fast. However, you can use some methods to create a mouse-free environment at home. Below are the ways of removing mice from your walls and home.

1. Remove Things That Attract Mice

There are plenty of food sources for mice around your home. These tiny rodents consume nearly everything because they are opportunistic feeders.

When outdoors, mice consume compost, birds and dead animal carcasses, insects, trash, vegetables, seeds, and fruits.

Once they enter your house, they will eat various kinds of food they can access, including cereals, meat, cheese, bread, crumbs, and pet food.

To avoid attracting mice to your house and walls, make your home unattractive by removing food debris.

Water can also attract mice, so pay attention to sources of water like water dishes, leaking or damaged pipes, a leaky irrigation or garden hose, and water fixtures in your yard.

 2. Use Mice repellents

Peppermint oil is a popular mice repellent that can be sprayed or dabbed onto cotton balls and placed near the mice’s entry points or where they are nesting.

Other natural mouse repellents include cedarwood oil, cloves, and cayenne pepper.

3. Seal Entryways

Keep mice out of your walls by sealing holes and cracks around your home’s exterior to block them from getting inside.

Before closing the entryways, inspect the attic vents and crawlspaces for any destructions caused by mice.

Spray foam is usually used to seal gaps and cracks, but the downside is mice will chew through it. So, consider using wire mesh or steel wool.

4. Get Rid of Nesting Points

Mice can use vegetation in your home or yard debris to develop their nests. These areas include wood piles, hollowed stumps, leaf piles, rocks, and dense bushes.

Mice can also use vegetation to enter the house.

For instance, they can use the branches of overgrown plants to gain access inside your home and make way to the walls.

5. Set Traps

Before placing traps on different areas of your house, you must be absolutely sure mice have created a home in your walls.

This is particularly essential, especially for a household with pets and small kids at home, since the traps can hurt them.

The common mice trap types are:

a) Snap Traps

These are the conventional and most common trap types. Snap Traps  are highly effective, affordable, and easy to set up. All you need to do is to bait the cup or plate and pull back the lever, which will then be released and snap closed when the mouse takes the bait.

The mice die with this method, and you can hurt yourself while using it.

b) Glue Traps

Glue traps are also cost-effective and work by trapping the mice on their sticky surface. While they are safer for kids, pets, and adults, glue traps are inhumane, and the mouse can get away.

c) Catch and Release Traps

If you do not want to kill the mice, catch and release trap is the best option since it involves trapping and releasing the rodents. They are also reusable, but you must monitor them regularly and transport the captured mice. Also, they are pricier.

d) Electric Mouse Traps

Electric mice traps kill mice quickly, are highly effective, and prevent too much suffering. They are ideal for indoor use and cost more.


Being proactive is the best way of keeping your home mice-free. So, start by maintaining a tidy home and yard. However, if mice have already made their way to your house, invest in a mouse trap of your choosing.

Alternatively, hire a pest control company if the mice population in your walls is too large or you do not want to deal with the mice yourself.
