Table of Contents

Having mice in your home can feel like a monstrous problem. Mice can hide in basements, attics, storage, and even walls. When the worst has happened and you discover mice in the walls, Hama Pest Control has you covered.

So, how do you get rid of mice in the walls? Here’s a glance at the steps you can take:

  1. Learn their habits
  2. Set traps and baits
  3. Place and reposition traps and bait stations
  4. Call an exterminator

These steps are certainly helpful, but it’s best to prepare yourself for this situation by learning more about how to get rid of mice in the walls.

How Do Mice Get in My Home?

If you have mice in your home, you’re probably wondering how they got there in the first place. After all, if you never solve this initial problem, you will only continue to deal with mice in the future.

Cracks in the Foundation

A small crack in your home’s foundation may not seem like much to you, but to a miniature animal like a mouse, it’s an open invitation to enter your home.

If your home has rubble or a stacked stone foundation, you’re even more likely to experience cracks and gaps.

Attics

Many attics, especially older ones, feature small holes for things like fans and electrical wiring. It’s not hard for a teeny, tiny mouse to squeeze through these openings.

And because attics are typically used for nothing more than storage, you may not notice these gaps as quickly as you would elsewhere.

Basements/Crawl Spaces

Unfinished basements and crawl spaces are ideal entrance points for mice. These areas are dark, hidden, and unfrequented, making them ideal homes.

Many crawl spaces also have little holes and cracks where mice can come and go as they please. These locations are perfect, as they give the animals access to both your home and the outside.

Gaps in Doors and Windows

Older homes are more likely to have the issue of gaps in doors and windows, as aging and warping play a significant role. In severe instances, it is typically worthwhile to replace the whole frame. Other times, solutions like steel wool, sealants, or caulk may help.

Can Mice Climb Walls?

Can mice climb walls? The answer here is mostly yes, but sometimes no. Whether or not a mouse can climb a wall depends entirely on the material with which the wall was built.

Mice can climb any wall with an uneven, rough, or porous surface. They can also climb walls that feature some kind of additional footholds for them to grab onto.

They can also easily climb the inside of a wall because it’s filled with supporting beams, wires, insulation, pipes, and more.

How Do I Know If There Are Mice in My Walls?

Several signs can help indicate you have a mouse problem in your home’s walls.

Noises

One of the most noticeable signs of mice in your walls is the sound. Mice are typically most active during the night, so you’re more likely to hear these noises during the evening and throughout the night.

If you hear rustling and scratching coming from your walls and floorboards, there’s a good chance you have some kind of rodent infestation.

Droppings & Smells

Not only will you find droppings in your home during a mouse infestation, but you will also notice an unusual smell.

That smell is from mouse urine, which will emit an ammonia-like odor. To get rid of this horrible odor, certain steps must be followed when cleaning up mouse urine

If you’re spotting small, dark pellets about the size of seeds and noticing this distinct smell, you likely have mice in your walls.

Runs

Mice are creatures of habit, so they tend to run the same path from one place to another – for example, running from their nest to their food source.

Over time, the constant running paired with their claws and the oils these creatures carry eventually cause these paths to become visible along wooden pathways, countertops, and drywall.

How to Get Rid of Mice in Walls

There are plenty of tips and tricks we could give you to solve a mouse problem, and a step-by-step solution can do the trick. However, to ensure that the problem has been completely eliminated, pest control services are the best option.

Learn their Habits

There are a few key things you need to keep in mind about mice:

  1. They’re always looking for food
  2. They visit food sources up to 30 times per night
  3. They don’t travel far for food

These three main habits of mice are critical to catching them and removing them from your home for good. The fact that they are constantly scavenging is good news for you. Any traps you place will likely attract them.

Likewise, knowing they’ll visit a food source several times a night gives you the upper hand.

And thirdly, once you find a mouse’s hiding spot, you automatically know how far it’ll travel. This knowledge can help you with step number two: setting traps and baits.

Set Traps and Baits

There are several different types of traps and baits, including:

  • Humane mouse traps
  • Snap traps
  • Sticky traps
  • Poison
  • Electric traps
  • Ultrasonic devices

The type of traps and baits you choose to use will depend on your personal preferences. Some folks don’t love the idea of killing the mice. If that sounds like you, then humane mouse traps and ultrasonic devices are in your wheelhouse.

Many people don’t have a problem with snap traps or electric traps because they kill mice quickly and painlessly. However, sticky traps are often considered cruel because they trap a live mouse until it dies slowly of starvation.

Finally, poison allows mice to run away and crawl back into the walls before they die, making it difficult for you to find and dispose of them.

Place and Reposition Traps & Bait Stations

When placing your traps and bait stations, it’s always a good idea to place several in different locations. Because you defined your mouse’s habits in step one, it should be easy to determine the best places for your traps.

If you haven’t caught any mice in three days, reposition them to other locations. Try changing up the bait, too.

Call an Exterminator

When all else fails, consulting our professional team at Hama Pest Control is your best bet. No amount of internet research can measure up to the years of training and experience that professional exterminators can offer.

Dead Mice in Walls

So, you’ve located the mouse problem, set your traps, and now you haven’t seen or heard any mice for a few days. But you notice an unpleasant smell. This smell usually indicates dead mice in your walls.

Find dead mice in your walls by using a borescope to drill tiny holes. Once you locate a dead critter, drill a slightly larger hole and remove them.

Mice pest control isn’t fun, but it’s sometimes necessary. Protect your home from these rodents by following the guidance we’ve provided, and be sure to call Hama Pest Control when you run into rodent problems.
