How to Get Rid of Mice: The Complete Guide

To some point in your life, the chances of encountering a rodent infestation is culpable. Rodents are procreating at a rapid rate and this leads to many areas of the world being infested by mice. However, the right knowledge will allow you to get rid of these mice and continue with a life that does not include rodent infestations.

I have struggled with mice and rats for a time now and have learned some of the techniques and tips, has helped a lot of with ridding the home or building of them. In this guide, we explore some of the signs or rodent infestations, while also guiding you with the right tips that can rid your building of rodents and other infestations.

Signs of Mice Infestations

Before it is possible to get rid of the mice, the infestation needs to be detected. There are a couple of signs inside and outside a building that could give away the presence of mice. Fortunately, these are quite common and universal, making it easy to detect them once you know how.

Here is what you need to look for if you think you have a rodent infestation:

Signs of Rodent Infestation inside the Building

  • Droppings: One of the first signs is the droppings of the rodents. Depending on the rodents, these can be small droppings, while gradually becoming larger depending on the species. The droppings are commonly found around food sources.
  • Urine Odors: Urine odors of mice won’t have the same foul smell that we expect from pets like cats. They are subtle, but as the infestation grows, these urine odors will become more prominent.
  • Holes: Mouse holes are not as clean as you would expect them to be. The movies give us a false sense of how clean mice are. You can find small holes around your walls or in wooden furniture with small marks for the rodents to fit through
  • Rub and Gnawed Marks: Once pets have been eliminated, one can easily seem small gnaw marks around the area. Shredded papers and other materials that mice can use as shelter are a common sign that an infestation is around.
  • Rodent Runways: On most slippery or solid surfaces, one can detect these small strips of space that rodents choose to use when they are moving about. These will generally be more prominent as the rodent infestation grows.
  • Rodent Nests: Chances are that you won’t commonly find the nest without a little searching. However, you might find some signs of a nest, including sound through your walls or within your furniture.
  • Scampering Noises: Rodents are not the quietest of animals and while they try to be, you will eventually hear them scampering around if the infestation is left unchecked. However, you need great hearing about this.
  • Pet Behavior: Different pets will behave differently when you have an infestation. Cats are some of the best animals to monitor and they tend to be around the same location often. This allows them to catch the mice if possible.
  • Seeing a Mouse: Finally, you can potentially see a mouse around the home. This can either be a dead mouse or one that is alive. Once you notice the first mouse, it is important to do some investigation.

Signs Of Rodent Infestation Outside The Building

  • Gnaw Marks On Garden Furniture: Most rodents don’t like being outdoors, but if they have a nest outdoors, you might find some of your furniture full of holes or other gnaw marks, especially if the furniture is hardly ever used.
  • Droppings: It can be hard to spot at first, but when it is not cleaned, the droppings can be more prominent. This is generally found on a patio or on solid surfaces that the mice use to move around.
  • Holes: Mice will commonly try to find the shortest path to their food sources and this means they will try to get inside your house. You might find small holes on the outside of the building leading in.
  • Odors Form Unused Areas: Homes vary from design to style and this leaves many large homes with hidden areas that are never used. Since the mice will like these areas, they are commonly found to leave urine and dropping odors.

How Do Mice Get In Your Property?

Mice are generally small and this makes it possible for them to squeeze through small hole and cracks. These cracks can allow the mouse to easily get inside your home without too much effort. There are a couple of ways or weaknesses in your home that the mice will exploit if they want to enter.

Here is a small breakdown of these weaknesses:

Cracks (Wall or Ceiling)

Cracks in your walls or your ceiling can be used to burrow through by the mice. Since this is small weakness in the structure, it won’t take the rodents as long to gnaw through and eventually find their way inside a building.

Open Windows

Believe it or not, but mice are nifty little creatures and while gravity prevents them from climbing wall, nothing is stopping them from entering through windows. Occasionally, you might need to check areas that have constant open windows.

Drain Pipes

Drain pipes are not always sealed and covered to keep all the rodents out. This means that if the drain pipes are unused for a while, the rodents might find their way inside the building. If the pipes have leaks, they can expose this weakness by climbing through these small cracks or holes.

How To Get Rid Of Mice In Different Locations

If you have finally uncovered mice in your home, you need to take some steps to get rid of them. This can vary from location to location, but most of the principles will still remain the same. Here is my guide of getting rid of mice based on the location that you have found them in:


One of the first places that mice tend to choose for an infestation in the basement. The basement is not used as often as other areas of the home and this allows them to roam around freely. They will remain in this area until the food is eventually removed. Mice commonly enter the basement through windows and open doors, but structural weaknesses and cracks also allow them to get in. Here is how you can get rid of them:

  • Traps: The common option is by setting up traps. This is one of the preferred methods and while it might not kill the mice. It will trap them and you can dispose of them on your own peril.
  • Natural Remedies: If you are an environmentalist or you have spotted the traps fast, you might consider natural remedies to get rid of them. These include sealing up specific areas and also removing the food or water sources. I do recommend still keeping track of them to ensure they don’t spread to other areas in the home.
  • Commercial Repellent: A wide variety of commercial rodent repellents like the ultrasonic repellers are available. This is another humane way to rid yourself of the infestation and get the mice away.
  • Poisons: Poisons should only be considered for large uncontrollable infestations and when you don’t have any pets around. This can rid your building of mice quite fast, but can also be dangerous for pets.
  • Exterminator: If none of the above-mentioned have worked for you, you might need to consider calling an expert that will assist you with the infestation problem. These trained professional can get rodents out in no time at all.


The walls in your home can be hardest to exterminate when you have detected an infestation. Mice like to make holes in the walls and they tend to live inside these walls. Aside from breaking down the walls to get them out, you are only left with a few options that will actually work. Here is what I have done to get rid of mice:

  • Poison: One of the best ways to get rid of an infestation in a wall is to put some poison inside the wall. However, this might leave you with dead mice inside the wall and it can leave a bad odor. It might also drive them out if you are lucky.
  • Traps: Traps remain the best way to get them to come out of their nests. This can help you avoid having dead mice left inside your walls.
  • Sealing The Holes: If you don’t feel like doing anything that will harm them, you might have some luck with sealing up the wall. This works even better when you use a poisonous liquid sealer to do the job.


The next most common spot to find mice is in the kitchen. The kitchen can be a daunting area to keep clean and this needs to be done daily. Since there are many food and water sources for the mice, the love the kitchen, but here is how you can get of a mice infestation:

  • Traps: There are a variety of different traps that you can use for your mice. These traps can electrify or simply catch them. However, you need to set it up carefully near the infestation site to make it more appealing. Having bait with a little bit of an odor might encourage them even more.
  • Natural Remedies: If the infestation is still small, you might be able to get rid of it by simply spraying some peppermint oil. Sealing up some of the holes will also be helpful to keep them at bay.
  • Commercial Repellent: This is pretty much self-explanatory and you can use them much as you will in your basement to get rid of mice.
  • Poison: Poison is an option, but not recommended in areas that you have food. If you can clean out the kitchen for a while, you might be able to use poisons. However, the kitchen needs to be sanitized afterward.
  • Exterminator: An exterminator can help to detect the mice and they have safe ways that will get rid of the infestation. This is one of the first options that I would recommend for kitchen infestations.
  • Ultrasonic Pest Repellents: The ultrasonic pest repellents are still being disputed, but they can make a massive difference. You might need to ensure that the pest repellent you choose is actually approved by the right bodies.

Attic, Ceiling, And Vents

Mice tend to prefer the attic or even your ceiling due to the inactivity of people not using these areas. While they can spread quite rapidly, you might need to set up a couple of traps or even scout around for entry points to keep them out. Sealing of the entry levels are the best way to keep them from spreading, but you can find some more creative ways to get rid of them as well.


Much like the attic and the ceilings, your garage is a warm spot for the mice to invade in the fall. This spot is generally cluttered and we don’t really look too much at the infestations. Mouse poisons can work wonders here and with a little bit of decluttering or cleaning, you can rid your garage of the infestation. There are many more ways you can use to get mice out of your garage.


If your garage is infested, there are chances that your cars will also become a target. Mice can easily get into vehicles that are not maintained or used on a regular basis. To avoid this, you need to check the car often for signs of infestations, but keep the mice away from the car in the first place. If you have an infestation, you can use a variety of ways to exterminate them on your own.


The apartment is the place you stay and live and when mice invade, it can be hard to get rid of them on your own. While you have a couple of ways to get rid of them, you should consider calling your property owner and discuss it with them. They are bound by a contract that will obligate them to get rid of the infestation for you.

Different Methods to Get Rid of Mice

Mouse Traps

Nothing is more daunting than having a few mouse traps set up around your building. Mouse traps are effective and they have been used for many years. Modern technology has allowed us to even electrify the mousetraps to allow them to be more potent. You can find a variety of great mousetraps that will get the job done.
