How to get mice out of a wall

Getting mice out the wall is the same as getting them out of the attic. In fact, the mice in your walls are probably travelling up and down, maybe via wires or pipes, and actually spend most of their time in the attic. Here is how you get the mice out of your walls, in 4 steps:
  • 1 - Inspect the house and find out how the rodents are getting inside.
  • 2 - Seal up every single last entry/exit hole and gap with steel.
  • 3 - Trap, properly trap on rat runways, ALL the mice, and remove them from the house.
  • 4 - Clean up the attic space (vacuum droppings and spray Bac-Azap) or home once they are all gone for good.
  • 5 - If you need professional help from an experienced pro that I recommend, click my Hire a Pro page.


So you are tired of having little mice running around your house, kitchen, study room and even your garage, especially when you don’t seem to catch or see any of them. They always find a way to run faster than you, and you never get the chance to get rid of them. Well, you might want to change your strategy and make a stop to these unkind visitors in your home. You need to get them out of your wall!

Find out the little mouse holes dug out on your walls. We know mice don’t quite have mansions they live in. If they do, then it’s just at the darkest corner of your house, behind those big boxes of stuff you don’t use anymore. If there’s any chance mice can find a cozy spot to live in, then it must be places you forgot exist in your house. Move those boxes away, the heaps of old clothes in your closet and find those notorious spacing the mice have found most convenient to use to hide away from you. Clear out your house to clear out your rodents.

Once you find the mouse holes, it’s time to activate strategy 101. Strategically place mouse traps right at those spaces. If at all mice will be running around your house, they’ll do it at night when it’s dark, or the moment you’ll turn on your kitchen lights for a midnight snack from your fridge. Place mouse traps at the openings of these spacings, to trap these rodents when on their “homeruns” away from you. Ensure the trap is placed right at the opening to avoid them missing the trap and dodging their death beds. We wouldn’t want generations of mice breeding between your walls. Get the traps and kill the mice.

Lastly, we are trying to get these mice out of your walls so you would definitely not want to get too smart to use poisoned cheese slices on the traps. Mouse poison, like any other poison, would take twenty minutes or more, before it finally kills its host. So if you use mouse poison, chances are the mouse would maybe get away with the cheese slices, and probably take it to the rest of “the clan” for a feast. So one day later, you’ll have a whole bunch of dead mice stuck in your wall, which would definitely piss off your home dinner date. She can’t stand a foul smell of rotting corpses. Do not, by any chance, use mouse poison. You do not want to face the consequences! Mice in the walls can be such a great distress. It just takes a simple smart mind to take them down.

Mice prefer to live in dark hidden areas throughout your home. This can be storage boxes, attics, unused furniture, and between your walls. Mice can fit through tiny cracks and fissures in your walls, floors, and foundation. Once they move in they seen impossible to get rid of. Mice rarely leave their resting place during the daylight hours. They are nocturnal and prefer to move gnawing and clawing at night. A mouse infestation can be a very serious problem for any homeowner. They are destructive with their constant chewing, and can spread filth and diseases. First make sure your infestation is actually mice. While Visual confirmation is a sure fire way, there are other signs as well. Another sign is scratching, chattering, and squeaking noises in the walls. You can also look for droppings in concentrated areas especially in areas with food and water. If you do have a problem with mice, getting rid of them won’t be easy.



Start by identifying their entry spots. These can be from the inside, or outside. Broken siding, chimney stacks, and vents stacks can also allow access. You are able to identify mice entry ways from the dark oily markings that they leave behind, as well as the rice shaped droppings. Once you have identified their mouse doors, you can watch for activity. Mice will exit sometime around dark in search of food and water. How you decide to proceed determines when you will seal the opening. If you decide to simply dump poison pellets in the walls and allow it to take care of the problem, leave at least one hole for the sick mice to leave. Watch for dead or dying mice so other animals don’t eat them. This method may present a problem if the mice have nests of babies, who do NOT ingest the poison, or the dying mice don’t make it out, and then you will have dead bodies in your walls! If you decide to trap them, leave one opening and use a trap baited with food to lure them out.

If you decide to trap them are you going to use kill traps or live traps? Either one leaves you with a mice to deal with. You just must determine whether you wish them to be alive or dead. Often the best course of action is to call a professional service that can take care of the job for you. Once you have confirmed you are mouse free, seal all openings that you have found even if they don’t show signs of being used by mice. You can further deter rodents and other creatures by applying an irritant like a layer of fiberglass insulation near these areas. The fiberglass is extremely bothersome to many animals delicate skin. Once the remaining mice realize they cannot return to their nests, they will find another place to call home. To avoid future invasions by mice and other rodents, routinely inspect and maintain the exterior of your home. Prevention is always better than having to affect a cure!
