How Long Does It Take A Mouse To Chew Through A Wall?

If you live on the ground floor or even on the second floor, you will come across a mouse in your home at least once in your lifetime.

It is not because your house is messy or dirty, but mice will always find a way to get inside the houses and build a living area for them.

You will usually find them inside the walls or in cramped-up areas such as within boxes, behind wardrobes, or under the bed. However, you might be wondering how long it takes a mouse to chew through a wall, and this article will provide you with the answers.

How Long Does It Take A Mouse To Chew Through A Wall?

how long does it take a mouse to chew through a wall

It takes much longer for mice to chew through a wall than it is for rats. It takes about 2 to 3 days of on-and-off chewing for the mouse to chew through a wall.

Certain factors contribute to the duration for a mouse to make a hole in the wall. Such as,

  • If the mouse has access to food and water, if it is hungry, the animal will get tired quickly and finish the process faster.
  • The material of the wall plays a significant role in the speed of a mouse chewing through it thoroughly; the heavier the wall, the longer it will take.
  • The mouse has the habit of gnawing on things to maintain the sharpness of their teeth so that it will delay the hole.
  • Sometimes, they chew on stuff just to chew, and those times will also be slow for chewing through the wall.
  • If there is more than one mouse chewing through the walls.

Even after all these, the most important factor is the material of the wall. Here is a list of all materials on the wall and how they affect the chewing process of a mouse.


To anyone’s surprise, mice can actually nibble through concrete, but only if the concrete is not cured correctly or non-cured. If the concrete has more water than cement, the mouse can get through it.

The mouse might not be able to make a hole in the concrete walls, but it can squeeze within the wall or form small openings. But cured or half-cured concrete is weak enough for mice to gnaw through it.

Glass Fibre

Glass fibre is a plastic material or FRP, which is known for the mouse to be able to chew through it. These wall panels or wall coverings are not strong enough to withstand the sharpness of a mouse’s teeth.

Moreover, rodents prefer fibreglass because it provides comfort and heat and protects them from predators. Mice use these walls to build a nest and live in them.

Within the fibreglass, you will not be able to hear a mouse moving through, making this a perfect place for the entire mouse family to live in. That is why it is important to check your glass fibre walls now, so there is no mouse infestation.


Layers of fibreglass and paper, known as gypsum plaster, make up the panel’s drywall. This proves that drywall is weak and can be easily gnawed through by mice.

In this case, it will take a mouse only a short time to chew through a wall.

Drywall is very soft and edible for rodents, so they will not have trouble eating the pieces. It is comparatively easy for mice to destroy the crumbly core of these walls just by nibbling on them.


A wooden wall is effortless for pests to pick their way through. But the thickness of the wood also plays a role; if it is thick, then the mouse will have a hard time chewing through it. Even still, mice can pick their way through hardwood, but that will take longer.

The wood pieces and shavings are suitable components for mice’s nests. So not only will they get their way through it but also find items which would make up their nest. This means mice are more drawn to wooden walls than any other.


Just like wood, plywood is a feast for mice. It is slimmer and smaller, so mice can easily chew on it. Some plywood is made using soft materials, which can get soggy fast. Those are very easy for a mouse to chew through the plywood walls.

Plywood shavings are also used for the mouse’s nest, which makes such walls an easy target for these persistent pests.

How To Prevent Mice From Chewing Through A Wall?

  • Set up mouse traps in your home to catch these pests; set them up in areas where it is easy to find the trapped mouse.
  • Consult any pest control professionals to control the growth of these rodent pests in your house.
  • Keep your house clean, and tidy and less stuff so that mice do not find ways to build a nest.
  • Wildlife troopers will find a way of getting the mouse inside a wall without damaging your house heavily.
  • Secure any entry points for the mice so that new mouse infestation does not occur now and then.

Even after taking all the precautions, you are bound to find mice in your home, do not fall into despair.
