How to Find a Hole Where Mice Are Coming From in a House

If we go by “Tom & Jerry”, the holes house mice use are very obvious. In reality, though, things are quite different. Real mice can use very small holes. So small, you may not even expect that it would be possible.

Many house owners resort to traps and poisons to confront the issue. Actually, this is not really a solution to the cause as it won’t prevent mice from coming in. The best prevention is never to allow mice to get in the property in the first place. Of course, this is easier said than done, but a few tips can help you out.

Your first thought would be to look for big holes outside and inside the building. But you should know that mice are remarkably flexible. They can squeeze their bodies through almost any hole that is big enough to fit their head. This is possible because they don’t have collarbones.

With that in mind, suddenly you have to pay attention to tiny holes, indeed. This is why you will need to set aside a little time to do a full check of the outside and inside walls of your property.

Locating holes where mice could be entering the house

So, get a torch, some personal protective equipment and let’s start. You will have to carefully inspect the attic and basement as a start. Check and mark every hole you see, no matter how big or small it is. Pay close attention to the floor, too. Even small gaps between boards could be a potential entry for mice.

Mice usually prefer the more secluded areas where there’s little to none other activity. So, you will have to move some items and check behind them, as well. Another area which could be a “mice gateway” is the place where plumbing and electrical wires enter the building.

Next, it’s time to enter the rooms. You will have to check all rooms and look for holes in the walls or on the floor. Pay extra attention in the kitchen and the pantry. The food is the main attraction for the mice, so they will look for ways to get close to it.

This is an inspection you will have to do regularly. Mice can chew through wood, plastic and even aluminium. They can locate weak points, so a poorly fixed hole won’t keep them out for long. This is also something to take note of when you do start plugging the holes that you have found – use materials that are durable and thick enough.

You didn’t find any holes, but you know you have house mice? It’s also possible for mice to get through small gaps in the door or window frame. Another option for them is to use the ventilation system. So, make sure the protective grills on the vents are with a fine enough mesh and are not damaged.

As you can see, locating the holes and solving the issue, in general, is a bit of a challenge. In order to get lasting results, you may be better off calling professional help to eliminate house mice. Skilled experts can locate the holes much quicker and easier. Plus, they will give you additional advice to keep the mice out.

And there’s another benefit of calling professionals, too. During the inspection, they can find signs of other infestations and carry out a complete pest control procedure. This way, your property will be pest-free.
