How does the mouse react in winter?

As you know, mice don’t hibernate in the winter. On the other hand, outdoor and unheated places are not comfortable for them; These rodents like warm, dark and calm places to set up their nests and consume the food that would ideally be nearby.

Why do mouse infestations increase in winter?

Mice in winter become more intelligent, because it is a question of survival for them: the freezing climate and the rare food are warning signs for all species. This is why we observe a clear increase in invasions by mice during this difficult season. Thanks to their small size, they will enter your home through holes you don’t even notice!

Once installed, there will be signs that will make you understand their presence: tiny noises, a bad smell in the corners, bite marks in your remains or other (because mice are omnivores), and also their droppings.

If you’re thinking of keeping mice in your home over the winter because you think they’re cute, we strongly advise against it. Indeed, they are reservoirs of germs, they damage your objects, they risk attacking you and they make your house very dirty. So don’t let any mice into your home this winter!

Our tips to protect your home from mice this winter:

The first thing to mouse control is simple prevention. It sounds logical (and it is), but it’s not always easy! The situation can quickly become unmanageable without effective tips from experts. Here is our selection of essential measures to take to keep mice away in winter:

1. A major cleaning of the interior

It is really this first step that is fundamental to avoid invasion by mice this winter. The idea is to make your home unfriendly to pests whose preferences you now know.

Store your belongings meticulously and get rid of anything that is no longer useful to you. Free up maximum space by removing dusty corners. Don’t forget to clean the floor thoroughly to remove food crumbs. You can also wipe your furniture. Emphasize the kitchen, the attic, the cellar and the garage a lot!

2. Home maintenance

Eliminating entrance doors is absolutely imperative because a house that is not comfortable for mice does not prevent them from trying to enter anyway! They must therefore be discouraged by placing obstacles where they enter from.

Caulk the holes in doors and windows which are easy to make and then patch the voids in the structure of your home.

Also think about closing the bottoms of the doors through which a small mouse can enter!

Repair well the contours of your pipes and drains because they form a major entry point for rats coming from the sewers.

Place wire mesh to cover the fan outlets.

By eliminating possible entrance doors, your inaccessible home quickly discourages mice come winter.

To protect your house from mice during winter, it is smart to make sure that these pests do not even approach the periphery.

First, you should clean up any standing water near your house. Next, try cutting tree branches that are close to your structure, as mice can use them to get in through the window! Don’t forget to remove weeds from your garden, end up clearing the space of everything including pet food.
