Winter and fall are the two most common seasons to see mice however, it could happen at any time of the year! Bad news, right?
Mice can and will get into your home with ease. There will likely be many mouse entry points around your house that they will take full advantage of. Mice are also opportunistic creatures and can wait for a time when you will leave your door or windows open. As soon as they get the chance, they will enter.
The list of factors that make your home susceptible to mice is endless. I will give you the top 7 reasons you have mice in your home.
Why Do I Have Mice In My House? 7 Reasons Why
Easy To Access
This is the most common reason. While poor sanitation is a reason (see below) that mice are attracted to your home, they are also more than happy to set up a home in a clean house, as long as they can get access!
You ask for trouble if you ignore or do not know what entry points are available to mice.
I regularly inspect my property to ensure I have covered every entry point I can see. That way, I can be confident that it is a challenge to get into my home!
Poor sanitation is a possible reason why you have mice in your home.
Also, poor sanitation makes it easier for mice to access food and water sources, encouraging them to make your home their haven.
Mice are scavengers, meaning any poorly disposed of garbage provides easy access to food for the mice.
The clutter also provides the mice’s materials to make a nest for their young ones. Many open water sources, such as a water bowl for your pet, also provide enough water to keep them around.
Mice are always looking for a shelter to hold a nesting site for their young ones. The fallen leaves near your house can be the right nesting place for mice and your home, the food source.
A mice nest near your house gives the mice easy access to your home through small spaces and gaps in windows, plumbing lines, ceilings, gas lines, and sewer lines. The mice could do all these just for adventure but will continue returning if they find access to food inside the house.
The mice you spot inside your house may not be living inside the house. They may be living in a nearby shelter. The shelter can be an old car parked near the house, piles of firewood, or discarded furniture.
Mice feel safer in an environment with minimal external threats and choose an area you rarely visit. Mice will then find easy access to your home from the shelter whenever they need food or water.
The natural habitat for mice is bushes and forests, but such spaces shrink in size every year. Every time an open space is developed, the mice living there must find a new home, and another similar environment can be far away.
The noise (noise scares mice) and activities at a construction site also chase the mice away, and they end up in the nearby neighborhood.
Your house could be the quiet environment they need, especially if you are rarely home.
Another factor that may force mice into your home is predators. For example, a predator near your house could be why there is a mice infestation in your home. They are running scared!
Mice are prey to various predators such as snakes, some birds, cats, and many more. Such a predator near the mice’s shelter forces them to find a safer environment, which is your house. The mice can relocate and build a nest inside your home, especially if the predator is bigger and cannot find a way inside the house.
You can always introduce a cat to your home. Mice hate cats!
Harsh Outdoors Environment
There are times when the outdoor environment is unfavorable for the mice. For example, the weather outside could be extremely hot or cold, and mice will have to find a better place for the time being.
The most notorious seasons for mice infestation is during the cold seasons of winter and fall. Mice find refuge in homes.
Unfortunately, the mice could see the environment as favorable for survival, meaning they will stay even when the climate outside gets back to normal temperature. Therefore, you must always be aware of mouse-related sounds in your attic and home.
High Mice Population in Your Neighbourhood
Another answer to the question, “why do I have mice in my house?” could be a high population of mice in your local neighborhood. A high mouse population means that they have to compete for food and shelter. The outdoor environment may not offer enough for all of them.
Mice will find alternative shelter in homes where food is accessible, and the competition is minimal. These areas are known for massive mice infestations due to the favorable environment. There is a higher possibility of mice infestation if your home is in that area.
Frequently Asked Questions
What attracts mice to your house?
Mice are attracted to many things in your home, but the most attractive things are those that offer protection from predators, warmth, comfort, and food. So instead of looking at each element, you should consider what a mouse wants and remove it!
Does one mouse mean I have an infestation?
Just seeing one mouse doesn’t mean dealing with an infestation. However, it should be a warning about a possible future infestation. For example, if one mouse got into your home, others may also get into your home!
Do mice leave on their own?
If there is nothing in your home for a mouse, they will leave on their own. This is especially true if you have a cat! For example, a cat is a natural predator of mice. A mouse will rarely leave your home alone simply because they see it as a good base for its nest!
