If you’ve ever heard scratching in the walls at night or spotted mouse droppings in your pantry, you know how unsettling mice can be. They may look cute in cartoons, but real-life mice don’t sing, don’t bake cookies, and certainly don’t help with housework. In fact, mice can become a major problem — fast.
They chew through insulation and wiring, contaminate food, spread bacteria, and reproduce at an alarming rate. In other words: one mouse is never just one mouse.
This guide breaks down exactly how mice get in, how to keep them out, and what to do if they’ve already made themselves at home — so you can protect your property, your family, and your peace of mind.
Mice are resourceful creatures, and they only need an opening the size of a dime to enter your home. Common entry points include:
So why do mice move inside for the winter?
As temperatures drop in fall and winter, mice look for the same things we all want—warmth, food, and shelter. Inside your home, all three are readily available.
Here’s the catch: at the first sign of activity, you should take action. Mice reproduce rapidly, so ignoring even one sighting or a few droppings can quickly lead to a full infestation. If you know there are gaps around your garage or pipes, sealing them early can prevent a major headache later.
The best way to deal with mice? Don’t let them get inside in the first place.
A well-sealed home is your strongest defense. Key steps for sealing your home include:
Many homeowners don’t notice vulnerabilities until rodents already have. A seasonal inspection identifies issues before mice do—saving you time, money, and stress.
If you want true peace of mind, the Thomas Pest Services Complete Care Plan combines routine inspections, preventative treatments, and expert exclusion work to stop mice before they become a problem.
3. Smart Storage & Home Habits
Make your home less appealing to pests with a few simple changes:
If you missed the window for prevention and mouse sightings have occurred, removal needs to be done quickly and correctly.
Traps and baits can work—when used properly. But rodents are highly intelligent. Incorrect placement or baiting doesn’t just fail—it teaches mice to avoid those areas in the future.
Ultrasonic devices may seem appealing, but they are not a long-term solution. Mice often adjust to the noise over time, and the devices do nothing to fix the root issue – which is how they got inside in the first place.
Fighting a mouse infestation is more complex than just catching one or two rodents with cheese on a mousetrap. Our licensed professionals:
Too many homeowners only call for help after hearing scratching in the walls. By then, mice may have already:
