Mice might leave if their primary food source is completely gone, but they often won't leave a home just for that reason, as they also seek shelter, warmth, and water, and can survive for a while on minimal food or alternative sources like paper or seeds. Simply removing food isn't enough to get rid of an established infestation; you need to also seal entry points and eliminate water/shelter to make your property truly unattractive.
Mice need a place to nest and nearby food in order to survive and multiply. In a context where you abruptly remove the food, the environment would suddenly not be able to sustain such a large number of mice; therefore, mice would look for more favourable environments and many, if not all, would leave.
Mice often enter peoples' homes to improve their chance of survival, whether that involves finding warmth, food or both. As long as a mouse finds what it needs within your space, it is unlikely to leave of its own accord.
Even with their strong survival instincts and knack for finding tiny bits to nibble on, mice can only survive without food for quite a few days. On average, they might go without food for around 2-4 days.
Mice have a very strong sense of smell and are often repelled by very strong odors like cinnamon, vinegar, dryer sheets, clove oil, peppermint, tea bags, and cayenne pepper. I decided to try diluting peppermint oil in a spray bottle and misting it around my feed room and tack room.
The good news is that with proper pest control and prevention, you can indeed ensure all mice are completely out of your home. If you suspect a mouse infestation or have questions about how you can be sure to completely get rid of mice in your home, seek help from a licensed pest control professional immediately.

While mice need food to survive, they are resourceful and can live off a wide range of materials, making them difficult to deter simply by removing food sources. Keeping your home clean, sealing entry points, and eliminating potential nesting spots are all vital steps in making your home less appealing to mice.
The sounds you hear are often signs of mice foraging, nesting, or expanding their territory within your home's structure. Understanding why mice scratching walls in January is so common helps you take the right preventive steps, sealing entry points, removing attractants, and scheduling professional inspections.
For the most part, mice want to avoid you as much as possible, but if your sleeping body is between a mouse and a morsel of food, the mouse may take the shortest route between to point and crawl over you.
The Reality About “Just One” Mouse
You might think that spotting one mouse means you only have one mouse. This rarely happens. Mice live in family groups and reproduce quickly. If you see one mouse during the day, it usually means the hidden population has grown large enough that they're competing for food and space.
Peppermint Oil One of the most well-known mice repellents is also the most effective. Just a few drops of peppermint oil on a cotton ball will drive away rodents. Remember to replace the balls every few days to keep the scent strong - and don't let your pet near them.
Like droppings, mice also tend to leave foul smells from their urine. A good way to tell if mice no long roam in your home is if the foul, Ammonia-like smell diminishes. You can't smell this odor if mice no longer relive themselves in your home.
Here are some signs of a bad mouse infestation to be on the lookout for throughout your house, including the attic:
To get rid of mice fast, combine immediate trapping with long-term prevention by sealing entry points (using steel wool/mesh), eliminating food sources (cleanliness, sealed containers), and using deterrents like peppermint oil or cayenne near trails; snap traps with peanut butter are effective, but for severe infestations, professional pest control is best.
In the spring and summer when temperatures are warm, mice are very active and will breed and expand their population outdoors. Mice have low cold tolerances, so when temperatures get colder in the fall and early winter months, they'll look for warmer shelter and reliable food sources to survive.
Most of the time, we can handle it from the outside—set traps in attics, crawlspaces, drop ceilings, or under cabinets. Mice don't stay deep inside walls all day. They come out for food and water. That's when we get them.
Look for signs of rat or mouse infestation: Rodent droppings around food packages, in drawers or cupboards, and under the sink. Nesting material such as shredded paper, fabric, or dried plant matter. Signs of chewing on food packaging.
The first step in finding the source of the scratching sound is to determine whether it's caused by an animal or some part of your house that has come loose. If the sound is regular and predictable, it's probably not made by an animal. Look for a piece of siding or gutter that has come loose in the wind.
The answer is yes—mice are primarily nocturnal creatures, meaning they're most active when the lights go out. If you've been hearing those unsettling noises in the walls or finding tiny droppings in your kitchen, you're probably dealing with nocturnal visitors.
Mice multiply quickly, chew through insulation and wiring (posing fire risks), and carry dangerous diseases. Ignoring the problem can lead to major property damage and health hazards. Prevention and fast action are key.
Gnaw Marks: On food packaging, wood, or wiring. Odor: A strong, musky ammonia-like smell from mouse urine. Scattered Materials: Bits of shredded paper or fabric that didn't make it into the nest. Noise: Scratching or scurrying sounds, especially at night, may point to active nesting areas.
How to get rid of mice in your house
Cinnamon – The strong, spicy scent of cinnamon can overwhelm a rodent's strong sense of smell. Cloves – The intense, spicy fragrance of cloves can be irritating to pests and drive them away from treated areas. Eucalyptus oil – The menthol-like aroma of eucalyptus can be too strong for these little critters to tolerate.
