Yes, it can be normal to have recurring mouse issues yearly, especially in older homes or rural areas, because they seek warmth in winter and reproduce rapidly, but it's a sign of an ongoing infestation if they keep coming back; you need to seal entry points and remove food/water sources to truly stop them. A single mouse is rarely the whole problem, as one female can produce dozens of offspring yearly, quickly repopulating if conditions remain favorable.
Reasons Mice Enter Homes
One primary reason for this invasion is the presence of readily accessible food sources. Homes that have food waste, spills, or unclean environments are especially inviting to mice, as these areas provide many opportunities for easy meals.
They're widely distributed across the whole country and prefer to live in close proximity to human habitations where food and shelter are easy to find. Even if you've never seen a house mouse there's a chance you're living closer to one or several of these small rodents than you might feel comfortable with.
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.
Mice are generally wary of humans and prefer to avoid direct contact. However, they may explore the sleeping area if they perceive a food source nearby. To prevent this, ensure your bedroom is free of food remnants, and take steps to seal entry points. If needed, consider using traps as a proactive measure.
When you hear scratching, it's usually mice busily navigating the hidden parts of your house, searching for nesting materials or food. These sounds are most often heard during the quiet of the night, when mice are most active and when your house is at its quietest.
House mice fall prey to owls, hawks, cats, dogs, skunks and snakes. Barn owls are particularly efficient mice predators. A single family of these owls can consume more than a dozen mice in one night. House mice usually live only one year in the wild due to predators and exposure to unfriendly environments.

Beyond health concerns, mice can also damage insulation, wiring and stored belongings, creating fire hazards and costly repairs. Their rapid reproduction means a small problem can quickly turn into an infestation, making prompt prevention and cleanup essential for a healthy, safe home.
Australia's Top Pests!
There are a number of different things which might attract mice into your home, including: Small pieces of food and crumbs which haven't been properly cleared away. Improperly sealed containers, either on food for humans or pet food. Overflowing rubbish bins.
Mice are drawn to three things: food, shelter, and entry points. If even one of these factors remains available, they'll keep coming back, no matter how many times you remove them. Without addressing these underlying issues, infestations will continue to recur.
Mice enter even clean homes searching for food, water, and shelter, meaning spotless conditions alone won't always prevent infestations. Mice can squeeze through dime-sized openings, making it crucial to regularly inspect and seal small gaps around foundations, windows, doors, and plumbing.
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.
If you see an actual mouse in your home, there are very likely many many more where it came from. This is especially true if it is during the daytime and/or in an open area like the middle of the floor.
It's unlikely that mice will leave your home on their own unless the conditions become highly unfavorable. If there is no food and no suitable nesting material, mice might look for a more comfortable environment.
A: Mice are generally shy and avoid contact with humans. However, they may venture near sleeping humans if they are searching for food or nesting materials, especially in homes with accessible food sources in sleeping areas. It's uncommon, but not impossible.
Mice develop a social order where the strongest male mice are at the top. Another sign of intelligence in mice is easily found in their social interactions. Mice don't always live together, but they will share their nests with their young. Many adult mice can build nests close to one another.
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.
Not only is it disturbing to think about mice crawling on you when you sleep, it is also extremely dangerous to have mice in your bedroom, even if they just hop up on your nightstand, or go through your closet.
Using Objects: Mice are resourceful and will use nearby objects to aid their climbing. For example, they may climb up furniture, curtains, or even electrical wires to reach higher areas.
Surfaces such as glass, glazed wood, polished metal, and plastic don't provide imperfections for their feet to latch onto, making them nearly impossible for mice to scale. For example, the interior of a plastic bucket effectively traps mice because they can't climb the slick surface.
