As temperatures drop and winter approaches, mice begin searching for warm, safe places to spend the season. While the weather outside may be frightful, the fire is so delightful—not just for people, but for mice as well. Unfortunately, a single mouse can quickly turn into a full-blown infestation if left unchecked.
Mice can squeeze through openings as small as a dime, making it surprisingly easy for them to enter homes through tiny cracks and gaps. If a mouse can fit its head through a gap, it can fit its whole body inside. Once inside, they can cause significant problems: spreading disease, contaminating food, chewing through wires, and leaving droppings that create unsanitary and unhealthy conditions.
Understanding how to prevent mice from entering and thriving in a home is the first step toward keeping them out for good. Below are detailed strategies to protect your home from these unwelcome guests.
Seal Up Your House
The most effective way to keep mice out is to block their entry points. Conduct a thorough inspection of the home’s exterior, paying close attention to areas where utilities enter the house—such as around pipes, vents, and electrical conduits. Check for gaps under doors, around windows, and along the foundation. Even small cracks can serve as entryways.
Use durable materials like steel wool, copper mesh, or hardware cloth to fill small holes. For larger gaps, apply caulk or expanding foam sealant. Installing door sweeps on exterior and garage doors can also prevent mice from slipping underneath. Regularly inspect these barriers, as mice are persistent and can chew through softer materials.

Keep Doors Closed
Mice are opportunistic and can dart inside quickly when doors are left open. Make it a habit to keep all exterior doors closed, including the garage door. If the garage is used frequently, consider installing a self-closing mechanism or weather stripping to minimize gaps. Even a few minutes of an open door can be enough for a mouse to find its way in.
Eliminate Food and Water Sources
Mice are drawn to homes that provide easy access to food and water. Store all pantry items—such as grains, pet food, and snacks—in airtight containers made of glass or metal. Clean up crumbs and spills immediately, and avoid leaving dirty dishes in the sink overnight. Regularly empty trash cans and use bins with tight-fitting lids.
Fix leaky pipes, dripping faucets, or condensation issues that provide water sources. In basements or crawl spaces, use a dehumidifier to reduce moisture levels. Without food and water, mice are far less likely to stay.
Note also that eliminating food and water sources can help prevent all types of pest infestations: ants, roaches, centipedes, millipedes, flies, and many more.
Declutter and Organize
Clutter provides hiding spots and nesting materials for mice. Keep storage areas tidy by using sealed plastic bins instead of cardboard boxes, which mice can easily chew through. Regularly clean basements, attics, and garages to eliminate potential nesting sites. Reducing clutter also makes it easier to spot early signs of rodent activity, such as droppings or gnaw marks.
Place Mouse Traps Strategically
Even with preventive measures, setting traps in areas where mice are likely to travel can provide an extra measure of control. Placing traps along walls in the garage, basement, and crawl spaces. Mice are also likely to find the kitchen at some point if they are inside the house, so placing traps under the sink and behind the refrigerator or stove are among the most effective places.
Mice tend to run along walls rather than across open spaces, so positioning traps accordingly increases effectiveness. Use bait such as peanut butter, chocolate, or seeds to attract them. Check traps daily and dispose of captured mice promptly.
Store Firewood Away from the House
Firewood piles are ideal nesting spots for mice and other pests. Stack firewood at least 20 feet away from the home and elevate it off the ground to reduce hiding places. Only bring in small amounts of wood at a time, and inspect each log before bringing it indoors to ensure no rodents are hitching a ride.
In addition to firewood, mice will take shelter in storage items, trash, and other stacks of materials that are stored outside, so keeping those items away from the house is also advised.
Trim Back Vegetation
Overgrown shrubs, vines, and tree branches can act as bridges for mice to reach the roof or upper levels of a home. Trim vegetation so that it remains at least a foot away from the foundation and walls. Keeping the yard well-maintained also reduces cover for rodents, making the area less appealing to them.
