Preventing mice from entering your home involves a combination of strategic measures that address both entry points and food sources. First, conduct a thorough inspection of your property to identify and seal any cracks or holes, especially around foundations, windows, and doors. Use materials like steel wool or caulk, as mice can squeeze through surprisingly small openings. Next, ensure that all food is stored in airtight containers, and keep countertops and floors clean to eliminate crumbs and spills that attract these pests. Additionally, declutter areas like basements and attics to minimize hiding spots. Installing door sweeps and window screens can further help keep mice out, while maintaining proper landscaping by trimming back bushes and trees that are too close to the home can deter them from approaching. Regularly checking and maintaining these preventive measures is essential for keeping your living space mouse-free.
