The answer to 'what attracts mice to your house' is that mice are drawn to homes for three main reasons: food, shelter, and warmth. Mice are constantly searching for sources of food, and they will enter homes to find crumbs, spilled grains, pet food, or any other edible items. They also seek warm, protected spaces for nesting and breeding, and homes provide the perfect environment. Additionally, mice are attracted to the warmth of homes during colder months.
Mice are excellent climbers and can squeeze through openings as small as a dime, so they can easily find ways to enter a home. Once inside, they will build nests, reproduce quickly, and can cause significant damage by chewing on wires, insulation, and other materials.
