What likely attracts mice into buildings?

Mice are primarily attracted to environments that provide warmth and shelter, which is why areas where warmth is generated pose a significant draw for these rodents. The warmth often comes from heat sources such as heating systems, plumbing, or even general human activity within a building. Mice seek these warm areas as they provide not only a comfortable living environment but also a safer location to nest and reproduce, especially in colder months when temperatures outside drop.

While open windows and doors can potentially allow entry, they do not inherently attract mice as effectively as warmth does. High ceilings and spacious rooms do not provide the kind of comfort or protective environment that mice require and are therefore less appealing as a habitat. Lastly, while the presence of people might inadvertently attract mice to food sources, it is the warmth generated inside structures that truly compels them to enter and stay. Thus, the correct focus on areas where warmth is generated highlights the biological and behavioral motivations of mice in seeking shelter.
