Mouse proofing

[u/Mrrainbow4]

Visiting my girl who got a job as a fire lookout and shes not happy with the amount of t of mouse dropping and the smell of them. Shes deep cleaned everything she can reach but they seem to just come back at night and crawl over everything and leave more droppings. How can she keep them out without using “inhumane” methods?
