Have you considered outsourcing? To a cat (or cats) or a pest control company. The pest control company will probably check and close off opportunities for mice to enter the unit, which cats won't do, so you might want to consider retaining both options.

Warehouse cats can be nice warehouse companions too (depending on what happens in the unit).

I've had to do some mouse removal work in my forest adjacent home, and it's not pleasant, but neither is having mice around.

We took our cat in, but she absolutely hated it. Then we thought she escaped for a few hours until we found her expertly hiding underneath some machinery.

In Costco they sell this cat food called ‘Maintenance cat’. Maybe we need one of those cats.

Yeah... around here shelters separate out 'barn cats' from 'pet cats', barn cats are tolerant of people but not really socialized to appreciate people. Rather than taking an existing pet cat and putting him or her to work, I'd try adopting a barn cat and putting them to work. Often, barn cats do retire and become pet cats towards the end of their life, if circumstances allow.

Of course, cats can cause a different sort of trouble than mice. :D

Barn cats are pocket sized tigers. I've seen one filet a grown up guy that tried to evict it. He looked like he'd been run over by a harvester.

I'm dying at the idea of a maintenance cat. In my mind he's wearing little overalls and carrying a wrench.
