In my experience fresh cab doesn’t work much, if at all. Same with dryer sheets. Moth balls help, but they do stink. If it’s somewhere you can tend to regularly, I prefer good old classic victor snap traps with Pb or tomcat mouse attractant. Place a bunch around the perimeter in key spots. I call it “running my trap line.” It’s kinda fun! If you smell a musty odor in the air and find your mice half eaten, you know you have shrews…
Otherwise a bucket trap is the ticket. It’s what I use in the camper up north during the cold months.
