Dryer Sheets. Find out where your problem areas are for mice, then layout your dryer sheets flat. Make sure to check the scent and freshness of them, as they can also be used as a nesting material for mice once the scent has worn off. You can also use these as a plug where the mice are sneaking in. Mice hate the smell of dryer sheets so this can keep them away! Try and get the smelliest ones that you can buy.
Copper wire mesh/Copper Steel. All you have to do is roll up the mesh into a wad and stuff it into any holes or cracks where the mice are getting in. Use as many layers are you can to really jam it in there. You can also use a pepper spray as an extra deterrent.
Aluminum Foil. This may sound really weird and funny, but mice don’t like the sound aluminum foil makes or the taste! You can either lay it out flat for them to run across or you can bunch it up and put it in the holes/cracks where they are getting in! You can also lay it out flat in front of where they are getting in!
Furry Friends. Some people have a real mice problem in their homes/cabins. Cats are great animals to solve this problem, if you don’t have one you may want to think about adopting one at your local animal shelter and let nature do its thing! Not only are you getting rid of your mouse problem but you are also giving an animal a home!
