Peppermint oil works very well. I use it in my camp during the winter months... I was setting traps every winter, and catching mice all the time. Which ment taking trips once every couple of months through the winter, and emptying the traps and resetting them. Last winter, the second winter using Peppermint oil... I only visited the camp once, only set 3 traps, and only had one mouse in a trap....
