I'm for dryer sheets they're the only thing that has ever worked in my shed I have never had any trouble with my TT but in my shed I've tried 110v sonic rodent and roach repellants I even had two black snakes take up residents in there one year, heck one day I saw the snakes mating under my utility trailer so I know they had to have worked up an appetite but when they finally left the mice were still there, so I put a trap out I never saw that trap again. Anybody remember Mighty Mouse darn maybe that was what was living in my shed. Anyway Dryer sheets seem too be the only thing that keeps them off of my equiptment, you just can't forget to change the sheets about every month or they will use the sheets for nesting material. Anyway they're still in the shed but the sheets keep them off my equiptment and that's all I care about. Good luck with what ever you end up using.
