While I'd agree with clearing excess feed away from obvious, easily accessed places at dusk, that alone won't stop them being in the garden, where they aren't usually a major problem. You still have to tackle the issue of them coming inside. Rats are different, of course.
I also tried one of those sonic deterrents in a previous house, Doogie - also a fairly rural location, and an old house, but it didn't make a blind bit of difference!
Maybe Scottish mice are just more determined....
