Leon you could have a look in the cookware section of a supermarket and see if they've
got any "Biokips" or "Lock & Lock" type plastic boxes - although I think probably any
plastic box with a good seal would do. They're not expensive - but to buy one for each
dried food would be - so perhaps you could just get one or two larger ones and bag your
items and then put them in there.
I've got mice at home and they don't seem to be able to smell the contents or they're
unable to chew through the plastic boxes.
The hanging food from a tree sounds like a good idea also - definitely the end of a
branch or whatever as they can climb anything. I think my mice have a pulley
system in place to winch them on to my counter-top or perhaps a trampoline somewhere
as they make absolutely no sound scrabbling up the cupboards - I am not quite sure
how they are doing it
Re: cheese - I think there was a funny bit in one of the Adrian Mole stories where he
goes camping and finds that cheese was the only thing that didn't leak or require a tin
opener
I don't think mice featured though...
