My brother had trouble with them in his attic, put a load of traps up there with peanut butter, apple, aniseed, bacon and they wouldn't go near them.
He had 2 camera's up there watching them.
Also just put some fenns in wooden tunnel's in the runs coming from under the fence from next door in my niece's garden, rather than come through,
they have dug out new runs.
Alot of them are super neophobic.
