Sounds like mice or rats.
Whatever they are, if you put some bait down and that kills the ones there,
then that normally solves the problem and no others tend to return - so you
don't have to bother trying to seal every possible hole
You'll never get them all. A mouse can get through a tiny hole if it
wants to. I've tried it here and it may have slightly reduced the
number but with a rubble stone built property once they are inside the
wall they have free run.
