I've had mice chew thru the expanding foam that comes in a can.
They make some with a bitterant in it now - I have no idea how effective it is
This happened in my house as well. Thought I was being clever blocking off their way in. OK for a while but then there was a new mouse and I saw exactly where he came from! Not knowing what else to try I got some small wood blocks and tried to make a good physical barrier first, then more spray foam, from inside and outside. Seems to be working, for now anyway.
