So we've been really struggling to identify an access point for months that's letting something into the wall cavity that our pipes run through. I know it's either a mouse or a rat but I'm thinking most likely a mouse. Thankfully we seem to have found the entry point and dh filled it, but today we heard so much noise that we think we've trapped the mouse in the wall cavity. We did the filling in the middle of a dry sunny day when we thought it would be most likely to be out.
My question is what happens next? Are they going to chew through into the house or will they just die?
