We have heard scratching in the loft and I have caught two mice. The loft is boarded out pretty much fully and insulated beneath the boarding so it is impossible for me to get to the underneath and I can only put traps down, but I want to prevent anything getting in.
I can check for small holes where visible, I understand they can be tiny like a pencil size and the loft is not exactly tidily finished so that is also going to be impossible. Any thoughts on making mouse free zone?
I also notice that the walls at each end of the roof (adjoining the houses in terrace row) there is then the timber roof but a fair sized gap between the brick and wood - what is best to fill this gap? Lots of wire wool and some form of adhesive? I can't get to the outside as no ladder tall enough so need to try and do this from inside.
