I have a problem with mice getting inside a sealed room boiler - I have sealed the garage door and some other possible entry points around the garage, but I was wondering if it might also be possible for a mouse to climb into the boiler through the horizontal flue, which is only a couple of meters or so from the ground outside. Or I was also wondering about the copper overflow pipe, which I think is either 15 or 19 mm?? Thank you.
