I know, I’m kind of at a dead end as I’ve had 4 companies out and sealed all potential entry points established so the last thing I can think of is that they are getting in from the adjoining property via the attic. Hey ho… I shall continue on until another house comes upAh sorry to hear you've still got probs, the traps will help, maybe have a good look to see if you can spot anywhere they're coming in?
Funny you should say that as I really do think at this point it’s access via my neighbours because everything else has been sealed. I had heard sealing up your attic entirely is bad tho?I used to hear scurrying in my loft all the time, it never really bothered me because I couldn't see them and they couldn't get to me but last year I had some fire stop safety work done where it basically sealed the whole loft. I haven't heard anything since. It might be an idea to check if the mice are getting in from your neighbours and look into getting your loft sealed. Mice can be a problem in any house so moving might not be the answer.
