Hi Bernard
I sympathise with your problem. One neighbour isn’t keen on hog holes, I suspect due to the occasional rat that’s been visiting – even though there were plenty of other ways it could get into the garden.
I think the best thing I can do is give you links to some previous rat topics. You might find something you can try.
Rats.
