That just sends them digging elsewhere in the garden. I know I have miles of tunnels with prickly things in them. They just dig another one a couple of inches away from the blocked one.
Would be nice to be able to put a barrier between us and the outside, but I think the ciost would be a bit prohibitive, the perimeter is about 400 metres..
At least most folks do not have the trouble we have. The soil where the moles are doing most damage is only about 6 inches deep and below that is brick rubble. The main runs are below that layer and it is almost impossible to get down to them through the rubble.
