Well we have trapped them, tried every old wives tale preventative and nothing works. Eventually they come back in from the fields around us. Even our neighbours expert mole killing cat cannot deal with the numbers we get.
Did pour 200 gallons of grey water down the runs and that kept them away for a couple of years though. Did whiff a bit.
Most of the tunnel blocking ideas are great for forcing them to dig more tunnels, often just alongside the old one.
And as for the soil from the hills. I tried it and it set like concrete. And here it is full of broken glass, crockery and scrap metal.
