I've recently moved to a more rural location which is very pleasant,
but I do have a problem with moles digging holes all over the garden.

I'm aware that there are sonic mole deterrents, but have no idea if
they work - has anyone any experience of these, or any other (humane)
suggestions would be much appreciated.

I cut the bottom off a plastic pop/squash bottle and take the cap off,
then expose the run and stuff the neck of the bottle down the
hole/tunnel. I don`t know if it is the light getting or the noise of the
wind but it works for me. If you have lots and lots then I am afraid you
might need to call in the mole man, most villages have a man that can.

good luck
