Are you sure that it is wild boar and not badgers? Whether boar, badgers or moles they will all be worm chasing! The drastic move is to kill the worms! However worms are good for the soil and your soil must be in reasonable condition and this ultimate solution is a lot of poison!.
If it is badgers you could distract them with pea nuts which are a preferred alternative to worms.
Wild boar can be controlled by an electric fence. The wires do not have to be very high and and a mains based unit will cost around €100.
The moles may only be one mole as each mole has a large underground territory covering a large number of square metres. There a plenty of mole removal techniques varying from human hair down the holes to individual mole mines. However if you are in a densely populated mole area they will quickly re colonise and renovate and extend existing burrows and throw out more soil.
I have adopted a laissez faire attitude and rake out the spoil heaps on a regular basis, this seems to work in that we do not get too much damage.
Beware! - moles hating can become an obsession!
Good luck |
