I had wild boars on my land until I fixed my fences. They are very pesky and will do a lot of damage. I even suspect that they climbed my apple trees and ate the apples.

My vegetable garden is protected by a metal fence.
I have metal posts hammered in every 2 metres.
To this I have attached a wire screen about 90 cm high.

This is the same stuff they use on building sites to reinforce the concrete so it is very cheap.

Since I have had a continuous fence the wild boars and mountian goats have not entered. They don't like the spikes on top of the mesh.

I have seen a lot of wild boar damage but I have never seen one.

I suspect that they come in big family groups at night.

The previous owner of my land said he used to shoot them.
He used to attract them on purpose and sit in a tree with his gun.

I still have the big galvanised bath he used to immerse the boar in after killing it.
(it is necesary to put the corpse in hot water to get the bristles out)
