They are creatures of habit and follow scent trails and regular paths. So you need to find where they are getting into the garden and block it off. We have had to put about 100 metres of chicken wire round the garden perimeter. I know they can and will chew through it and dig under it. Here they cannot as there is the remains of wall all round us. To stop them approaching the fence we were told to put half filled clear plastic bottles as they are supposed to frighten the badgers away. It looks a bit odd, but so far no attempt has been made to damage the fence. The fencing is also loose which makes climbing it very difficult. I did hang Jeye's Fluid soaked cloths in the places where they had been coming in under the original fencing. BUT, since they have not been back so far this winter or spring I have not replaced them.
If you look on the Interweb things there is a lot of advice, but do take care, a lot of the things proposed are illegal (including the Jeye's Fluid thing).
