Try spreading lion dung around, you can buy it in dried form from garden centres. Also as suggested human pee, they seem to dislike girls more than boys, I've successfully got rid of badgers from a garden this way!
If you can borrow a dog and let them pee over your garden this helps too.
Foxes and cats don't seem to like shiny things either especially mirrors.
You don't say if you are in a rural or urban situation, you could try asking your local authority if they can get rid of them if there's a lot. We are rural and the local farmers take care of them when they breed too successfully.
