I've read a couple of website about this and here are some suggestions. I've no idea if any of them work but there's no harm in trying them out.
1 - Pour urine / or urinate on the mole hills (apparently they don't like the smell)
2 - Stick childrens windmills in the holes (apparently they don't like the vibrations)
3 - Cover a pine cone in creosote and push it stem down into the run, stem down. (apparently they don't like the smell and can't push them back out)
If in doubt :
4 - Ask a farmer to recommend a mole man
or
5 - Use a mole trap. :

Although none of these are instant solutions, it may take weeks if not months or years to finally get rid of moles.
