Any big independent garden center will have an animal repellant area.
There will be many to choose from, even for moles.
The best by far is made by Bonide ( yellow bag ) Mole and Vole Reppellant
It contains peat moss and castor oil. Apply at twice the reccommended rate. ( no worries there, it's 99% organic )
You spread it around the entire yard, not just where you see the trails. The castor oil irritates the skin of burrowing animals and they find more comfortable places to live, like the neighbors yard.
Also, consider treating your lawn for grubs this June ( depending on where you live )with a prodict like Gubex from Scotts. Get rid of there food and the moles will go away.
