My Grandpa used to plant a plant called Gopher Purge in his garden. I don't know if its poisonous or they just don't like it, but it worked.

Gopher Purge or Mole Plant contains a latex like milky sapthat is found in the roots, leaves and flowers.
Poinsettias are members of the same genus and contain the same kind of sticky sap which can cause skin irritation in sensitive people. This caustic substance is not a repellant but a contact irritant. The varmint must chew the roots to become ill or die. In order to protect plants from gophers or moles, a thick stand of Euphorbia planted in the gopher's main tunnel is necessary. And, because it dies every two years, it is necessary to be vigilant and replant or your precious protected plant becomes exposed.</TD>

Gopher Purge (sometimes called
Gopher Spurge) reseeds readily. Sprouting in the early spring,small plants can be easily transplanted from the ground to the desired location. Or, you can leave it alone and let it naturalize itself.
In the photo below, you can see the unusual flower buds of
Gopher Purge. After these open and set seeds they will turn brown. If you do want seedlings, you may leave the pods to fall or collect them.</TD></TR></T></TABLE>
