How to rid your yard of moles

Does your yard look like this?  

 If so, this is the most likely culprit...moles!

These subterranean creatures burrow through the dirt looking to bunch on insects in your yard.  They aren't actually eating your grass or plants, but are uprooting your grass as they make their tunnels.  Are you ready to rid your yard of moles? 

There are 4 methods of getting rid of the moles in your yard:

1.  Trap and Kill - This takes a lot of patience and has a certain yuck factor that most people aren't willing to do.

2.  Poison - The home centers are starting to carry a product that is in the shape of a worm that you place in an active tunnel for them to eat.  It contains poison that will kill the mole.  There are mixed reviews on the results and you have to make sure you place it in an active tunnel.

3.  Repel the Moles -   If you make your yard less desirable than your neighbors, your mole will move along. The most available and most effective mole repellent is castor oil which moles don't like they way it feels on their skin.  It is available in a liquid or you now see granules which make it easier to apply over a large area.

4.  Get rid of their Food Source - By far the most effective way of getting rid of moles, is to get rid of their food source - Insects.  You can apply a granule or liquid insecticide to your lawn to kill  the insects.  Make sure you get an insecticide that will kill grubs as that is their most favorite meal and not all insecticides kill grubs.

None of these are easy, quick or 100% effective so realize you aren't going to see immediate results.  The best results seem to be when you combine methods 3 and 4 above.  What have you tried? What has worked for you?
