In order to get rid of a ground nesting bee hole, it's important to create an environment the insects don't like. The bees are attracted to dry land, so watering the yard and nest will be beneficial in getting them to leave. Insecticides should be avoided since bees populations are decreasing around the world.

If the bees are inaccessible, you will need to contact a pest controller who will have the necessary chemicals.
