I just dealt with this myself.

Here's an eco friendly way to get rid of them:

Take a large Gatorade bottle or milk jug.
Cut the top 2/3 off
Put some leftover chicken, bacon grease, or whatever in the bottom half to attract the buggers
remove the lid from the top half.
Fit the top half inside the bottom half and seal the seam up with tape.

Wait until dark when they are all in the nest and place the trap over the hole. You might want to pack sand or dirt around it so they an't escape around the bottom.

During the day they will fly out of the nest and into the funnel. Once inside the jug, though they won't be able to get out.

I did this last week and within 2 days had trapped several hundred of them. You can tell when the nest is about to die out becasue the large queens and drones start appearing in the trap.
