Need help with ground hornets

[swglenn]

Find the entrance to their underground nest. After dark, when they have all flown in for the night, spray wasp and hornet killer into the hole. Some people say they put a window screen over the hole so they can't fly out and then spray the hole. If they don't all die spray again the next night. I got popped by one Monday while weed eating around a tree. They do hurt worse than a wasp! I have seen where armadillo's dig up a nest and eat the larvae.
