The other Sunday, when the kids were over, they discovered an in ground wasp nest in the yard.  Hoping to kill all of the wasps, the kids stuck a large stick in the hole.

Well, the determined wasps not only excavated around the stick, they ended up digging a hole the size of a volley ball in my yard.

I went out tonight and sprayed the hole with bee killer. It is much more effective than a large stick.
