Thanks for the info.
We tried a product Bonide (The can says for termite and carpenter ants, but reading label lists bees/wasps). This can had a long staw that attached to the top to be placed in the hole. The problem is there are a lot of holes, so I think we missed some. And yes my husband got stung once. Early this morning I tried Sevin and dusted this on top of the holes and I'll see what happens. Questions: Am I right in assuming that the holes I see in the morning that have a newly dug dirt piles are active and the one that don't are dead?
