We had a hornets nest vacuumed this week. It works really well. And free too. He sells the bugs to make antivenom.
For Yellow Jackets, I use gasoline. But don't light it. Pour in some gas and dump a cup of sand over the nest. You can do it the other way as well but I don;t.
Well, I don't have the problem, but I'll keep it in mind. I'm sure one of these days....
