If they come back this year I am going to get a good insect fogger and see if that will work. From seeing them used I would think they would be much more effective because they cover the whole area. It might be terrible for all the helpful insects but they didn't help any last year. Spraying with a conventional sprayer just slows them down a little because so many are missed by the spray. I don't know if a fogger will work but I'm not going down without a fight next time.
