This Bee almost completely distroyed my garden last 2 years. Tried everything. My son thought of something I had forgotten since it was never mentioned in ways to combat this evil bug. 7 Dust, start early in the season on your 1st flowers that you notice being cut. Dampon flowers lightly and load with 7 dust. You will see they have taken some but watch closely and in a few days they will be gone, When their favorite flower bloomed I dusted them just in case but if they came I could find no sign. I was told their was nothing I could do so I want people to know that this works. When I first went to bug sight their was a woman asking for help and now I cannot find her note. If you know who please let her know. I know what it's like to have this bee completely distroy your hard work.
