I use MachII, but a customer put down GrubX (Merit) and had some damage, not severe, but there none the less.
Another customer has one of the larger Co's in the area treat his lawn. I have been trying to get him for years. I stopped to cut one afternoon, and the tech was there. I asked what he was applying, he replied" grub control". I didn't get anything further from him.
Well, this lawn suffered big time. The critters are a diggin'. If I can't sell him after this, I never will be able to.
