Ditto! JBs killed my hazelnut trees, so I have a personal vendettal against them. I hunt them on my property, and (with permission) on my neighbor's property. I also take any grubs I find in my garden to the chickens too.
I am certainly NOT trying to grow them. I don't know if I'll ever "run out" of JBs, but if I do, that would be fine by me.
The grubs could be of other beetle species:
"White grubs could be of several scarab beetle species, including Japanese beetles, European chafer beetles, masked chafer beetles, green June beetles, May/June beetles, Asiatic garden beetles, and Oriental beetles."
It's the JBs that I see the most of, chomping on my asparagus, bean plants, grape vines, and marigolds. I found gobs of them on the weed Velvet Leaf along the road where I live; I've thought of growing that as a trap crop.
