We've done it and tedious is right.
How many neighbors would want to spend the money when so many do not have gardens, nothing in bloom at all? They have shrubs and trees, beautiful properties but they just are not gardeners. I doubt many of our neighbors would even know what a Japanese beetle is or be aware of the damage they do. We do not have moles so there is no "head for your neighbor's yard".
It's a major undertaking with iffy results.
