I've been through this a couple times. Once as a Cub Scout, when they were more like toys than annoyances. They don't bother me at all.
I am curious how bad I get them, though. I live in a really old neighborhood, so there should be plenty around. But when I moved in, the Japanese beetles were so bad, I applied milky spores all over the yard. It really helped with the Japanese beetles. I wonder if it will have an impact on the cicadas. So far, I'm only seeing them in a raised garden bed that wouldn't have been treated. It's only day one, though, so my trees could be covered soon.
