I have heard that there is nothing an individual can do, it has to be a community effort, spaying the ground with a substance called "milky spore". I did however have a plumb tree that would be destroyed every year by them. I cut it down and it seemed to help. There for a few years we were also over run with 'em but they seem to be diminishing. Not to many this year or last. Maybe they are nomadic. I have impaled them on a hook with success, but not with any consistancy.
