 Well, I'm not sure if it's a solution yet. It's just an interesting thought. I'm actually out in my garden right now picking off some of these Japanese beetles, as per the previous caller. But I noticed that we have an unweeded patch in our garden, which we were neglecting. And we have evening primrose weeds that have grown up to about three or four feet high. And I noticed that those things are just swarmed over with Japanese beetles.
