I plant radishes in succession every two weeks amongst my squash plants throughout the season and the squash bugs stay away. I started this after a couple of seasons of crazy invasions. If I only plant them once, it doesn't help. As soon as the radishes start to mature, the bugs are back. I discovered this by accident and went back to my garden diary to make sure nothing else had changed, but this was it. For me, it is a surefire squash bug repellent, though, I have to say it makes no sense to me either.
