 How about you mix that up? How about you put in some other vegetables in between and at least slow the travel of these bugs between your veggies? And no, you're not going to stop them. No, it's not going to be 100%. But is it better to do something to slow them down or just to let them ravage the whole crop? I would put something in there to slow them down and to make it a little harder for them to move from plant to plant. It's like a no-brainer to me.
