Help with Grubs!

Has anyone out there found a really effective anti-grub worm remedee? I treat them and they will keep coming back. I simply hate the idea of them being out there in my soil and chewing away on my plant roots. It is hard to keep small annuals alive for very long because they eat up their already limited roots so quickly. When I notice yellowing leaves and the need for frequent watering, I know that the poison is wearing off and that the grubs are back for lunch! Any suggestions are welcome.
