Hi Judy, Gardens Alive sells nematodes called Grub-Away. Never tried any of their products, but since I have a $20.00 coupon, guess I will. http://www.gardens-alive.com Dave Anderson TLCC http://www.tough-love.com > Does anybody know of an organic way to get rid of grub worms > (besides digging them out!)?? Judy One disadvantage to the Bene nematodes, They don't start working until the soil temp is above 55F. You can get second and 3rd generations with this stuff and reduce next years crop. Multiple tilling before plant out. Barriers to prevent migrators. OR You could try a brief flooding. Byron
