The Hi - Yield Grub Free Zone II is not labeled to be used for chinch bugs so we are unable to provide a rate for them. It only states White grubs (including the larvae of the Japanese beetle, Oriental beetle, Chafers, Asiatic garden beetle, May or June beetles, and black turfgrass Ataenius) and mole crickets on the product label. For chinch bugs we would recommend Talstar Xtra instead.
