You cannot use Talstar for grub control as it is not on the label. You are able to apply other insecticides before or after applying Milky Spore Lawn Spreader Mix but we would suggest waiting 2-3 days between applications. We do have other several products that are specifically labeled for grub worms on our website: Grub Worm Control. We also recommend that you contact your local cooperative extension office and inquire about the best time to start treatments for grubs in your region.
