Talstar XTRA Granular Insecticide is not labeled to kill grubs or earthworms. There are no products on the market in the USA that are labeled for earthworms as they are largely beneficial creatures, however, this product could harm beneficial insects that come in contact with treated areas. We do have 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.
