James from Dyer Indiana writes
Scotts GrubEx is not labeled to control earthworms, but it is not really a selective insecticide. It could harm earthworms if they are in contact with a treated area long enough to be affected, although they are pretty protected by the mucus on their bodies. Usually earthworms are too deep in the soil and too protected to be affected by regular pesticides.
