Quali - Pro Bifenthrin I/T 7.9 F is not labeled for earthworms, but it is not selective in what it kills really either. Earthworms are pretty protected by the mucus on their bodies. There are no products on the market in the USA that are labeled for earthworms as they are largely beneficial creatures. There are a few known control methods that include cutting back on irrigation so that the worms will go deeper into the soil for the moisture they require to survive, or fertilizing the area after a heavy rainfall which will eliminate some of the population.
