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 your lawn after a heavy rainfall which will eliminate some of the population. Clearys 3336 DG Lite is a fungicide and has not been tested to kill earthworms
