I’m not sure what you saw but I’ve never suggested milky spore to get rid of moles. Milky spore, used properly, can rid your lawn of Japanese Beetle Grubs. While it is true that moles eat grubs, ridding your lawn of grubs doesn’t get rid of moles since moles also eat earthworms. Ridding your lawn of moles will take timely applications of mole repellent. Here are links to a couple of blog posts that discuss mole control and grub control.
