We had a very bad mole problem and we got them out of the yard by taking there main food away. They love grubs and we used milky spore 2 years ago which killed the grubs and spreads like a virus, for I think up to 8 years. Our mole problem was gone and the view left I found this year in my skimmer. Milky spore is made to prevent Japanese Beetles by killing them when they are still grubs so I solved 2 problems at the same time and that without chemicals.
