I tried using this product for about a year with no success. I'm sure this works great in loamy lawns but I have plants, not grass, and live in suburban California, which means lots of clay! It is extremely difficult to find mole runs except in winter when the rain softens the clay. For my particular situation, i've found the Cinch mole traps to be extremely effective - they worked in a week. I did modify my method to try to match what other reviewers and youtube videos show, but if you don't have a nice soft lawn, there are better tools to catch moles with.
