I have used 2 1/2 pails of this product. I am due to put down one more application this spring. I find that it works fair in my grassy areas and not at all when spread into my pine straw natural areas where the moles live.
This would have received a higher rating but it is not only activated by water, an excess can also wash it away. I needed two 22# buckets for one application and it lasted less than 5 days. A hurricane-force storm like we've never had before washed it all away. Now, the pests are back with a greater vengeance. Huge waste of money on my part.
This is a tentative rating, as I spread it only 2 days ago. I've used castor oil-based formulas before, including making my own concoction, which became too expensive, & found them to be effective, so I have high hopes for this product.
3 stars because I think this formulation is good (and fairly standard for the industry)... But i think the labelling, and instructions miss the mark, and are frankly misleading.
I tried to follow the instructions for applying it in stages moving away from the house, but i end up just doing 3 stages directly around the house... Since they never left that area. I could definitely tell this product irritated the moles, because their tunnels became more erratic... But they never actually left the treated area. (I apply fertilizer and pesticides professionally, and am licensed to do so... So the application itself wasn't the issue) but all that really accomplished was to make more lawn damage.
It seems that repellent is a pretty poor way to get moles to leave an area that they're otherwise very happy to in. Though I would bet that this product would be successful at keeping new moles from entering your property... You'd just have to remove the current moles by other means.
