This is a tough product to review. I put it around the flowers in the pots at my pool. I was having squirrels literally toss the flowers out, I assume looking for nuts from last year. Not being terribly squirrly myself I can't claim to know why the squirrels were yanking my flowers out but that is my guess. I put this stuff around the flowers and have not had any issues since. I am making a leap of faith that the granules are the reason why the squirrels have not returned. They are still in the yard but have not bothered the plants. Since I am not sure that the product drove the squirrels away I can't give it 5 stars but since I am pretty sure, I will give it four stars. BTW it does not have the strong odor I have found on similar types of products I have used in the past.
It has now been about three weeks after I poured this around one of my dogwoods. The tree was being used by the squirrels to jump on my roof. Since I put this down, I have not seen one squirrel in the tree.
If reviewing a product, it may have been received free of charge. That will NEVER have a bearing on my recommendations.
