We have just had a 33' AGP installed on the site that my inlaws (many years ago) had a 27' pool. Back "in the day" my inlaws kept pine needles on plastic tarp around the edge of the pool to keep the grass from growing. I have been told that pine needles are a snake pit, and that is why they had snake issues with their previous pool (for the record, I'm terrified of snakes and my heart rate is up from just typing this). I would like suggestions for what we could use to put around our pool that will not become a haven for snakes. I've already ruled out gravel, as I might not be able to see snakes hiding out among the rocks. Thanks in advance.
