I have a pondless waterfall feature in my yard with lots of boulders planted along the side. I realize that I have created a perfect spot for snakes to hangout, but it has never been a problem until this year. I have spotted several garter snakes on the edges and slithering across the stone steps. Problem is the steps lead to the swimming pool and we often are walking down them barefoot. They are startling the heck out of my wife and I and when the little ones(nephews and nieces) come over to swim this summer I can only imagine the nightmares they will have. What to do?
