Beneficial Reptiles work in the high tunnel i was surprised with a Garden Snake i was concerned that the Snake would eat the small frogs and then not really be a benefit to the high tunnel. I did some research and it turns out the Snakes eat Spiders, slugs, worms, and other small bugs , they due also eat frogs and small mice. Snake will eat any bugs and mammals that are easy to caught. Take a look at my photos below i am not a snake lover in fact i have a fear of most snakes, one of the young ladies is also fearful of these reptiles.
