That is very cool. I have never heard of a snake eating ticks. Is that just because the ticks are on the voles? My wife has a bad snake phobia (even stranger, frogs too). Once the garden gets going, she usually won't venture out there much. We're talking Garter snakes and an occasional Brown snake which are about the size of a pencil. I don't know what she would do if she ever saw a blue racer lol. I'm just the opposite. When I was a kid I would spend days looking for them. I used to lay plywood out in grassy areas and check under them every morning. Worked like charm on garters and an occasional milk snake. Drove my parents insane LOL.
