@HistoPol @jnye That's what the 1/4" hardware cloth is for. I also had to make a second gate lined with cloth, making sure there aren't any gaps anywhere around it larger than about 1/4 inch, and it is buried into the ground about 6 inches. There is a Phoenix-based business (they do rattlesnake removals and snake fence installation) that posts a lot of YouTube videos, one of them explains the requirements of a truly snake proof fence.
