What KIND of snakes? They can be your garden’s best friend, right up there with frogs & toads.
As long as they aren’t rattlers, copperheads, or moccasins, they are great mouse, vole, and bunny eating machines.
No bunnies, voles, or mice around here so don’t need them for that. I don’t bother checking for rattles but the odds would be in favor of any snake out here on a Texas river that it’s going to be a rattler, copperhead or water moccasin.
