I'm with Bob L on:
We live in Texas, and every time I see a water snake, I shoot it . They eat my fish, scare my wife and grandchildren. I'll quickly leave non-poisionous terrestrial snakes alone or relocate them, but since our house sits within 50 feet of our pond, snakes gotta go. Plus, I have several hatchery ponds and our watersnakes can eat lots of baby bluegill, bass, etc. I won't let them stay here .
& I don't think I've ever disagreed with DD:
I generally only kill snakes that are poisonous when they are around the house, barns or ponds. Rattlers in the pastures, brush and on the roads are safe from me. I have killed 2 small rattlers that were aggressive enough to come after me. Water snakes that make me hurt myself have a death wish. As long as I remain at the top of the food chain, I'll make the decisions around the ponds .
Greg has the same feelings I do when I hear this:
I agree Al it is tough for me to hear
the only good snake is a bad [dead] one..
I do destroy poisonos snakes anywhere my loved ones might tread but I at least remove they're hides so they are remembered.

The water snakes have to go for reasons I already said. I have several black racers around the pond eating frogs but can't bring myself to kill them .. they're alot of fun to play with when you can catch one. Man are they
FAST! Sorry I mislead you for so long Dave .. it wasn't intentional. I already knew that.
