I let this little critter go in the yard so he could go eat mice and insects. Brown snake also known as a rat snake, they love to swim. I noticed him as I was midway in during a dive on the pool surface!


The V shaped head sure looks like a pit viper to me. Definitely not a rat snake.
I go straight for the 410, because in my mind, all snakes can jump at least 20 feet and kill you. And I'm cringing at the thought of having to post a thread "Any suggestions? I just filled my pool with buckshot...and the pool store suggested a sequestrant. Should I SLAM first?"
Easy-peasy....salt-shot! Stun the snake and add some extra salt for the SWG [emoji6]
The head in that last picture doesn't look so much like a viper. Most if not all US venomous snakes are pit vipers. Copperheads, rattlesnakes and cottonmouths are. I don't know western snakes, but if I saw that head on a snake I would be very careful.
