Also, you are right that it has sickened and killed some snakes. Every case I've heard of though was from people spraying PAM on a cloth and wiping down their snake or they sprayed the cage and immediately put the snake back in. I've not heard of it harming a snake when used as directed. I think some people think the PAM on a cloth thing is safe because PAM was sprayed directly on Sulcata and Leopard tortoise imports to rid them of the Heartwater tick. Just because it's safe to put on a tortoise doesn't mean it's safe to put directly on a snake.
