If it's a black and white snake, it might be a Kingsnake. Kingsnakes are unique as they are the only snakes immune to Rattlesnake venom, which makes them excellent rattlesnake predators. However, that doesn't mean it would be immune to rat poison. You probably would kill the snake.
HOWEVER, if it's vomiting ANYTHING, it's not well. The snake will digest everything.
If you're finding bones, maybe there's an owl down there? Snakes are generally odorless. You are probably having more of a problem with the rats.
Please don't torture the poor snake. Find some other way of dealing with this.
Give us updates on the situation, and we'll be happy to find alternatives.
