My rule is to kill on sight any venomous snake if I can safely do so, but WildCare Bay Area in San Rafael, California takes a different approach. The staff met a rattlesnake that had become trapped in a plastic mesh. It was unable to free itself, so they restrained its head, then cut away the plastic net.
One of their more challenging tasks was to remove some of the plastic from the snake's mouth as it tried to bite them.
