And don't forget you need to be able to mix this stuff into a liter. The bottle that comes with the zoo med fogger is 1L. And please correct me if I'm wrong with this...I don't believe that a disinfectant would harm a snake (assuming that it is if safe for the snake) even if there are no bacteria. I would not recommend giving medicine to a snake that doesn't need the medicine, but this just sterilizes the lung area of any bacteria (or at least disinfects a good amount of it).
