The method of use for automatic flush activation includes providing a toilet odor prevention tablet, including all natural ingredients, and depositing the toilet bowl odor prevention tablet directly into a toilet tank, where placement of the tablet results in a film that reduces an odor emitting capacity of human excrement and delivers a fresh layer of odor prevention with every flush of a toilet.
