Wishful thinking. It is basically a natural predator scent, so IF the animals are naturally afraid of coyotes, they might stay away. If not, and they are the 10% of the population that are what are called "curious" or "stupid", it won't work. There is no magic granule in my opinion that works as a repellent for any extended amount of time. Most of these type of repellents have to be reapplied every few days or weeks to be effective.
