not sure if you have livestock, but if one does feed it to cattle and horses, one drawback is the droppings will not decay-— it obviously kills any bugs recycling it.
I do have a small amount of livestock and yes I was planning to use it for fly control, but I also use their poop for compost to fill my many raised beds. hmmm, maybe I better hold off using it with them. I read it makes their coats thick and lustrous if fed to them regularly. Thanks for the tips.
