I put it on my outdoor dogs bed. She has way fewer fleas and noticeably less ‘scratchy’ now. I put it around her food bowls on the porch too to keep ants and other stuff out. We sprinkle it in the nesting boxes in the chicken coop.
I hadn’t thought to eat it. I’ll have to give that some thought though.
I studied up on “ingesting” it.
I figure if they can give it to million-dollar racehorses, it couldn’t hurt me!
