Doesn't work.
If you try it, make sure the stuff is biodegradable or you'll have a greasy mess on your hands.
We did finally find something that does work. It's called
Deer Scram. It's made up of powdered hot peppers. We had a beautiful stand of flowers and vines in front of one of our cottages. We looked out one morning and three does were helping themselves to breakfast. Ate it to the ground! After applying Deer Scram, everything has grown back and the deer have left it alone.
Now, If we can only get the damn armadillos under control. Our property is a mix of sugar sand and red clay that gets hard as a rock. So, when the armadillos find a nicely tilled compost enriched moistened flower bed, they go to town looking for grubs. We have had some success with a low fence in some areas, but now we think they're hurling themselves off the back porch to gain access to our herb garden.
