 can arrive at a pest repellent that is pleasant smelling, far better smelling than the DEET-based sprays. And again, about the yarrow, is it the leaves you're using or are you using the flowers on the top? You use the above-ground plants. You want the leaves and the flowers you can use, too. But really, it's the leaves that are most potent for this purpose. That's what I thought. This is good information.
