Natural Insect Repellent Oil for People ~ Pet Flea Protection?

Now I'm taking the herbs to a different level.  There are so many uses for herbs (and oils) it's so much fun to research and try them.

To make the insect oil, I used a 1/4 cup to measure my "parts."  You can see in this quart jar, how much it fills the jar.  We've have good luck with homemade basil mosquito spray, but so far nothing has worked for flies or gnats (or fleas on our dogs and cats).
