My favorite, favorite, favorite bug be gone type product is the uber expensive Catnip oil. (

Not only does it have clinical studies that back up its effectiveness, but I can speak anecdotally to its amazing'ness.
My Dad is a Doctor and six years ago he did this super cool "Doctor Around the World" thing and one of the places he ended up was the small island of Barbuda (off the coast of Antigua). He brought DEET with him. When I visited my folks, I brought Catnip + Lemongrass EO (anything to mask that horrible Catnip scent!) in lotion and used that. My Dad, when I arrived, had over 300 mosquito bites on his body. Though Barbuda is gorgeous, it is chock full of mosquitos (like insanity so many). After I left mostly bite-free, I left my Dad my bottle of mosquito repelling spray. He's pretty analytical so he did DEET on one side of his body and my concoction on the other side of his body. My concoction worked better than the DEET and he was forever sold (as am I)! =)
Funny about the Juniper Sage. I never would have guessed that!
