Mama To Many (Tennessee, Usa) on 08/04/2015: 
I put 30 drops of cedar essential oil into 2 ounces of rubbing alcohol that I had in a spray bottle. He sprayed himself and the tractor! He later reported that the gnats left him and the tractor alone the rest of the afternoon.
A bonus is that cedar smells great!
