TJ, that's what we did. 50/50 with imitation vanilla. It's cheap.
BTW, I have no personal knowledge of whether it works. Stinging insects don't mess with me. But, Charlene swears by the stuff and every biting stinging bug gravitates to her. If a wasp stings her, she she swells up pretty badly. I was once told that dryer sheets repel mosquitos. Charlene found that they don't work.
Bob, I once heard that only the females bite/sting and only the males make the buzzing sound we hear. However, being hard of hearing, I don't hear anything. So, if you hear a skeeter buzzing around you, no sweat. Evidently, the real problem is when you don't hear any buzzing around you.
