Natural VS Chemical Fly Spray. What do you use?

So its fly season and I thought before i went out and got my old friend bronco i would ask y'all what your favorit fly spray is. So so you like Natural? if so what do you use or do you make your own, if you make your own what do you use. How about those how like the chemical fly sprays? what your favorit brand. Also what ells do you guys do ti make fly season livable lol. No unkind answers please, you win more with honey then you do with vinegar.
