I thought I should Add This: I've done research on the brand Endure, and while it does have Pyrethrins in it, it is not harmful if you don't swallow it, spray it directly into your eyes, or inhale it directly. So, Endure is fairly safe, unless you're an idiot. :p
I use Endure , it seems to work the best.
I don't know how I feel about this.....it really opens my eyes to really read the labels and think about more of a natural approach.
I just ordered more Endure about a week ago too.
Well if your showering in the fly spray it's no surprise your going to get sick! *refering to the stories in the op* "well I just have a system in my barn that spays the stuff down on everyone continuosly..." or "I soaked my poddock and horses fly maks in it twice a day..." *bangs head on wall* I bet if you keep your head under water you wont feel so good either.
