Bronco works around here in New Jersey. The only issue is that it evaporates SO QUICKLY! Ugh, sometimes we'll be riding and her tail will be swatting flies just five minutes after getting on because its hot and nasty and sweaty. I'll have to try that Avon thing out especially since all the horses I would use it on have no fly spray allergies. One question, does that make it last multiple days? That's actually a quality I don't want in my fly spray. Daily spraying is for me.
