Spraying chemicals on my horses that I wouldn’t spray on myself just never felt right. That is what started me on the path of making my own fly spray. After years of trial and error and countless hours of research, I finally developed a combination of ingredients that really worked! Then I met Kirk, a chemist extraordinaire who loved what I had accomplished but was able to take it that final step of creating a completely emulsified product – eliminating the need to shake between sprays.
