SunHwaKwon, Smite is 13.25% permethrin, and Jeyes Fluid is far from organic/natural! Not sure what you think I should be using instead? Our coop has been repeatedly drenched in both of these products.
Oops this is the Smite product that I found when I googled it and I assumed it was what you were using since you were also using DE (usually that is the organic people that use that).
