Ás I understand it, David is questioning something else. The effects on insects and mites are demolishing and immediate as anyone can see. It even kills cockroaches. Instantly. Since the treatment is on the present pest and in such minute quantities, it is as organic as other products can be. So much so that if the small quantity of water is not added all of the alcohol would evaporate within seconds.
Of course the traditional method has been to paint the pests one by one but spraying the foliage, trunks, etc. affected, with a hand sprayer makes it very fast to treat several plants, etc.
