Keeping my indoor houseplant collection in great health.
I use it as a preventative measure. It helps me to save my plants from any above-ground pests (when used as a foliar spray) and in-ground, too (soil drench). I add a small amount with every other watering. Works for plants in leca.

White Fly Killer
I used this product on a citrus tree planted in a very large pot. The year before last I had basketfulls of tangerines and this past year I had none due to a serious white fly infestation. I tried the water blast method because I did not want to use any chemicals but when I realized the tree was going to die if I didn't do something I went on line and did some research. My tree is now sprouting new beautiful green tender leaves and hopefully I will not have the white fly infestation I have had in the past. I will update as time passes.

Works for moths/butterflies, but...
This works just fine. Actually, because it works at all, it works better than any product or home remedy that I've tried this year for cabbage, kale, and collards. I have very aggressive moths/caterpillars. So, this treatment only lasts about 1.5 days and then the holes start back increasing. And at that rate, this product is much too expensive for a 10x10 foot home garden. However, I feel that it would be awesome for a much smaller garden.
