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.

Usage
There's a couple different things about this product. The value isn't worth it for the simple fact that I used it and it did not help get rid of any insects I didn't notice any difference whatsoever. Then the product seem like it did not last long even though storage was in perfect room temperature after a couple weeks it started turn into a white flaky substance in the liquid and then just would give a white coat over everything and kill the plants but not kill insects. I would not use this product again myself.

Good gnat control without chemicals
The SNS 203 pesticide concentrate works as described. For indoor plants it has gotten rid of most of the gnat population and doesn't have harsh chemicals. Use of this product in combination with letting soil dry completely before watering has eliminated the gnat population. I needed two applications of this product to rid the soil of gnats. DO TEST on your plants first. It did have negative effects on my ficus plant, so I am gathering it shouldn't be used on plants that have a milky sap. I haven't confirmed this with the company, but don't use on a ficus plant if you can avoid it.

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.
