Review: Effective, Easy to use, and safe. - I really love this stuff. I had a severe case of aphids that spread rapidly. So much so, I was actually considering just tossing the infected plants which is not something iv ever done because my plants are like my babies. I didnt want to use any store bought pesticides because in the past, even with following the directions exactly, my plants always ended up getting chemical burns. I have two cats who love to nibble when im not around and a 3 year old who shares my loves for plants and is always helping to water and care for them. I needed something strong enough to take care of this problem but mild enough to cause no harm to my daughter, cats and the plants themselves. I did a ton of research and decided this was my best choice. Im soo pleased with how well this worked. The smell is strong but thats mother natures fault lol I just tried not to breath it in, I also wore gloves and sprayed them down away from where we hang out outside. Being its summer, I let them hang out outside for a few days under my table umbrella and would check on them daily. I would say 90% of the aphids were dead by day one and by day 3 any leftovers slowly died off as well. The plants didnt get any burns at all, in fact I feel like they all look healthier and stronger then before all this happened. I would 100% recommend this. I plan on doing this bi yearly to all my plants as a way to prevent infestations in the future. A couple complaints iv read were that the bottle you get is smaller then it looks in the pictures because it has a handle and most bottles with handles are meant for gallons, although I agree the pictures can give off that impression, its really not a problem considering one treatment doesn't require a lot of product, so I don't find that to even be a problem. In fact I like that its smaller because it was easier to pour and control plus storing it doesn't take a lot of space. Another complaint was that when it arrived it solidified, yes mine was this way as well, but I simply left it out in the sun while I set up my treatment area and got everything I needed together and by the time I was ready to use (about 30 minutes) it was melted enough that I was able to use it. By the time I put everything away it was completely melted. It sais in the directions that you can always heat up some water and let the bottle sit in the water for a bit (like heating up a bottle for a baby). Again not a big deal and for how well this product worked is certainly not going to stop me from purchasing again when I run out. In short, it was effective, easy to use and considering its natural and safe, its a no brainer.

### ⭐⭐⭐⭐⭐ Good insecticide
*by C***E on May 15, 2026*

It’s a small but powerful insecticide,,

### ⭐⭐⭐⭐ I believe it works
*by L***A on April 25, 2025*

Smell: heavy soap. I'm good with it. Mixing: takes very little. I'm good with it. But I had a very difficult time keeping it off my skin. It worked on gnats but they returned with a vengeance. I believe it works but I treated on Fri, didn't return til Mon, saw a big difference so I used twice what was called for - mistake. I may have killed 2 of my 20 plants, so I stopped treating for fear of killing more, and gnats tripled. I think I did some thing wrong, and I believe this product works but I goofed. I removed 1 star because I thot it was pre-mixed & was in a spray bottle, and for Me mixing is difficult.
