Organic Insecticide Liquid Concentrate – Plant Spray for Indoor & Outdoor Use – Controls Fungus Gnats, Aphids, Whiteflies, Mealybugs & Spider Mites – Houseplant & Garden Insect Killer, Fast-Acting

The first time I used the bio insecticide for fungus gnats, I was hugely disappointed - it didn't seem to make a difference at all! Then I switched to the systemic bonide insect control granules, which worked a treat at first... but the treatment didn't last 8 weeks, it's not cost effective for the number of plants I have, and it only kills larvae. I went back to the Google drawing board and found a ton of other products that also only kill larvae. So I went back to the arber website and poked around a bit, because arber is the only product that claims to kill both larvae and adults. I found that it's recommended to water with the insecticide and fungicide (and spray with the insecticide) every 5 days until the gnats are under control, then use every 2 weeks for upkeep. And THAT combo really did the trick after 3 applications (though my zz plant, which got redonk infested when moved it to the living room when work was being done in my bedroom, could have used 4 full every-5-day treatments the first time). It's clear by the empty gnat traps in my plants that this combination really does the trick for larvae and adults. And it's way more cost effective (and less work than mixing in granules) over the long term. Win!!

Not sure what kind of magic is on this bottle, but it def works! My peace lily had been drooping for almost a month now, and I haven’t been able to find the right products to spark it back up to life. I found this by searching Amazon, read the reviews, and ordered. It came in on Friday. I followed the instructions, and left for the day on Saturday. I remembered I hadn’t taken a before pic so that was the first thing I went to, and I was in disbelief. Not only does it work, but it took less than a full 24 hours to see the effects. I’ll post the pic that I took a little under 24 hours and will try to come back to show final results.

I didn’t want to take off many stars, because the product worked great. It didn’t leave a sticky residue and honestly didn’t smell very bad at all (especially compared to how strong Neem oil is!!). Got the job done and didn’t disrupt my house with any strong smell! BUT!!!! Within minutes of applying and wiping my leaves, I saw all these residue dots which didn’t make sense to me. There was no residue on windowsills or my floor after spraying and wiping it off, but it showed up on my Monstera leaves? Does anyone know what this could be?

Insecticides can be an intimidating thing for new indoor plant parents! This product makes it much easier! This insecticide is gentle on root systems and doesn’t cause issues in new growth on established plants. I do NOT recommend using on plants that you recently repotted within the first two months. It can hurt the already shocked root systems. However, when used, the amount of gnats go down dramatically! Follow all instructions and you are good to go!

It's not killing my affids

I used this product to treat a mealybug infestation on my indoor cactus. I did a soil soak and sprayed some directly on my cactus. To be on the safe side, I did this again when it came time to water. So far I have not seen any more mealybugs or caused any damage to my cactus. It was easy to mix and didn't have some overpowering smell to it. Update: 12/29/25 Noticed a handful of mealybugs have reappeared. Not sure now how effective this product is and if I'm going to be using the entire bottle only to see more mealybugs down the line? I guess we'll find out. Update: 2/25/26 Well I'm at the end of my bottle and I still have mealybugs and my Peace Lilly that has a gnat problem still has that going on even after using this stuff. Unfortunately it doesn't look well for my Rainbow Cactus, I think it's gonna die. My Golden Rat Tail Cactus lost three of its arms out of six. Hope I have better luck with something else.

I use this on my houseplants and garden, and it really helps control fungus gnats and spider mites. It has a natural smell (not chemical), and doesn’t harm my plants. Works fast, especially when used regularly. Love that it’s safe around pets and doesn’t leave residue. We stopped using chemicals and this fit the bill.

I experienced limited success using this product. Applied throughly to both the underside and atop the leaves multiple times doesn't appear to curb the bugs appetite at all. I don't think that I will purchase this product again.
