Bio Insect Repellent

I tried this insecticide/fungicide and so far it seems great! Thankfully I don’t have a major pest issue right now, but I plan to keep it on hand as part of my regular plant care routine. It’s easy to mix and spray, and I love that it’s organic and safe to use around kids, pets, and pollinators. For me, it’s mostly about prevention — I want to stay ahead of spider mites, fungus gnats, and powdery mildew before they ever become a problem. I also noticed this brand offers plant food, which I’m excited to try next. Their product line feels very reliable and plant-friendly. ✅ Why I love it: • Organic and safe for use indoors and outdoors • Effective against common pests and fungus • Great for both prevention and treatment • Easy to mix and apply • Brand offers a full plant care line ⚠️ Cons: • None so far — just hoping I don’t need it for a big infestation anytime soon! Overall, this is a fantastic organic option to have on hand for houseplants, gardens, or lawns. A must-have in every plant parent’s toolkit. Another win for my plant addiction 🌿💚

Arbor Organic Insecticide & Fungicide has been an absolute lifesaver for my plants. I was struggling with mold in the soil and an annoying infestation of fungus gnats, and nothing seemed to work long-term—until this. Within a short time of using it, the mold cleared up completely and the fungus gnats became a thing of the past. I love that it’s organic and gentle enough for regular use, but still powerful and effective. My plants look healthier, the soil stays cleaner, and I finally feel like I’m back in control of my indoor garden. If you’re battling mold or gnats, this product is 100% worth it! 🌱✨

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!!

Currently in my first year of raised bed gardening so, naturally, I’ve been freaking out about most bugs and damage to my plants. Was looking for something organic, that works as both a foliar and ground spray, when I stumbled across Arber on Shark Tank. This review is specifically for the insecticide and fungicide combo pack. During the initial setup of a Greenstalk vertical planter, I noticed a hefty amount of aphids. After applying the Arber insecticide nightly, the amount seen on the vertical planter has diminished significantly. The insecticide also seems to be working on my cucurbits and other plants in the raised beds as there’s minimal damage and bad bugs are rarely seen (though I do inject my plants susceptible to vine borers with a healthy dose of BT as well and have co-planted other plants to help ward off bad bugs). The amount of caterpillars and gnats/flies I’ve seen have also diminished. The fungicide seems to be helping other plants as well. Compared to the leaves growing while at the store, any newer growth appears lush and very green. While it may not be a noted use case, I use it as a foliar spray on my citrus plants/trees as well. Both the insecticide and fungicide are easy to mix and I mix in them the same sprayer (which seems to be okay per the instructions). The insecticide isn’t as thick as the fungicide and I’ve found myself with more fungicide remaining in the bottle after all of the insecticide has been used (by about an ounce or two). The fungicide does smell a little worse than the insecticide. Neither smell like chemicals but have that usual natural, organic smell. I’ve noticed no burn damage on the leaves of any of my plants from use. I typically spray in the evenings after the pollinators have stopped flying and the sun has gone down a bit. Plants get a healthy spray, from a one-gallon sprayer, on top and on the underside of the leaves. For good measure I also spray the soil/mulch around the base of the plants and any stalks/stems. One gallon goes a long way in my garden and I usually have extra left over after spraying. I mix, per the instructions, using an old dosing cup marked for the appropriate per-gallon ratio. The cups fit nicely over the tops of the bottles for storage. It’d be helpful if one was packaged with the products (but I understand the added value equals increased production cost). As far as pricing is concerned, I’ve found that there’s about a $10 difference between ordering the two pack off of Amazon and ordering through the Arber website (still the same at the time of writing this). Cheaper via Amazon. As such, I’ll likely always order via Amazon. Shipping through Amazon is likely quicker as well. For now, the Arber insecticide and fungicide seem to be working as they should with nightly application via a one-gallon sprayer. I’m happy with the product and have ordered an additional pack of the insecticide and fungicide as well as have added on their plant food and protectant.

Bought this to use as preventative. I love that it was organic to use it in my house with all my houseplants.The day it arrived, found out I had spider mites! It has worked fantastic with killing them! I’m still planning to use as a preventative. Does have a little smell. But not as bad as some have reported. It’s concentrated you use four little caps per gallon of water.

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.
