Review: Got fungus gnats? Use the insecticide with the fungicide! - 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!!
Review: Amazing!! - 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 desertcart, 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.

## Features

- Stop infestations fast: eliminates fungus gnats, aphids, whiteflies, mealybugs and spider mites on contact, then protects leaves so plants bounce back greener and stronger. Use at first signs of pests on houseplants or garden beds.
- Powered by organic biologicals in a true liquid concentrate, it penetrates foliage and soil to disrupt pest life cycles while supporting a balanced microbiome—so roots thrive as populations decline without harsh synthetic residues.
- Customizable dilution for seedlings, herbs, roses, and shrubs—use lighter mixes for weekly maintenance or stronger ratios for flare-ups. Ideal before moving plants indoors, after repotting, and when quarantining new nursery arrivals.
- Made for organic gardening and everyday homes—low-odor, dye-free, and gentle on people, pets, and pollinators when used as directed. Works indoors or outdoors on pots, raised beds, edible gardens, and greenhouse collections.
- Simple to mix, easier to trust: add to water, shake, and spray leaves and soil until lightly wet. Use between waterings, before big blooms or harvests, and after nursery runs to keep your plant collection vibrant, resilient, and pest-free.

### ⭐⭐⭐⭐ Worked Great! But ALL THESE SPOTS??
*by L***Y on October 14, 2023*

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?
