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: No More Gnats! - We were dealing with fungus gnats in one of our plants, and this has really helped keep them under control. We removed the top couple inches of soil, replaced it with sand and small rocks, and started using this product when we water (which isn’t very often). Since then, the gnats have stayed at bay. We did spot one gnat at one point, used this again right away, and didn’t see any more after that. We’re now continuing to use it as part of our regular maintenance, and it’s been working well.

## 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.

### ⭐⭐⭐⭐⭐ First time plant parents friend to combat gnats!
*by C***I on June 16, 2025*

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!
