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!!

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.

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 fairly gentle on my plants and I've had no issues with any leaf burn. I've used it to get rid of spider mites mostly, though the mites still seem to come back a month later. It's not that great on fungus gnats, mosquito bits work better than anything else on the market. Unfortunately I had to stop using it as a spray. Even in distilled water, it goes "fungal" and grows mold or some sort of scum which turns into chunks, if you leave it for more than a week in the bottle. Even my watering cans end up with this weird scum. This will then clog up a sprayer. (I ruined a really good continuous mister.) Now I use a different product to mix as a spray and this product to water with so that you get the soil pets and the leaf pests. The only other alternative would be that you have to mix, spray and then pour back into the watering can. Dropped off a star for that.

It says one of the pests it’s for is fungus gnats. Fungus gnats see this and think they are getting a treat. I literally dose them, see them get stuck to the floor from the amount of spraying and then see them get up a few minutes later and then continue about their business. I’ve seen no decline in the population, I’ve actually seen an increase even though I’m using exactly as instructed in both spray form and soil drench. Mosquito bits can actually zero out fungus gnats, I don’t understand why this can’t even remotely remove the smallest fraction possible. If it’s not getting a pest I can see and it’s labeled to target, how can I trust is doing anything for microscopic pests it also says it’s for?

Can’t wait to finally get rid of the spider mites that came with an order of dirt for my greenhouse beds! I’ve tried Everything else! I will report back!

It's not killing my affids
