Bonide Systemic Houseplant Insect Control, 8 oz Ready-to-Use Granules for Indoors and Outdoors, Protects Plants from Insects

I wanted to give this product a chance to work before posting a review and here it goes. I love plants and since repotting several of them at work, my office became unbearable because fungi gnats were a constant nuisance where they bothered and swarmed everything and everyone who came within a 10 ft radius of my office. I tried everything such as a peroxide solution, sand and sticky traps but those worked for a short while then the gnats were back. I even bought a bug light and that worked but it was an endless cycle of insanity so I gave this product a try. I brought this stuff with me to work on a Tuesday, sprinkled it on the soil, watered each plant thoroughly and it’s now Thursday and not one single gnat has bothered me. I still have the sticky traps for any that may wander in from other offices but this stuff is fantastic! There’s no scent so it’s office safe, very effective in that it seemingly worked overnight to solve my problem, didn’t require mixing and coned in a handy bottle that allows you to either shake or pour the granules. I used disposable gloves when handling it because I’m paranoid but that’s a small thing compared to the peace of being able to enjoy my plants in peace. I’m keeping a bottle of this stuff in my desk drawer and will spread the word around the office. THIS STUFF REALLY WORKS! The pictures show how horrible the problem was before application. Now there aren’t any gnats!

Helped me get rid of thrips!! This product really works. Unfortunately it doesn't help spider mites. But it's great for other pests (like thrips). Easy to mix into top layer of soil and water in. I like that you only have to apply every 8 weeks

This product works really well, but the container only comes about 1/3 full.

For years I had tried everything to get rid of small fungus gnats in my plants. Nothing worked. Just one treatment of this stuff got rid of them all!! I know this because I changed out the sticky bug tape when I applied the Bonide and a week later there are no bugs on the tape.

Not sure it's working. Guess it might take awhile. Purchased 2X. A suggestion would be a different container. I get that the amount is what is in it but it's 1/2 full. It's difficult to use an instrument ( plastic spoon) to get to the product. I scratch my fingers on the opening. I have purchased 2X and am hoping it works. Price is fine as everything has a price. Maybe a smaller container with a larger opening.

I had problems with my plants...hundreds of gnats all over for months. Tried everything i looked up. At my wits end, I ordered this and mixed into all infected plants and surprise, it worked!! Within 2 weeks I was gnat free but definitely saw results much sooner. I'm going to mix into all of my new plants and repotted plants this spring. It really works!

UPDATE 2017-05-08 I got rid of all my houseplants, mainly because of the fungus gnats. Also because I'm trying to simplify my life. This Bonide product did work to greatly reduce the gnats in our home. However we never completely got rid of them. I am concerned about this product because the active ingredient is imidacloprid, which is strongly suspected of being harmful to bees. If I overwintered certain flowering plants indoors, like begonias, and used this product on the soil, then put the plants outdoors, perhaps the flowers could hurt bees. The product is systemic, so even though you apply it to the soil, it goes into the plant's stem, leaves, and flowers. So I lowered my rating to 3 stars. UPDATE 2016-01-10 It's been about a week since I finished treating all our houseplants. We're seeing a BIG improvement!!! YAY!! We've only seen about two flies in six days. Before, we'd see many flies each day, some flying in our faces, some attracted to what we're eating, or hovering around our computer screen. I think the Bonide product is the main thing that helped - I hope it's not premature to say - solve the problem! 2016-01-03 So far I like it a lot. I've been treating our houseplants because we have a fungus gnat problem. I like that the product is easy to handle. The consistency is like pepper. First I loosen the soil of the houseplant with a very small rake or craft stick. Then I insert a plastic, long iced-tea spoon, dedicated for this purpose (NOT to be used later for iced tea) into the slot at the top of the Bonide product. I take spoonsful of the product and sprinkle it on the soil of the house plant. The product stays in the spoon until I sprinkle it on the soil. Next I use a craft stick to work the product into the soil. Then, I water the plant. I'm being very careful with this since it is an insecticide. I didn't want to use an insecticide, but I've tried the less aggressive ways to fight these pests and we still have them. Here are a couple of other tips for fighting fungus gnats, which I think do help: You can get Hafer yellow sticky squares on Amazon; you can cut these in half lengthwise and stick them on craft sticks. Then you can stick the craft sticks into the plant soil. Also, be sure your houseplants have good drainage. (I don't use moisture control potting soil any more. It's important to LET THE SOIL DRY between waterings; moisture control potting soil is made to retain moisture which is NOT GOOD. I mix perlite in my NON-moisture controlled potting soil for better drainage.) The reason to let the soil dry between waterings is that the gnats reproduce in moist soil and they die or go into suspended animation if the soil becomes dry. In fact the gnats spend most of their lives - about two weeks plus 5 days as larvae and pupae - in the soil; they are in the adult stage flying around for only about 5 days. During which time they lay 300 eggs in the plant soil, and the process begins all over again. There is a lot of information on the internet about fungus gnats. I plan to write an update about a week after I finish treating the plants. Hopefully this will do the trick!
