Will this kill fungus gnats in my potted herbs?

Yes it will but not instantly. It takes approx. 1-3 days (give or take) for the bug/fly to dry out, but it will happen and you will be very pleased with the end result.

BTW Adam, because you have a *fungus* gnat issue, you should probably water your herbs from the bottom until the situation clears itself up otherwise you will continue to have the issue. What part of the country do you live to have a fungus situation like that? Or maybe you're watering too much? Anywho, Put some plastic coasters under your plants (if they are in pots) or switch to a soaker line (if in a garden) to avoid the over watering gnats issue. When applying the DE use this: Pest Pistol Mini Duster. But remember, each time your DE gets wet, you will need to re-apply it that's why I suggested the two versions of watering.

Yes, it will. It is designed to kill just about any living tree, shrub or plant. Be careful.

My understanding is yes, it is applied to the soil and supposedly "Natural", hence "Gnatrol". I did not use it on herbs or vegetables, I used it on house plants.

Yes, and no! As Hersom states below, it will work if the gnat physically touches the diatomaceous earth powder. Therefore, if the gnat walks on the diatomaceous earth powder, it will kill them. My suggestion for gnats on houseplants- depending on the severity: 1) some gnats may be there due to wet conditions including poor drainage. See if you can withhold watering for a couple of days so that things can dry out a bit. 2) spread a layer of diatomaceous earth on the top of the soil. It does not need to be too thick. If you can get a layer on top of the plant soil and then avoid watering for a couple of days - that can help. 3) Check into the yellow sticky cards/paper and hang them around. I think this will work:

I checked with my husband and he said "yes it does inhibit new growth as well kill current suckers". I know this is the only product that works for us and it is far more expensive at the local nursery. Hope this is helpful to you.

I use mine dry, just sprinkle around the entire top of the soil and water in. This is the only thing that I have found that gets rid of the pesky gnats. I tried all the natural options, repotting and other chemical options and they didn't work. I have heard that the gnats lay their eggs on the roots of the plant. I am not sure how often to use. The bugs are usually gone after one application. If you still see some bugs in a couple of weeks, I would reapply.

Though it is "organic" it also may cause other problems. There is some concern that this may also kill off helpful pollinator insects like honey bees. Fungus gnats are a product of overwatering that feed on the fungus that forms near the surface of the soil. You might also try watering less and also putting some kind of topsoil, sand, or glass that they won't like. If these are indoor plants, I would spray the spinosad on the soil because that's where the fungus grows and is what fungus gnats feed on. I'm imagining that these are indoor plants because there wouldn't be any other reason to car about fungus gnats. Good luck.

I honestly don't know. It works well for my flowers, but I have no vegs/herbs to try it on. Depending on what you are trying to kill, and if you want to stick to household items, you could try a heavy mixture of liquid dish soap and water in a mist spray bottle. I know this works well for ants (it plugs their trachea tubes - they cannot breath). Sorry - wish I could help.

I don't know. I bought it to use on caterpillars that were infesting my Texas Laurel. It does a good job of keeping them under control. I would suggest you Google what kills gnats. I have an idea this won't do the trick.

Hmmm...It took about a week before I started to see a reduction (since the Gnatrol doesn't kill the adult fungus gnats). I used 3 teaspoons per gallon because I had a heavy infestation. I then let the plants dry out before I watered again (little more than a week - but you might have warmer conditions than I do). I tried EVERYTHING, and Gnatrol (plus correct watering methods) is the best method. Before I ordered the Gnatrol, I changed out the potting soil I had just potted my plants in because I used Miracle Gro's moisture control potting mix, and I realized it was holding a lot of moisture which is a breeding ground for gnats. I switched it out for the regular Miracle Gro mix that can almost dry out between waterings. Make sure you're letting the top inch or two of the soil dry out before you water again. There must have been a gnat or two that survived the first 2 doses, because I was busy and skipped the third time and I saw a flare up, so I'm back to using it again for a few more times.

It will, but you will probably need to reapply two or three times to really kill the roots. I would suggest waiting until you see new growth before applying the second (and third) time. The shoots will die off, but this won't kill the roots immediately.

Not sure if it works on gnats as it is a fungicide. Has a pretty funky oder so use indoors is not a good idea.

I have used this product for two years and have not had the lawn fungus come back in that time. I do have tall fescue and yes it does work, Mmy neighbors are still having problems with their lawns and have asked me what I have been using.

I don't know about gnats, I never tried it on them. I mainly used this product on my garden to kill aphids, mites and cabbage looper moths. I think it would work on them as it seems to eliminate many of the same type of insects.

This product will kill any kind of vegetation you spray. However, that is only if you directly spray them. Spraying pest around them and spraying the soil will have no effect on these plants. It Only kills what is directly sprayed.

A mixture of vinegar, salt and dishsoap should kill dandelions, so I would expect that this would as well. Don't get it on your skin.

I bought this product to use on my basil, which had downy mildew, and my houseplant, which have an assortment of bugs and mold....I found it worked well on my lemon tree, which had mold, too, but you will need to treat it routinely. See direction on product label.
