    I had fungus gnats on a house plant a while back, the soil came with them. Honestly they didn't give two shit's about the diatomaceous earth. I finally used some harsh chemicals that you don't want on your weed. I would like to know what can be used for future reference.

    Ive have used gnat nix in addition to neem and peppermint soap spray weekly just on the top of the soil and I havent had any bug issues. Now I do grow within a pretty contained area but still bugs are bugs and they will find your babies. But I have not had any issues with pests while using gnat nix along with neem and peppermint soap spray. and of course a nice breeze on the plants and great air circulation and keeping the grow space very clean...

    It took a few weeks but they are gone
    I used mosquito dunks, neem oil spray, top dressed with neem seed meal, yellow sticky traps, Diatomaceous earth and nematodes.
    I think I killed them all.
    I still do preventive measures. I think you need to do a combo of everything or just nuke your plants with poison.

    I finally found the answer last year. amazon sells microbe lift mosquito control, its biologic safe and frikken works. I put a drop in a gallon of water and apply a splash at ever watering =they've been gone since last year. It also rid my garden of occasional thrips.

    a real no brainer just do it. 20 bucks treats like 5000 gallons of water.

    Applying Azomite definately hurt the population. The sticky traps held them at bay.

    I think this will be the finishing blow. A layer of Gnat Nix at 16oz cup full per 1 Tbsp of Diatomaceous Earth. Added a bit of water and mixed it well. Coated the media surface.
