    Then somehow you did it wrong. The dunks, crumbled on the soil surface as the op said, and one floating in the water you use to water your plants, WORKS GREAT. And since there will always be some still flying (as it only kills the larvae), a sticky-trap or two IN ADDITION TO THE DUNK TREATMENT is a good plan for a faster kill rate.

    All houseplants must get the same treatment too !

        IDK.. I made the switch from Hydro back to soil & I have never had such a hard time w/ pests.. mostly these fuckers!
        Is it safe to say it's easier to rid them from hydro units than soil?
        I'm considering goin back ,after 10 yrs ,I thought I'd give the dirt a try Stupid me :(
        ....peace to all beings

                      Sorry Lola, but dunks don't work. They only slow down the infestation. The time wasted messing around with dunks just prolongs the problem and reduces yield. Same thing with Gnatrol. You end up with a resistant gnat thats even harder to eradicate. What worked best for me was to spray the rootball directly with pyrethium (FoxFarm's Bug Be Gone). The plant pulls it up thru the roots for a systemic effect.

                      Death to the f'ing gnat hord!!

                      Seed Buyers Beware! Don't waste your money on hype. If you have to buy multiple seed packs to find that "keeper", you're getting ripped off. Every female in a pack of seeds should be a keeper! We've been led to believe that lots of variation in a cross is a good thing, because some vendors would rather you buy several packs of their gear, instead of them actually doing the selections to fix that nag champa or golden clit trait themselves. For hobby growers, pheno hunting is fun. But mono-croppers who grow to pay the bills prefer a consistent product that regularly delivers the desired trait package.

                          I got the diamaceous earth at home depot. A little goes along way.
                          I have also used is on top of the soil. You just got to watch it packin down the soil.

                            BTI/Gnatrol has a negative effect on yield?

                                The Dunks break the breeding cycle by killing off the grubs in the roots.

                                Adults can be zapped with a little pyrethrin spray in the air. Also yellow sticky fly paper is good to catch adults.

                                But ONLY using dunks, my grow was fungus gnat free in 3-4 weeks. AND it has stayed FREE of gnats for a year, by adding a little dunk to new soil as it is brought in.

                                Yellow sticky fly papers are so cheap and so effective. You should have a couple hanging in your growroom at all times! That way you can see what's coming in to your growroom and respond accordingly. Great thread LolaGal.
                                Stay safe
