I agee.The DE kills the larvae when they try to leave the soil by dehydrating them. No fly away and no digging into the soil. Done.
FWIW: Diatomaceous earth didn't do anything for me. I'm considering adding some to my soil for DE's mineral content. But, it didn't do anything to the gnats.Sprinkle the DE on top of your grow medium. Reapply to surface after each watering, as DE works best when dry.
Sorry bro, no chemicals! There are natural ways that work better. Ie. just let the soil dry out and use DE.Try gnatnix the few times I've had gnats it worked great 2 days after use and there all gone https://www.1000bulbs.com/product/112830/GROW-GPGC33CF.html?utm_source=SmartFeedGoogleBase&utm_medium=Shopping&utm_term=GROW-GPGC33CF&utm_content=Growstone&utm_campaign=SmartFeedGoogleBaseShopping&gclid=COjj38_y1cQCFQGNaQod5HQA9A
