Try turning fan on pots, they dont fly the best, you can disrupt their cycle in many ways. Topdressing, spraying etc.

Neem foliar, 5ml neem oil, 2 mil of soap, warmish water, shake well as you need the neem to disperse, spray on plants at lights out.
Will this kill any larvae in the soil? And what kind of soap?
Thank you!
Thank you I've put the fan directly on the soil now!

Dawn, the blue one. I swear by it.
Do you have a link? I'm in UK and can't seem to work out where to get these! Thank you!

Its much cheaper to buy neem oil on eBay UK. Then mix as I've said, you want liquid soap but you don't want anti bacterial, I watched a video said to put water in my worm bin to get juice from worm castings, I ended up with very moist soil and gnats were everywhere, I sprayed Neem oil foliar all over plants, used sticky traps too, and removed bin because weather is warmer so can be okay outside. But Neem does the job, don't over think it, buy neem oil and liquid soap.

Raising my pots and cutting back on watering is all I've ever had to do to combat gnats.

Usually you can just adjust your watering practices or some fans to fix this...but if you have a shit ton, then you will need to treat it. Can keep using the sticky pads to kill the adults, and water in nematodes into the soil. They will take care of the larvae. If you still have issues, water the other half of the nematode pack in a week later.

I had a horrible infestation during my last grow and bought nematodes, but I cut back my water and they all went away before I needed to use them. They can't hurt, but I don't think they're really necessary.
Also blasting a fabric pot with a fan can cause molds and issues with your roots. If you're going to do it, try to to keep the airflow just above the pots or use an oscillating fan set to low.

Yes...I should have been more clear. My oscillating fan is directed at the tops of the pots and the underside of the canopy to move air through my mainline setup. That is how I got rid of gnats as well.

DE works as topdress or spray but needs rinsing at later date if used as spray..
Fungus Gnats
Yellow sticky tapes, and, fresh good quality duct tape, or the stickyest tape, maybe tuck tape red. Roll a bunch of that and place it over the medium, over the whole hole. Pointing up and down. It will be covered in no time. You can also change your air exhaust hose ls around, and suck the...

If you want to get shot of fungus gnats all you need to do is use sticky traps and let the pot dry out as much as possible between waterings. I have tried all sorts to get rid of them and letting the surface of the pot dry out was the best solution, the larvae thrive in moist soil.
