disease-pests Gnats

[RoyalPepperlegion]

I have 2 indoor pepper plants I potted up and I had soaked the soil with boiling water before transplanting, I still have a bunch of the gnats coming out of the soil. I have tried the yellow traps hanging, on the edge and over the dirt, as well as mosquito bits and they are still there. I have a fan on them every other day. What else should I use? Neem oil, Spinosad?

One of the options that worked for me was a 1:4 hydrogen peroxide to water solution that nuked the nasty larvae in the soil. After that inoculate with beneficial nematodes to keep the soil free to larvae.

Using this Biofungicide for the last 4 years, we have had 0 fungus gnats.
Other than moving to Coco Coir pellets this is the only other change we made.
We did swap out our old Fluorescent lights for Modern LED Grow lights, I doubt that would have made a difference.

The way we use this product, soak pellets, mist & water seedlings continue to use in every watering. Once inground
I use it in the 7 to 10 day sprays & in the hose end feeder for foliar feeding.

I got some spinosad but if that doesn't work ill try the hydrogen peroxide. Not sure if I can get nematodes here.

If you can get your hands on the nematodes, it's your best bet!

For killing what is already there I give a +1 to bleach. As for prevention, I have found topping my pots off with sand to be completely effective. They don't seem to like laying their eggs in it. I normally aim for around 2cm of sand. Note this is for my indoor established plants, I don't do this for my seedlings and young plants, I normally just spray those with something like neem.

I have read Dr. Bonners soap diluted will kill fungus gnats. I use Captain Jacks Neem Max.
