What worked for me:
- 1x voile-style net curtain (I used this from Ikea)
- 1x framework (I used an old laundry basket like this one that i happened to have lying around broken)
- 1x UV insect trap (like this one from Amazon)
- eleventybillion yellow sticky traps (per salad-cunt's suggestion)
Methodology:
- Put net curtain over framework
- Put plant inside framework+net curtain bodge
- Put sticky yellow traps around plant, in the soil
- Put UV trap inside net curtain body, next to the plant, to attract wily gnats that escape your yellow sticky traps
- Do not water plants, even if you're worried about them drying out. Dry soil means adults can't lay new eggs
- Leave this setup in place 24/7 until every one of those little motherfuckers has died
Took me about 3 weeks to get rid of them all, IIRC. I only had one infested plant, and it was a drought-tolerant one, so YMMV on feasibility.

Fungus gnats and how to get rid of them, talk to me.
Currently keeping them at bay with yellow traps although had to get rid of 3 Chinese money plants as they were beyond. Thinking of attaking them with Neem oil while covering the soil in the pots with a few cm of sand.
