A late update:
I made homemade compost over the winter and about 4-5 months in I stopped turning it. By spring, it was absolutely infested with fungus gnats. I stupidly decided to spread it across my plot and, well, I had outdoor fungus gnats in my garden, lol. I purchased 30million nematodes from amazon, and threw each sponge piece into a 5 gallon bucket, mixed it up and spread it around. It took about 1-2 weeks but they disappeared and are now all gone. They were more expensive but damn, they work better than MDs. Maybe try that if you're experiencing medium-heavy infestations.
Peace!
