I recall reading that when the grubs emerged as adults they would lacerate and die, yeah. So after one cycle there would be no gnats. If DE does kill gnats.

Are fungus gnats "bad" if not eating your plants?

i wouldnt treat these fungus gnats lightly... i had never have encountered them till last grow.. started seeing them in late veg - it got worse till harvest.. im sure i lost about a thrid of yield to them... about 10 plants died and a couple were stunted... treat them asap!!

The only good fungus gnat is a dead fungus gnat...
Besides, they are known vectors for TMV.

I tried a generous layer of DE on top of my mulch. Within hours it seemed like they were nearly knocked out, it was amazing. The mulch keeps the DE on top of it dry, so I figured I would be killing all the emerging adults as well as the adults crawling through the mulch to get to the soil.
They're back. Now, they just hang out near the bottoms of the pots. It seems that the emerging adults and egg layers just go in and out through the holes in the pots. Really no way to keep DE dry down there.
Anybody know if BT kills nematodes?

DE helps, but it's kind of messy and increases algae. Try the BTI in the link I provided above. It's so cheap and safe, you can just run it all the time.

they seem more forgiving in soilk/coco bt when i was running dwc's some gnats in the room were a sure sign i had pythium somewhere. those fukers chew holes in good roots, and their filthy mouths spread infection everywhere.
I tried leaving little toothbrshes, and listerene for the wee fuckers, but they never used em. prolly cuz they dont read so well, and the signs i let up were in english.
imidacloprid (merit/bayeradvanced etc...) , applied one time during veg. kills em all, breaks the cycle....also gets RootAphids whitefly even the lowly and mostly benign springtail.
its systemic, so i never use it within 90 days of my harvest date, and at this point in my control regimen, i only use it every other growing cycle.
if in flowering then the Bt i recommend is the mosquito dunk "crumbles". the finley powdered bt "(gnatrol) has a good knock down but quickly dissipates, whereas the crumbles are sustained release for weeks.

nematodes every 2 weeks. I use the double death mix. I got them originally to rid myself of thrips but I got rid of the gnats as a bonus.

I like to do this every three months as a preventative now. Its like having your own soil army. peace leaf

gnats are nothing to laugh at. i had a couple at first and i thought, nothing seems to be effected i guess i will just kill the ones i can see. a week later and there are 3x as many flying around now. kill those with a vacuum cleaner and put up sticky strip. a week later they are all over the place, sticky strip covered in little bugs, and now when i water my plants i see some fly out of the soil. not to mention they fly onto the buds, get stuck and then die. who wants to smoke dead gnats?
so far ive been using natural remedies of not watering as much, to let the soil dry, and i just recently topped my plants with some southern red dirt i brought back from alabammy last time i was down there. i noticed the plants i had in the red dirt were the only plants in my whole house with no gnats. muts be too thick for the to lay eggs in or whatever. i added like a half inch of that to the pots i could and so far it seems they cannot lay in those pots. it doesn't keep the top dry, not at all in fact it pulls moisture from below to the top and makes a fine silty muddy layer which dries hard.
trust and believe everything everyone said about the damage in this thread. you won't notice it at first but after a while you will see that the plants aren't doing much growing and they aren't taking up water. all those fungus gnat larvae decimating your root system.

best solution i have found is 1 inch layer of sand over top of medium. then bottom water.

Not that much of an issue. Mostly with young seedlings and clones. They love to eat the fine roots. Throw up some yellow sticky paper and about an inch of sand on top of your plants(if soil) You can also use dm earth
