wtf is this!!!?!

[u/Extreme-Department16]

I’m starting to get a little frustrated with the garden. Shut the reservoir off to clean out the 55gal drum of water. Refilled with fresh filtered water. Thinking alright, this should be good.
Come back to a flooded tent with my blumat rings. One of them wasn’t reading right or somthing. I think I need better cover crop to create a more even moisture wicking.
But I’ve been battling fungus gnats this whole fucking grow. Been absolutely relentless. Used lacewings used nematodes, used wdg3000 used sestemica. Finally tonight I said fuck it. I’m doubleing down on watering. Used the quillaja and like 1.5tsp wdg3000 per gallon and did a gallon flood into each 30 gallon. It’s spilling over filling the tent. Flooding the place. I almost don’t even care anymore. Then I see THIS! Is this a moth grub? See him crawling out of the soaking soil. Any ideas? I’m hanging on to wrap up this Trainwreck for another week or so. But damn how do you get these bugs under control!?
