Hello everyone! I'm a new vermicomposter! I have this thing called a Garden Tower 2 which is like a giant planter with a large tube in the middle that runs through it for vermicomposte.

So I've been feeding my worms and having a grand ole time but alas I was hit with a fungus gnat infestation. Now this garden tower 2 is massive. Essentially its four feet tall with the vermicomposte tube running down its full length.

The tube has holes to allow the worms to go in and out of the soil freely but this has led to my gnat problem going well deep. I water it from the top and it soaks all the soil to the bottom.

I am not sure how to handle my newest infestation here. I've dusted it with DE but the soil is always at least mildly damp so idk if that will work. I've done the mosquito bites dunk but it was taking too long as this was originally in my house.

For now, I've moved it outside and my gnat problem is pretty much over. I'm using traps and sprays to kill the stragglers. They have no food indoors and I'm keeping my house spotless until the last stragglers are dead or gone.

BUT! What do I do about my remaining indoor plants who unfortunately got gnats? I did a hydro peroxide mix for the potted plants that don't have worms in them and it seemed to help but the adults suck. I've been spraying them(cautiously around plants) and they're fucking off but what an adventure.

TLDR: How to get rid of gnats in soil that's never fully dry(the inner soil is always slightly moist) and also has worms.

Also how to quickly kill the adults since I think I can kill the babys pretty easy.
