How can I kill gnats in stored coco?

I’m getting ready to stored used coco from a harvest that I struggled with fungus gnats with.
I still have the root ball in containers so I can flush them with something or put something in storage bin with them.
I thought about putting storage bin then adding something so in a few months gnats are killed.
I have azmax and thought water down coco using it then store coco in bin.
Neem doesn’t always kill gnats right away but that’s when plants are growing and neem is rinsed out during feedings.
If I water down coco with dosage of neem then store it away will that kill the eggs and flyers?

killing gnats

I believe Joker means 5% H2O2, though 3% in a 1 part H2O2 mixed with 3 parts H2O will work fine in killing gnats. However, I would never recommend reusing gnat infested medium. Money saved does not justify the headaches nor the potential for reduced yields IMJ.

I buy the 35% food grade dilute it to 3% then down to .5%.

the 3% in the store has a carcinogenic stabilizer in it. STAY AWAY FROM IT!!!

when you do this you have to repopulate beneficial fungi n bacteria....great white myco works very well. Cover with a thrips proof screen.. .0055 X .0055 mesh screen works very well..

Never done this before but will be soon cause my soil needs the same thing done to it.

This is the idea i came up. So ill be trying it out too....lol...ill post my outcome....that could be a few months from now though....

if you've got fungus gnats, it would probably be a good idea to change up your growing in some way to stop the rotten roots. THAT is what they live on, or other rotting vegetation somewhere in the house. When I make lemonade, the rinds ALWAYS draw in fungus gnats. The screen suggestion is a good one IMO, but there is still a problem (that can create other, worse ones) if it's originating from the grow.

What is the specific stabilizer you're talking about, and what reason do you have to believe it carcinogenic? I spent a half hour researching this this morning and couldn't find anything.

acetanilide and theres others as well....h202 can bring other chemicals into cells that are carcinogenic....theres chelates and sequestrants as well....google that you should get all the info about it

Google carcinogenic stabilizer in hydrogen peroxide...i got that info from doing that

I think another problem was I wasn’t washing coco after blocks expanded.
I just mixed up a low ec nutrient mix and let block soak it up and expand.
I started seeing a mud like paste towards the bottom of what I soaked blocks in.

Washing even the best of coco blocks has become a norm.
