will mycelium help controll fungus gnat eggs in soil?

since no one knew weather mesquiteo dunks, I guess the proffered method for controlling these things, around these forums, would harm mycelium. Wondering if mycelium will sniff out or help control fungus gnat growth. I have a screened in patio and LOTS of fungus gnats on all of my vegetables and fruits and I need to figure out how to control these suckers but i want to grow mycelium in the soil to help the plants grow bigger in their limited amount of space

fly paper did the trick for me...it's a pain in the ass..but the end result is that no one eats your plants from the roots up...or sucks the seedlings dry (damn gnats!)
it depends on the kind of mycelium...and i can't help on this one...sorry

also one thing i noticed with my plants...i've been adding oxygen tablets for fish tanks to the water i feed them (don't ask why -.- ) and apparently gnats don't like it...dunno how much of this is true...it's just that usually cannabis is a gnat magnet and for some reason right now i don't even see the larvae crawling in my pots...

1) BRIGHT LEMON YELLOW STICKY TRAPS (kinda yellow, orange, blue etc,... DO NOT WORK)
2) at LEAST 1" of FINE SUGAR BEACH SAND on all exposed soil surfaces (perlite, coarse sand, sticks etc,...DO NOT WORK) 2" is better
3) GNATROL in the plants water every other watering for a month

4) stop buying soil that's been left outside for months at a time

do the first 3 things for 2 months and you wont have a single gnat
do the last thing, and you won't get them AGAIN.

I learned this from 6 months of hell trying to rid my tiny studio apt of one of the worst gnat infestations in recorded history.

you can't get rid of gnats with just ONE thing, their life cycle is just too short, and they breed heavily under optimum conditions, you need mechanical traps, moisture barriers, and a organic pesticide, and you need to be diligent about it for a couple of months if you want them GONE.

also I just re-read your post and saw that you have a mycelial culture in your soil?,,....gnats are FUNGUS GNATS, they eat fungus, and suck the moisture from the fungus, because a fungus is ALWAYS WET,...so in a sense, you are FEEDING the gnats with your choice of growing method,...........if you get RID of the gnats first, THEN you can restart your mycelium technique,.....but for now, I wouldn't worry about anything but getting the gnat population under control, and that's going to involve getting that medium drier, and dry medium, and healthy fungal cultures aren't usually used in the same sentence

I broke up a bunch of mosquito dunks and mixed them right with my soil when I mixed it up. About a half tablespoon per gallon, which is way overkill.

The soil I didnt use still in the tub, has mycellium showing on the top, and no fungus gnats either and I had quite an infestation. So I conclude the dunks are safe for that.

The only thing the bacteria from the dunks kill are larvae... mosquito larvae, gnat larvae....

how much mesquito dunk is needed per 3 gallon pot? what method do you use for introducing it to the soil.
 
Diometrius (I know it's mispelled) Earth will take care of them fuckers and it won't hurt your plant. Gnat hatch in your soild and the DE acts like glass and they cannot get thru it. You can get it at any gardening store and it's not too expensive.
