Tiny White Worms in Soil Mixture +REP

Ok, so I have this really bad infestation in the buckets of some of my 1 month old plants. I bought some top soil that was contaminated with fruit flies, or fungus gnats or what have you...

I had to store it and mix it in the grow room for security reasons. At first there were only a couple little flies here or there that I could kill and thought they would go away...Now there are a lot and some patches of soil on the top of the buckets are infested with tiny white worms, which I assume them to be the fly larvae...

My medium is a roughly 2/5 MG Organic potting mix, 2/5 MG Perlite, & 1/5 topsoil...

Is there something tried thats proven to rid my garden of these pests? +REP

get yourself some indoor garden insectacide...if that doesnt work, toss the plants and go soiless mix next time...

that's the risk you take by buying topsoil from a farm...there's weed (not MJ) seed, insects, bacteria, fungus...all the nasty stuff that nature can throw at you...when you use reg topsoil...always go with a bagsoil...its heat treated to prevent the forementioned pests...

thanks, i'm going to need to buy something to treat the soil to kill them... and the top soil I bought is the scotts stuff in the bag from Home Depot... (which I am very unhappy with btw... probly going soilless next time)

i havent been happy with past MG soil or any potting soil mix from past grows...i go soiless unless its in mother earth

sprinkle diatomascaeous (sp) earth on top of the soil and let the medium dry out a little more between waterings. You'd be amazed at how well just cutting back the watering will help.

great, thanks for the advice! I'm sure a combination of a few things will help the most...
