Small black flies

Howzit fellow growers.

I just prepped my super soil and covered with a mulch layer for season.

When i lift the mulch layer there are hundreds of tiny black winged insects that look like gnats but smaller.

All my pots are infested with these bastards.

Is it something that i have to worry about or do i just let them be?

I tried Margeret Roberts organic incestide but doesn't seem to help much.

Please advise. Thanks

DE will only really work on soft bodies such as larvae dwelling in the top soil. 

if the plants are still in veg you gona have to combine a contact treatment with preventative measure. fighting a already existing colony and keeping the plant happy and thriving is a big challenge, there is no one and done treatment here, it will be a series of steps. 

I would suggest 50 to 75% (this shit is strong as hell and can easily burn your plants) strength Pyrol treatment, 3 or 4 days later a 50% Neem soil drench (don't want to contaminate your soil and make it uninhabitable for your plant), atleast 7 to 10 days after first Pyrol treatment do a second Pyrol at 50 to 75% again, another 3 or 4 days later the second 50% Neem soil drench. 

repeat this untill you see no more flies. 

if plant is showing signs of being unhappy, dial back on the % of product you spraying and skip a week of treatment to give some recovery time, but not too long, need to stay ontop of those fly fucks.

once you don't see any more activity, continue with IPM, I would suggest keeping a dry layer of DE ontop of the soil, with light 25 to 50% Neem sprays every week untill flower.

      Howdy folks, first post here, been lurking for a bit, not really one for introducing myself and also haven't been on a local grow forum since BelowTheLion had a grow forum...so.....eh...howzit👊.
      Recently run into some issues with root aphids, so thought it appropriate to communicate with local communities in order to see what methods people have used in the past to treat infestations, as well as share my experiences.
      * Currently Day 25 of Flower at posting(11/04/2019)
      Setup:
      Mars Grow Tent(Total Grow Space - 2.4mx1.2mx2m) 1 x Extractor(700m3/hr - 11.67m3/minute) - Negative Pressure 600w HID(Sunmaster - Dual Spectrum [Flowering Period Only]) 2 x 45l D.W.C Reservoirs 2 Plants per res.(125mm Net Pots with Hydrotron/LECA) ScroGged(Utilised Grow Space - 1mx1.4m) Strain:
      4 x Green House Seed Co. A.M.S.(Identical Cuts)  
      Preface:
      For the record, I had some how allowed myself to be fooled by the idea that subterranean pests wouldn't really be a factor in hydroponics, especially Deep Water Culture, but boy was i mistaken, so please, don't fool yourselves with this idea guys.
      If anything, in my resulting opinion, the hydroponic environment can actually be more conducive to certain pests growth when comapred with its media/soil counterparts, however, on the flip side, much like dealing with nutrient burns or P.H. issues, hydroponic systems have a greater potential for fast recover.(*Provided you are able to identify the issue/infestation early enough.)
       
      In hind sight, I can easily say that the first sign of my infestation actually started showing a little over a week ago, however I would only come to realise this 3 days ago.
      It started with me waking up to finding a mass of dead fliers on my tent floor, which I had simply assumed were just miggies trying to get to my light and moved on, however I would soon realise that these were actually the winged adults of an aphid infestation.
      I only realised the true issue when it came to nute change time, which is when I discovered a rather established Root Aphid infestation when going to siphon my reservoirs.
      *This is when Hydrogen Peroxide(H2O2) becomes your next best friend.
      Treatment:
      Day 1: Sprayed with Ludwigs Insect Spray +. Flushed reservoirs with fresh water and tried to physically remove and wash off any visible aphids as much as possible. Filled reservoirs with P.H. balanced water and added 12ml(30% H2O2[Clicks - 30 Vol.]) per resivour. Only water/circulation pump running - aeration turned off to potentially try reduce H2O2 reduction to H2O. Day 2: Sprayed with Ludwigs Insect Spray +. Added 5ml(30% H2O2[Clicks - 30 Vol.]) to each reservoir. Day 3: Flushed reservoirs with fresh water and tried to physically remove and wash off any visible aphid debris as much as possible - can clearly see that the infestation is not thriving like it was. Added normal flowering nute mix Aerators back on(*System to run as normal) I definitely feel that my initial knock of the infestation has been successful, however it is crucial that I ensure that I keep on top of this infestation by inspecting my rootzone multiple times a day when possible as well as spraying Ludwigs Insect Spray + to ensure that any crawling/flying aphids are exterminated and unable to continue their life cycle.(I have had great success with Ludwigs Insect Spray + for canopy/foliage pests).
      If I see any signs of the root aphids getting a grip again,  I will repeat the steps from day 1 and 2(H2O2 Volume to be determined).
      *Yellow fly paper would also be extremely beneficial at reducing winged flier survival success rate
      *It is crucial that anyone reading this post realises that these are my experiences with a Deep Water Culture Hydroponic system, and that if you encounter root aphids in a soil-type medium, H2O2 will destroy any organic organisms in your medium, if at a strong enough concentration, beneficial organism or not. Ensure that you consider this and research accordingly before taking this as word.
      *Please also realise that the effects of root aphids will most likely show as a nutrient deficiency first, unless the rootzone infestation is noticed before hand by the grower.
      Any experiences or input would be much appreciated - substantiated or opinionated <3.

      So I have managed to plants my already germinated seeds in to the open ground after germinating them in doors ina secure environment. 
      Only to find wild cats eating my young growth how do I stop this? 
      All and any advice would be great. 
      Ps I'm not about hurting animals so many not that advice.
