Root Aphids, Fungus Gnats, and other fun bugs (ID PICS)

Video shows the big fungus gnat larvae squirming around and the 3 tiny ones fighting over scraps at the bottom of the tray in collected runoff.
You may notice a little white guy wiggling back and forth right above/over top the larvae.
It's not chewing on the larvae. Its actually at surface and would be the springtail. Only thing I can think it is due to its behavior and description as well as size and appearance. They are ghost white and look like they have little antenna on their heads.View attachment 856684
That's for sure a springtail. I'm sure you know this but for others reading, they're harmless.

Those damn fungus gnats are mostly just a nuisance too. I've found them to be pretty much impossible to get rid of once you have them. Imid is about the only thing that will totally wipe them out but I would never recommend using it just for fungus gnats. Better off just putting a ton of sticky traps over the soil.

Yes, I only just found out what the springtail were a few days ago.
Good to know I've got at least somethin good going on down under.

Only this last while I've checked the runoff for things besides PPM and PH.
Was a bit of a shock at first seeing them squiggly guys down there, but really cool as well in being able to indentify the pesky things in the runoff.
Yellow sticky traps, as you say, all over to catch the flys and stop them landing and popping out hundreds more of themselves. They can get ahead of one pretty quick.
Good airflow right at the base of the plants really seems to keep them at bay as the gnats cant fight the wind to get to damp soil and start multiplying themselves.
A good breeze also helps to dry the top layer of soil off faster, thus less inviting for gnats to nest down.
I also placed some slices of potatoe at the soil surface, nestled in maybe half an inch or so which attracted the larvae to it. Next day turn it over and you will capture a decent amount. Then just toss the potatoe larvae and all.

i found some wormy type bugs in the first couple inches of my soil, i believe it is fungus gnat larvare.
i have some organic pesticides at my disposal.
i have microbe lift, botanigard es, pyrethrum, spinosad and sticky cards.
which one do i use for these larvae?
i have only seen one flying fungus gnat so far, but have seen at least 4-5 larvae.
i sprinkled some DE on the topsoil, not sure how much it will work, but i put one of the larvae on top of a chunk of it and it squirmed alot and then seemed to stop moving so i dont know if it “cut” the larvae up.
any help would be great thanks

What stage are your plants in? I battled FG's for almost 2 years straight in a perpetual grow. Tried Neem oil, spinosad drenches, Diatomaceous earth, yellow sticky traps, rice hulls, sand, hydrogen peroxide... but what eventually killed them was two applications of Merit 75 in pre-veg. Nuked everything in the room including the FG's, Although I used it mainly for root aphids I had at the time.

My takeaway is nothing worked for me on those sneaky persistent bastards besides merit. That said, they also didnt do a lot of damage either. Mainly just annoying. I wouldn't use merit just for FG's. Just rice hulls and sticky traps is enough to keep the numbers down. The annoying part is you have to keep scoping them to make sure they arent winged root aphids.

Grateful to see this thread is still active as it has some of the cleanest photos of pests on google!

I've been trying to deal with a possible pest/beneficial and I'm still not sure what I have after going through this thread (as well as 7 weeks of internet searches and a few visits to the local hydro. I know I have fungus gnats but can't determine if these other things are beneficial or not. The local store said they looked like root aphids, but they look closer to mites to me, they just seem so much more hairy than most of the pics I can find and I'm not positive on the leg count although it looks like 8 there are smaller ones of the same shape.

I initially discovered them on a leaf in mid veg, but after an initial treatment of Nuke Em, I never saw them on the plant parts again. I also introduced Z7 to my regular watering and from this point they were discovered on the outside of my grow pots and seem to collect in the water trays underneath which is the source of the pictures. I've also used SNS 203 and Monterey Takedown Garden Spray all with seemingly instant kill results with the population being slowed down but not eliminated I believe due to them being in the soil and all the treatments I've done are sprays.

I also included a picture of the pistils browning prematurely (imo) that might be due to these issues. I'm in week 5 of flower and can't find some of the sources I've been reading that led me to think this.

Veganic NYCD in 100% coco
Did you ever find out what these are? I’ve had some on the veg plants and now flower. I grow coco. They don’t appear to be eating the leaves but I am positive I’ve seen their little round eggs on the leaves which makes me think they are some kind of mite. I’ve been doing azamax and spinosad soil drench too in order to kill them systemically if they are eating the leaves.
 
Has anybody used merit 75 or bayer tree and shrub shortly after sowing seeds? I have a crazy root aphid infestation in my compost pile and greenhouses. I have added beneficial nematodes to the pile but still have RA's just in lower numbers. Im wondering if adding the imid from sprout will have any ill effects on the seedlings? Anybody tried this?
