Fungus Gnats or Root Aphids (Cross post from my journal)

I posted about this in my grow journal but i want to make a thread here too cause I know some smart people hang out here, I hope that's okay.

Got some bugs in the tent somehow. Haven't seen any for a year or so. At first I thought they were just fungus gnats but now I'm questioning myself. I managed to pluck a TINY (mite size) crawler from the soil and it looks to me like a root aphid nymph or a soil mite, not gnat larva. But the flyers look more like gnats. What do u guys think? Plants look okay for now.

heres a video of the crawler i plucked from the soil crawling on a piece of paper. playback at .25 speed you can kind of get a look at how the thing moves

Right now the plan is to either do a H202 or spinosad root drench but looking for opinions before i do anything.

Gnats. You can sprinkle a bit of DE powder, though it's never done much for me. Let your pots dry out a bit more between watering if possible, those yellow sticky traps are your friend, you seem to have a few already. There's plenty of sprays Chem and natural that will take care of them too, if they are really bad. More annoying than damaging, usually. I had them pretty bad once, and I cut a small hole out of center of sticky trap and laid it on top of pot around plant stem. That took a good dent of of them also.

OH I meant to add, sprinkle the de on the top of the medium, and those sticky traps, they work a lot better when left horizontal than hanging vertical. Also, air circulation keeps them from wanting to stick around as well. Good luck. They are annoying as hell.

I had issues with them a while back and started adding neem seed meal to my soil when transplanting. Havent seen them in a long time now. Soil smells like ass but no gnats. Can topcoat existing pots too just careful in flower it adds Nitrogen and not as effective.

BTI is very unreliable and I have spent way too much on that from granular version In the past and wish I didn’t ( bought bucket amounts for indoors and out ) to liquid version which is 16x stronger and that still didn’t eliminate them in the battle. I even play in coco of doing as far as I can go with dryness without capping and i was having def fungus problems . so I know I’m not having “ over watering” when these pots are super “ liftable “ on the test vs wet.

i so wish I would of learned this “trick” along time ago. Def easier on the wallet and it works within 24 hours and you def won’t have any fungus gnats after this Inless the nematodes are a crappy source. and that’s not hard to get

key price vs price on a reduction and how efficient it is, nematodes and rove beetles work better . Nematodes kill the larvae and rove beetles kill and hunt for the adults + put yellow cards for anything else and a good way to know if your getting them down by number is change your card weekly and see if the number is going down.

best way I ”win” the battle indoors of fungus gnats apply nematodes after 4-6th week and and also apply it to your flower room if you have it ( which that will be in early to mid range as well) and that will keep all the gnats In check. I buy the 250 mil nematodes instead of the 50 mil cause if you look at the price, they range ape ya on the 50mil and shipping is over 50% of the price. Might as well do it right and win the better eh

same with gene rove beetles, more population def wins and you can do both rooms and I even see rove beetles the next round in my coco when I haven’t even grown in the medium the whole summer. They are a amazing just like the h mile that they can survive that long .

big tip is never buy any bugs or nematodes from non big wholesalers like amazon or non certified cause they can so rip ya off and give you dead spore nematodes and whatcha gonna do? if it was me I will pay the if not same price and buy from the creditable people and be it from the source so it’s good stock since loook at nematodes c are so fragile you should even apply them in the dark or when light isnt on or full ( less the better, outdoors I do it sunset ) just read the pdf on nematodes and you’ll be okay, it’s super easy but like example there’s some nutes and certainly things they def don’t want you to do or timing on their products.

Nematodes 4 fungus gnat aka larvae eater

Rove Beetles aka adult killer for fungus gnat ( good for indoors, wouldn’t suggest for outdoors But hypoaspis mite would best choice)
——
Best example of the best “bug store wholesaler “ is evergreen, not only A+ service but they know their bugs and bad bugs. If you can’t confirm it. All you need is a good picture and email it to them. They can confirm it and it may save you some cash and also redirect you to a different product cause the correct product means everything on killing/prevention.

Thank you for all the info guys. Really good info all of it it. I turned out to be lucky this time. Minor fungus gnat infestation that is already gone. Not seeing any flyers or crawlers now or damage anywhere. Should’ve in the clear. I was puzzled as to how the hypoasis miles made it in there, but then I realized they made it in the same way the fungus gnats did. Life finds a way.

back on track now. Flowering girls in week 5ish. Got the UVB running 4 hours per day now. Next gen vegging out.
