Its cool...obviously I hit a nerve.

BTW, I am not the one the chimed in this thread about a product that is not available to purchase on the internet. Standing by my words--"We will have to take your word for it".

I was also stressing about where to source my BTi from in order to get rid of them gnats.

Was googling this and that and stuff came up more and more confusing and I kept running into walls of "you can't get that here" or "that would cost 200% of item price in additional shipping" and that kinda crap.

After a lot of back and forth and deliberating if I should get this or that product and how etc. etc., I simply googled "bacillus thuringiensis israelensis" and lo and behold about a hand full of products showed up that were readily available to me. I didn't even have to order it online, I could get it in the shop around the corner.

I just didn't know because the product was marketed for something entirely different and I had googled for various products such as Gnatrol and stuff and fixated on how I get this or that product.

Instead all I really had to do was google the active ingredient and I found a whole list of things I could use and easily get.

In the meantime I had watered in several packs of nematodes which did help but did not completely eradicate the gnats.

Currently I have been watering with BTI for a few weeks. At the start I just applied it once because it said it was highly concentrated stuff I could use for entire ponds but since I apply it with every watering, the gnats have considerably reduced.
Also in size.

The only remaining flyer gnats I still see have gotten reaaaal tiny.

When I transplanted the seedlings, I did see larvae in the bottom layer of soil still but apparently they are getting fewer and fewer as well.

I resigned to continue watering with BTI for now and see what happens. If I haven't completely eradicated the bastards in a few weeks, I will add diatomaceous earth as a top mulch and probably also put the pots on a bed of that stuff to make sure these bastards don't get in through the bottom holes.

i have em all, tried most...

fought the unwinnable battle for over 2 years after getting root aphids from the first set of clones/dirt after a 6 year hiatus of growing...

outdoors they where present, in pretty good numbers obviously taking a tole but never seemed to slow the plants down, yield fine, quality was good.. natural predetors and outdoors enviorment makes RA not a huge problem, atleast ime

indoors with no natural cycles it a whole different story, a disaster, indoor growing with RA is a losing battle, i tried to beat em back without dunking, tried all the organic methods, met52,botanigaurd powder, foliar pack, they didnt seem to knock down an infestation that was already taken hold... what worked atleast as a temp knockdow was riptide at amything from 2ml-5ml gal, never did a full dunk or with orathene (idk why) so never got complete erradication, they always came back within a week, two at most, didnt seem to help the grow overall and all these treatments take its toll over the grow and phantoms defs, burnt buds, no thc, lower growth would ALWAYS yellow and die, where all symptoms...

the only thing that finally got me back to white fuzzy roots was to shut down my indoor tent, threw out all soil, took moms to aerocloner... and for a month didnt grow in dirt.. once i did i drenched heavily with x2 foliar pack.. cleaned the tent and used to harvest my outdoor, cleaned again.. and now its back in action and plants are noticably stronger andhealthier... the true test will be flowering cause thats when the RA plants would go down hill fast for me... but these White fuzzy roots are a GREAT sign im winning the fight, for now...

Well, I used to have Fungus gnats and now I don't.

Make of that what you will. Folk can take my advice and experience with using water dispersible granules of Bti, or they can leave it to waste.

Howdy folks,

I might have celebrated too early :(

I just germed a new pack of seeds and since then have had a new explosion of the flyers. Since I have been watering with BTI for the last 2 or so weeks (and felt like the pests were nearly eradicated), I was very surprised to see a new explosion of flyers...


So I took a pic. Maybe it is root aphids after all.

Otherwise the BTI would not be working for me....

Please halp (check pic).

If it is root aphids, I would have the added benefit of having nothing in flower now, so I could theoretically knock them out with systemic chemicals and just veg for another month before flowering them. That should be enough time to get out the systemics.

/Edit
I just checked page 1 again and to me they certainly look like Gnats (still) and not RAs...

Looks like a pointed abdomen to me

Which makes me wonder why the BTI watering didn't get rid of them completely and why I had a new explosion of them after germing a new round of seeds (which was watered with BTI as well)...

Obviously the environment in the propagator (very moist) is ideal for them and that seems to be their "source" at the moment as I had very few flyers around the veg room before germing the new seeds.

And when I opened the propagator yesterday, a whole bunch of them emerged and I saw them everywhere. The little seedlings are just tastier/easier to feast on and the environment in the propagator is preferred so that isn't really surprising I suppose.


Now I don't have mosquito dunks here but as I said above I looked for BTI and found a product with it, stating a few drops are enough for an entire pond of water. I applied it generously with my waterings and as I mentioned, I was convinced I was slowly winning the battle.

Until I germed new seeds ... And now they are back and their numbers are greater than ever.


I'm at my wit's end here...

Close to the point where I say "screw it, scrap everything, shut down for a month and let everything go bone-dry then reboot"...

But Fungus Gnats shouldn't really necessitate that, should they?


What also confused me is that when I transplanted the seedplants to bigger pots, some of them had the soil break apart because their roots were so weak and I saw larvae near the roots, not in the top layer of the pot.
A good 1-2 cm from the bottom holes of the solo cups.

Maybe I need to take more pictures? Maybe I have both Fungus Gnats AND Root Aphids .... and the one I snapped a pic of just happened to be a FG...

Could also put some roots under a microscope I suppose...

Always have a few FG flying around over here nothing im ever worried about doesnt seem to be an issue roots exploding still. I use stickies top layers and stuff like sm-90,h202, and azamax in the res to keep em at bay. there's always a handful flying around. They come in my readygro I concluded. I just deal with em.



cheers

They are seriously negatively affecting many plants.

I would say about 50% of my plants that make it past the seedling stage grow as expected, strong, vigorous, great roots.

The other 50% are stunted, new growth dies off/yellows, growing super slow. When I repot them, I see they have close to no root-system while the other 50% have rooted through the entire pot as expected.

They are severely affecting my grow...

The other day I opened the propagator and I kid you not, they chewed off a seedling at the middle of the stem. Like 1 cm of the stem looking out of the soil, clean bitten off and a little brown/rotten at the point where it was eaten away. The top, another 1cm, lying in the solo cup...


I don't know, I think I just finish this round, don't keep any clones or mums and just throw everything away after harvest, then shut down the entire thing as I go on vacation for a month and then start fresh.

Hope it will be enough to let the soil dry out for a month so I don't need to mix a new batch of soil after.

I have found that shutting down is not a cure, by any means. When you shut down, the RA's just go into stasis, or their "overwintering cycle", and they come back as soon as food is available. You have to eradicate them while they are active.

I have shut down grow areas for over a year, only to have them come back the minute I re-introduce a food source.
