maybe i have bad luck, but ladybugs are super super stupid... they fly into your light..
I've tried like 5 times to make a nice happy symbiotic ecosystem for them and they are dumb as hell, they either simply LEAVE your damn garden, fly kamikaze style into your reflectors, or simply vanish like a ninja...
You can try them, but in my experience it's not something useful.
If that's your thing, you can get praying manitis' those work better, but they eat a lot of bugs and run out of food quickly and then they leave too, and they don't eat mites.. neither do ladybugs... contrary to popular belief, i don't give a damn what they say, ladybugs don't show any interest in spider mites...
Aphids? hell yes, but not mites.
thanks grease would have sucked to went and got lady bugs just to have them burnt crispy all thru my room lmao (mass ladybug genocide)

I feel as though this would be super unlucky! Haha. If one lands on you, consider yourself lucky, if you massacre a lady bug tribe via burn sesh, you may be shit outta luck!!!

My homeowners association breeds gnats where I live, and I can't fix that.
So I had to come up with a way to fight a constant vector of gnats , with out spending $100 a grow on gnatrol.

I now use a mechanical means to keep gnats out of my garden.
It adds more work to transplanting but saves me money and worry.

I grow in solo cups, 1 gallon bags , and 3 gallon smartpots.
I top all my soil with a layer of weedblock landscape fabric cut to shape. I then top that with gnatgnix mixed 10:1 with diamataceous earth. I put my solo cups and my 1gallon grow bags into little wig caps, a nylon thingy for ladies, that shields the bottom from gnats.

I have eliminated them 100%. I see one or two drop in from time to time, but none ever stay.
I also reuse my weedblock landscape fabric and the gnatgnix mix a few times.

It's a labor of love. IMG_20150912_195603.jpg

That is GD dedication! But nicely done! Only first true grow for me and the growing and learning of tricks is almost as addicting as the anticipation of the final product! The growing process seems at therapeutic/medicinal as the smoke! Haha

OK... I know this is probably a stupid question, but... this is my first coco grow, and I'm still learning. It's also my first experience with fungus gnats, and now I understand what everyone's talking about. Let's just say it's one thing I really don't miss about rockwool or hydroton.

Anyway, I've got a swarm of the little fuckers now. Thought I had 'em wiped out a month ago with Gnatrol, but they're back with a vengeance. This time, I want to get them once and for all.

I think what happened is that I killed off the ones in my potted plants, but didn't do anything to kill the ones that were in other areas. For example, I've got a few pots where I cut off the males and didn't dump the coco, and another bag of coco that I leave semi-open most of the time, and some clones in coco... I didn't do anything about the eggs and larvae that were probably in those places, and that's probably how they repopulated. I want to learn from my mistake.

If I take all my loose coco, treat it with Gnatrol, and seal it up in plastic bags, that should kill everything in that coco, right? Then I just have to keep it sealed to make sure new eggs don't get laid, right? Shouldn't that work?

And for the 26 girls I have in flower at the moment, if the life cycle of the larvae is 2 weeks (which it is, according to the internet) then soaking the coco in my grow area with Gnatrol at least once a week should prevent them from ever maturing into adults, right? If I do all these things, within a month or so I should have no more fungus gnats, right? Or is it going to be harder than that?

And in the future, when I buy new coco, what about microwaving it before I use it? Shouldn't that kill any eggs in the new coco? Anyone ever tried that before with dried coco blocks?

Ive been battling these fuckers since i started . I have used gnatrol,Azamax,dunks,and others but they always come back and fuck my plants up. This time i have been using sand and it seems to work it just takes so much longer to water everything. I think im done with soil for a minute and gonna try an aeroponics system I'm putting together similar to Stinkbuds. Do you hydro guys have any problems with these guys?

Best thing I've found is a fan/fans on the floor of the grow room if the gnats can't fly they also can not reproduce the fans will blow those little gnats around and beat the crap out of them

Yeah, I'm noticing that if I keep a strong fan blowing a few inches above the pots, the gnats seem to fly toward the higher portions of the tent - where I have a network of fly strips stretched horizontally. I don't know if it's having any effect on the total population or their reproductive cycle, but it sure feels good to see the little bastards piling up on the strips.

Greetings farmer's. How long after spraying with any type of pesticides should you wait to introduce beneficial predator mites in to your garden?? Any and all info is appreciated.
