Fungus gnats!!!!! Organic control methods

I am surprised no one has said gognats! it is organic, mostly cedar tree oil. The gnats will be gone for a loooooong time after a couple applications. smells good too lol.
What...from cedar trees?....That's one I truly would have never even suspected. What about the acidity? Would it f#*k up the microherd? I'll have to research that one for sure. Wow,....who'd a thunk it?!

drosera are the best carnivorous plants for small flies......them and pitcher plants..

Lol IC is going to be the newest CP forum. Anybody want so
e bare root plants? I got adelae and binata I can divide.

So what medium do you use? I go with 50-50 peat and perlite. The peat in one pot came to life and is growing. No shit!

Did a little looking into Scanmask,and Gognats. Scanmask being beneficial nematodes for a variety of grub/larvae type pests. It's an organic form of control and should have no impact on anything but the bugs. Gognats looks very promising. It not only controls gnats,but several other common pests like mites,whiteflys,etc. Made from cedar oil and soap,claims to be safe for organic gardening. I'm curious if this would be more effective on mites than neem. The Bacillus thuringiensis method has some issues involving the application on food crops and the demise of bees and monarch butterflys,but seems safe to use on an indoor garden. There seems to be no effect on the other micro organisims if used according to directions. Here's a link(if it works) to a study about that http://www.erudit.org/livre/pacrim/2005/000234co.pdf
The carnivorus plant idea sounds great if you could actually have enough of them in your room to be of use as a form of control,wouldn't hurt to have a few hanging out in the corner.
If there is anyone out there with more products and ideas let us know. Remember,this is organic methods of control.

find a good pheno of the Blueberry strain and flower it in your cab/room
the gnats are attracted to it like flies to honey and stick to the buds like sh1t to a blanket :D

That's funny V,I had some Hawiian X Cotton Candy that does the same thing (there's blueberry in it) They really liked it and coated the buds. We cured them up as if they weren't even there. Most fell out,but others were turned into vapor.
 
No really I love my sundews, but they have to be kept in standing water And peat to thrive. Breeds more gnats than the plant eats.

Not a solution, but I still recomend them. They give you perspective.

I tried ordering mosquito dunks from overseas and they got confiscated by customs :( Seems like Bacillus thuringienis israelensis isn't allowed in Oz. Bacillus thuringienis is allowed though because I've seen Dipel available, but supposedly this doesn't work?

I'm using a layer of perlite with some diatomaceous earth sprinkled on top and it controls them for the most part, but my pots have many holes in them, ala diy air pots.

Has anyone tried Azamax for gnat control? (I think it's neem based/organic?)

Right on ScrubNinja! Just schooled myself in Azamax and diatomaceous earth. Azamax looks great,made from neem and OMRI listed. Safe for soil micro flora,worms,and beneficial parasitic insects. It's the bad news for Gnats,mites,whiteflys,etc. It disrupts the digestive system and starves them to death. I like the idea of this as an effective Borg solution. One retail source offers 4oz for $22.98...a bit spendy,but likely worth the $$$.
Diatomaceous earth is the fossilized remains of diatoms,a type of hard shelled alge. It works by dehydrating the insects. The fine powder absorbs lipids from waxy outer layer insects. Didn't keep looking to see how it affects micro flora,yet a lot of people add it directly to a potting mix,and some use it in hydroponics. It has a breathing hazard when working with it due to the highly crystalline structure of this type of silica. Sounds good,but may need more looking into the effect on micro flora.

diatomacious earth is harmless to micro flora - its basically just silicone. i dab a 2" paintbrush in it and then dust it on the surface of my soil by tapping the handle on the rim of the pot - this avoids throwing too much dust up. it works pretty well.

so can we definitely say that neem doesnt hurt soil flora? im a bit hesitant to drench my soil with it

Good question...I don't think I'd do it either. I'll dig around and see what I can find about it,but it is questionable. Interesting technique on the diatomacieous application V.

azatrol/azamax doesnt do shit to Fungus Gnats...go with Gnatrol WDG this shit after a few applications will have them all gone

1. water from the bases of the pots.

2. allow the top few inches of the soil to dry out.

and/or

3. add a top layer of clean fresh coco fibre or pre-washed gravel.

Hope this helps

I add powdered neem when making a mix,seems to do the trick.Also is a good fertilizer,think NPK's are 4:1.5:1.5 also high in sulphur and silica.

Okay,here's what I found; http://www.google.com/url?sa=t&sour...LpROHH4dVg8in8fFw&sig2=ERs2vztwFplC4LrOGrewtw

( damn,did that work?) Anyway,some species of plants apparently are able to take it up in the soil and it works as a systemic by killing the pests that feed on the plant. Moist soils reduce it's effectiveness. It kills nematodes and definitely has an effect on microbial populations. It wipes out some microbe types completely while allowing others to flourish. I personally wouldn't apply a soil drench of neem oil to my girls inside,maybe something in the garden outside where the environment has a way of balancing things out by itself.

There are other products here (OZ) containing BT, but they don't work!!

Azamax is too expensive and doesn't work.. Not for long anyway.

Oh, BTW, Fungus gnats breed in rockwool! And I've even had them breed in bags of dry propagating sand!

Forgot to mention.. Tobacco tea is the best drench, but very expensive solution in my case, be VERY careful with it.

Thanks for sharing that Capt. Reading the thread Darc linked earlier, it says gognats is not organic, just so ya know. I'm going to try mixing DE into the medium in future.

Here's a pic I snapped the other day. It was the hugest one I've ever seen. Is it even a fungus gnat?

Whoa. That thing is huge. I would keep it and observe it till adulthood. as for DE, try top dressing so when they creep thru the top of the soil, the higher concentration of being layered rather than mixed will slice the fuckers up good.
