Any new tech for fungus gnats?

NanoGadget · Mar 25, 2018

Seeing a few of the little bastards buzzing around and it's been years since I've had em. In the past I always used a combination of microb-lift bmc and sticky traps or mosquito dunks and sticky traps. Just curious if there is anything new on the market that I should try that you all think is superior and why...

new tech says they are harmless

unlike mosquito dunks

best is still the 'old' lay sliced pototes or french fries on the top soil

remove and check for worms after 2-3 days

works great as I beleive its the worms that attack the roots

good luck

Yeah I know the adults aren't harmful.. but I don't want the larvae attacking my roots. I have heard the potato idea but wasn't sure whether it actually works or not... thanks Vos

GoGnats brand cedar oil soil drench. Not for DWC!

I spray my plants with eco-bb, it is also very good against mites, apply weekly before lights out.
It is a fungus and likes the humidity high. It is 100% lethal to adult gnats in four days.

It sells under a few different names, but they are all the same fungus.

Allow the soil to dry out a bit. Apply mulch and sprinkle on some diatomaceous earth on top. Re-apply as needed.

all you have to do to get rid of gnats is to stop over watering. not difficult.

fine screen mesh at bottom of pots, keeps'em out of the holes

top cover mulch of sand, fine gravel, or as a last resort perlite(dont want the dust blowing into flowers), keeps'em out of the top layer

done, organic,

and most importantly, what shrubber sed

Thanks for all the input y'all.

I didn't over-water, I am very careful about feeding/watering. I did, however, have my dehumidifier die and I didn't catch it for a couple days. Have to assume that was the initial cause.
Like I said in the first post, I've had them before many moons ago and I am familiar with the conditions that allow them to thrive. Mainly I just want to make sure the bastard offspring don't run rampant in my root zone. Was just wanting to see if there was new methods or products out that you all think are the best solution.
Soil is already dried out and I'll probably need to water tomorrow or early the next day so I was wanting to sort out my plan of attack before then.

No holes... smart pots. :-)

DE I assume would do the same thing to maturing larvae as they attempted to leave to soil as it does to the adults as they try to lay eggs in the soil. My question would be, how much damage would be done to the root system during the maturation process? I'd like to kill the eggs/larvae before they do damage with minimal harm to my soil biology.

100% safe for your roots and soil microbes. It is organic and is a natural source of silica once it breaks down. I even add it as a soil amendment. It's like thousands of tiny razors to a gnat larvae..kills them naturally and with extreme malice.

Thanks very much!

I am assuming that would be a no no during flower?

It's also not that simple. With ideal wet/dry cycles they won't ever get really out of control but it won't completely get rid of them either. Odds are if the soil is dry enough to kill the larvae it's also dry enough to kill roots.

Yellow stickies to knock the adults down and Gnatrol. It's a BT bacteria based insecticide that you water into the soil. About 2-3 days after treatment and they're done.

Garrett Juice and Orange oil combo - 1 oz. each per gallon, foliar or water in,

To be honest I'm a little itchy about applying DE to stuff we inhale

fine on my veggie greens but my weed I'm very cautious

I've heard of some nasty surpirises with this DE

but love ur posts either way

hugs from darkest Russia ..lol

I don't think so... It has no flavor or taste, it is just an invisible beneficial fungus that fucks up insects.
