Gnatrol has obsoleted Dunks at my house. Boom! Boom! Out go the lights! This is the only treatment that I have observed gnats fleeing soil when applied. Two gnats in three days on sticky cards as opposed to dozens on cards each day previously. Same basic makeup as Microbe Lift. I mixed 1 teaspoon per gallon which is recommended for “light” infestation and I feel my herd was more than light. Extremely fast which I did not expect.

Gnatrol and Dunks are the same Bacteria. If you grind up Dunks, you can water it in the same way. Gnatrol just saves you the grinding.

I cancelled the amazon order because my local shop carries microbelift.
When you say 1-2 drops per gallon does that translate to ml at all? I have 1ml droppers that I can use to measure small quantities of liquid.I got this one and it works

Two words: Hypoaspis miles. 1000 of these soldiers cost just $17. They will not just take care of your gnats they will keep them at bay for months if not years to come

Are fungus gnats even bad? Do i need to worry about these guys??

For me experience was worse than spider mites. If you have couple flyers around not a big deal, but in big numbers and untreated they will devastate your plants after some timeAre fungus gnats even bad? Do i need to worry about these guys??

Thanks @paraordnance !! I have neem oil spray- apply to soil? Strength/frequency? Also just put out some bowls with cidar vinegar to trap/drown the adults...

I tried everything to get rid of them. And nothing really worked until I introduced predatory mites that feed on fungus gnats larvae. Mites will establish themselves in soil and you will never have same issue again.
Try adding neem oil to your watering schedule, about every second or third watering. Just soak your pots. Usually about a teaspoon per 2 gals is sufficient (imulsified). This should help as preventive measure but will do little to deal with full blown infestation.
Also vinegar is a good idea dealing with pesky adults

Not in small numbers as has been stated. But if they get out of control the larvae can and do start eating roots. I have dealt with them numerous times as a pre mixed soil water only grower. I just dealt with one of the worst infestations in years on the run in my journal.Are fungus gnats even bad? Do i need to worry about these guys??
Neem oil, letting things dry out before watering, and an oscillating fan are your best defenses. Also try not to buy bales of soil with any holes in them.
I beat them back this time just like I have in the past. The yellow sticky tabs and I sprayed the shit out of the tops of my pots every 2 days before going into flowering. I did that over ten days, added a proper fan and let things dry out completely between watering.
Prevention is your best friend

I wonder if microwaving or otherwise heating/steaming soils to kill things first, but would need to start from scratch with the beneficial microbes that way...

You can top dress with nice thick layer of neem seed meal they hate the smell of it more then I do. You can also make a spray out of habarero peppers it kills on contact. Heating the soil up to a temperature that would kill the bugs would also kill anything beneficial in the soil which is not a good thing in organics. Predatory mites would be better since they wont mess with the good bacteria and fungi in the soil. You could bake the soil in the oven and kill off everything then add bennies back to it, but i would not put it in the microwave the metals in the soil will arc if there is enough of them.

They will not kill your plants, but the larvae do feed on the roots. They also are considered a carrier of pathogens. They are no good for your garden. Plus the adult gnats get stuck in the trichomes when you're flowering. I suppose it won't kill you if you smoke a few of the fuckers, but it's still pretty gross.Are fungus gnats even bad?

As long as there are still adults buzzing around they will just repopulate in like a week. They lay a shit load of eggs, and mature quickly.
I used sm-90, can't remember what strength. Maybe 2 tsps. (10ml)/gal, but definitely look that up first.

This method may not work for you, but you could employ these methods to kill the adults. But to get RID of them you have to completely eliminate their population. Or change the conditions which are favorable for them.

The microbelift is working just after a few applications.
It’s not an instant killer though. Those boogers are still in there.

For some reason top dressing neem meal did nothing for me. What is interesting is neem meal gets white and fuzzy after watering and guess what the fuzz is, right fungus. Fungus gnats were right at it crawling and feeding as usual.
Besides predatory mites, what really worked for me was Diatomaceous earth. As soon as you apply to the top of your pots you will start seeing dead gnats almost instantly. And they stay away. Works great until DE gets wet, and it will eventually, that's the bummer

I was referring to using neem oil, which kills adults on contact. Not neem meal. I have zero experience with neem meal. I have also heard get things about the Diatomaceous earth. Luckly I have never had to use it yet .

If you look closely I didn't quote you but JavaCo about neem meal. I have experience with both, just sharing it here with othersI was referring to using neem oil, which kills adults on contact.
