getting some nematodes now! 
@Barron make sure you apply them properly and keep the soil moist. Not water logged or really wet, just moist. If it dries out too much it can kill the nematodes.
I personally will mist the top soil daily after applying nematodes and just use sticky traps for the adults. After a week or so you will start having less and less adults make it to the surface as the nematodes breed and keep feeding on the larvae.
Once your gnats are gone move back to preventative measures like cycling wet to dry with watering and using DE and neem or garlic sprays as deterrents because once the nematodes run out of food they will start dying off and your soil will become vulnerable again.
They are super effective but unfortunately in container plants they don’t have enough food to survive like they would out door in soil once they do their job.

Mosquito bits. Soak 1/4 cup of mosquito bits in a gallon of water, use a stocking or fine mesh bag, for 30-60 minutes. Water plants normally. Use yellow sticky traps also. Within 2-3 weeks, should be under control. Some good videos on YouTube re: how to use and safety of product. Good luck.

Buy a bag of food grade de earth at a hardware store, let your topsoil dry completely bc it is dust, lighley dust around your plant and leave for 72 hours, give plant a light flush and check ph, you can wad a ball of TP and lightly dust fans or infected leaves, do not dust flower, cheap and organic will kill any pest with exoskeleton.

OK, not to get into conflict…Buy a bottle of my nano micelle solution…3.5 (light) to 7ml(Strong) per quart H2O…foliar spray and/ or top dress substrate…Done…no powders, breathing stuff, all organic, 2 weeks effigy. Good on Gnats, White fly, thrips, etc., …AND PREVENTS / KILLS mold (not if mold is tunneling inside the flowers, nothing gets rid of that) (ask @Jared -I sent him a bottle for his MOLD issue-ask his OPINION), washes residue WITHOUT THC degradation…
I guess I will be in conflict with HGCC who now sells their OWN insect spray, mold spray, root inoculate…So maybe this post will get blocked

De earth. A bag will last a long time and you’ll never have to worry. Also make sure you are not over watering that can cause nats as well. Hope you’re able to get those little bastards under control

I will let you know as I am in process of making a new batch…DE works but I find it difficult, messy and not really effective all by itself. Even with my solution, I will use DE as a secondary method but usually only ONCE…
Please email me

by the way, HGCC now also offers a bottle solution of 20ML at $30…go to the site and read up. They are doing 3 additives plus SOIL. My additive soes MOLD and INSCETS, all in ONE

I’m very careful with watering. Weight of container is very helpful w/this. Most of the time I micro feed and water. If it’s wet they will come. Circulating the air and a teaspoon of h2o2 in a cup of water works for me. I put that in a small pump bottle and mist the plants. Of course the soil can use another oxygen molecule also. I haven’t had to use sticky paper but, I just put some in. If you guys use it so am I! Can never be too careful when dealing with plant vermin. Just got over a frontal aphid assault.

Hydrogen peroxide is highly underrated as a tool in the grow room. And I keep the yellow sticky traps up all the time, I wanna know asap if I have something in there.

I use hydrogen peroxide in each watering, it drives out and kills the gnats and it adds oxygen to the soil. Hydrogen peroxide will not hurt your plants. I use 1/2 cup per watering can.

Just a heads up on the DE use it sparingly. I tried it at a half a cup per plant. It did not work at all and just gummed up my soil. From what i have heard since I used way to much.

With all the alternatives, DE is messy, can hurt the lungs, gunk up, and add so much silica in the soil it becomes detrimental to the plants. Why, especially if you are indoors, would you want to add a product like that. The alternatives exists, they work, can be 100 Organic non-gmo and just used in a spray bottle…Ask anyone who has used DE…
