Gnats

[EzPz]

I’ve used minticide, fungicide and instectisidal soaps and I still have small black gnats flying around and shitting in my soil. I got a good cause fam to lower moisture and the air flow is fine. The humidity may be a bit high but I’m unsure because I don’t have a humidity gauge yet.
any tips on how to keep them away?
I get maybe 3-4 a day.
I do kill them on sight but I need help.

go buy a bunch of these... you can monitor your infestation by the amount of gnats on a sticky card every few days or so. And blow some air over the plants so the bugs gotta land on something still.. gets um everytime. Keep up with your spray and you should notice fewer bugs. Diatomaceous earth dusted on top of the dry soil can also help. I'v seen them come out of the holes in the side of my hard plastic pots..so spray those too lol

You are killing the flyers, but the larva is still present in the soil. You need to combat both. Try mosquito dunks. Put them in the soil and in the water/feed. If that doesn’t take care of the larva, add beneficial nematodes to the soil. The dunks won’t harm them and they will eat the gnat larva.

I use a spray bottle with neem oil in the soil. Just a few spray over the soil - not soak it in. But just the top, it kills all the larvae.
and I have fly strips hanging in my tent as well.
too much heat and over water is the cause of it. I had a few days with almost 28 Celsius in my tent, and they love the warm environment, specially if you also just watered the pots Also

All great ideas pesty little soil critters won't harm but nuisance.

1 tablespoon of hydrogen peroxide per 8 oz. of water, kills larva in the soil. Covering the soil with perlite or DE can help, as can mixing DE into the soil. IDK if they are a real problem, but there damned annoying! Spinosad kills the flying ones, there is a beetle type bug that eats the larva IDR what its called (I need thousands of those)
BTW Neem oil should not be used on buds.

I use fabric pots and those yellow sticky’s and also just picked up some D earth. My infestation since my post has died down drastically. Now I have them all throughout my house lol!
