Full out war with gnats !

[11Ron11]

I noticed gnats in my soil and buzzing around.
I have implemented a 1/2 cup of 3% peroxide and 1 gallon water mix in my sprayer.
I noticed it browned my leaves but I read it's good to mist the leaves so I'm confused.
Is a 1/2 cup peroxide to much.
I also put 1/4 cup apple vinegar in a jar with a hole in the lid to capture the adults.
I'm hoping to kill the adults with vinegar and larvae in the soil with peroxide.
Should I use less peroxide.
Should I avoid spraying the leaves.
Is it normal for leaves to brown.
So far it looks like it's working as the jar has a bunch of gnats and I don't see alot buzzing around anymore.
How long will it take to kill the eggs.
How long should I continue to use water/peroxide solution..
Thanks

I’m not sure how long the water/peroxide will take to kill the eggs. I really love having doctor zymes on hand for just your occasion. I would also recommend getting the large sheets of yellow sticky traps and cut a slit in it large enough for your stem to fit in and cover the whole pot. This catches the gnats hatching and leaving and also catches the gnats trying to go in.

I don't think you need anymore hydrogen peroxide. Just do what you can and watch your water. If they get too bad you could get some mosquito dunks or top dress with sand. The large sticky would be nice

Until we found the microbe life we would routinely struggle with them. Hand feeding lots of coco pots its easy to saturate too much. They are there waioting for yoi to overwater or feed once, the struggle begins. Big pots for those plants, not wrong but i would have a hard time getting them to dry back quick enough. Some guys have good results with big pots from the get go, i dont have the self control.lol.

Enough with the peroxide. Peroxide might kill a few larvae and a few eggs, but it will mostly go toward oxidizing your organic matter and be neutralized to just plain old water. Wet soil is excellent habitat for fungus gnats.

Mosquito dunks are fine — WHEN YOU NEED TO WATER. There is no need to fight a pest that isn't much more than a nuisance by overwatering and causing further problems.

You can also cover your soil with about 1/4 inch of diatomeceous earth, use predatory mites and/or beneficial nematodes. Mites and nematodes will take a little longer to be effective, but once they establish, gnats are rare.

I've always considered Gnats a non issue, They don't seem to stick around long. I've heard them to be a problem so when I do see them I act quick with clip on fans right over the top of the pots & I'll scrape the top inch off the soil around the edges. I always have sticky tape or fly paper around. but I think the fans do the job by not letting them fly. After the soil dries I'll add more soil to the top.

I'm not watering anymore then I would if If it was straight water.
Peroxide is supposed to help control fungus if you water Normally.
I'm a newbie so everything I say is just from things that I researched not from personal experience.
Somepeople say gnats are no harm just annoying.
Some say the larvae eat your roots.
1 gnat can lay 100's of eggs so when the adults die new ones are born I don't want to ignore and have a infestation.
I seem to have solved the problem hopefully as I don't see anymore buzzing around.
I was worried at first because it discolored my leaves but that seems to have gone away.
I'm going to continue to use the 1 gallon and then I'm going to lower to a 1/4 cup peroxide as I think peroxide just makes sense if used right.
Adds oxygen to soil kills bacteria helps roots grow and acts as organic pesticide.
The benefits seem to out way the cons.
As a newbie this could be my down fall follow my diary to see..lol
Sad part is i bought the expensive organic soil next time I'm sticking to the miracle grow stuff atleast it doesn't come with bugs..
Thanks!

I recently got some kind of Supergnats that don't mind Neem spray. Microbes didn't even make em flinch.
So i amazon'd a 50lb bag of diatomaceous earth for 50$. I spread a layer over the top of the soil and put some in the saucers under each dirtbag. It got rid of the gnats .
And DE provides some extra silica
