Grab a bottle of nem oil. Will do wonders for u. or make your own traps with apple cider vinegar and some liquid soap. yellow sticky traps hung horizontally over your soil works as well. good luck!

SNS 203 if all else fails. or you can just grab that first. prolly will solve your problems

The reason you see so much conflicting measurements for H2o2 is that there are varying strengths of H2o2.

I can get 3%, 17.5%, 34% etc.

That's why there are different mix ratios per litre or gallon.

I understand that, which is why I was asking how many ml of 3% hydrogen period I need for a litre of water. But I never got a actual answer from anyone so with the research I done I decided to go with roughly 1:5 ratio And it seemed to be fine

At 3% you could probably use it neat lol.

I've been using "Mosquito bits" with good results. Microbes in it target fungus gnat larva and prevent reinfection. I use about a thimble full in a 20 gal nute tank. Gnats are gone, no other observed effects.

For soil grows, the hydrogen peroxide is only used in the soil if you have root rot (as far as I understand it). For gnats, thrips, and other pests like it, a mix of hydrogen peroxide, detergent (like Dawn), and water is SPRAYED on the plant every day until the problem is remedied. Make sure to spray under the leaves, too.

Also, before you spray, you can take a Q-tip and dip it in a mixture of whole mix + baking soda (1/4 cup milk + 1 tsp baking soda should do it), then use it to wipe away fungus and visible pests. Careful to not contaminate "clean" areas of the plant. Use a new Q-tip for each leaf. Then, after you've "cleaned up" the plant(s), spray them thoroughly with your peroxide/detergent/water mixture. Or, you can also spray the plant with the milk / baking soda mixture (but you'll need more of it). You just have to be careful to check your pH from the water that drains out of the plant after watering, and adjust as needed.

If you put a layer of sand on top of your soil (about 3/4" - 1'), it will suffocate larvae, etc. I keep sticky sheets on top of my soil as a preventative. At home depot, they have refill packs of round sheets sold with the flea control products. They are perfect size and shape. I cut mine in half, notch out a little bit for the stem, and put the 2 halves back together around the plant(s).

Thanks for the info. But they are moved outside in the ground now so it not really an issue for me anymore. im hoping mother nature will take care of the rest for me plus i pretty sure i got rid of them before i moved them but it was only a couple weeks so im not sure
