# HELP! I have just repotted a BUNCH (like probably 20) of my sprouts…

_Posted by Jo on 2025-02-18_

HELP!

I have just repotted a BUNCH (like probably 20) of my sprouts into bigger pots. A mix of things- Cinderella pumpkin, cherry tomatoes, beans, carrots…

I noticed when I was done that two of the pots had what I believe to be Fungus Gnat larvae milling about on the top soil… IM DEVASTATED!  
Those two pots are quarantined to another area. I have never had to deal with this problem.. which I’m assuming came from the bag of soil I used. (Only those last two pots got the soil from that bag)

I haven’t watered anything yet luckily so I’ve read I can use a hydrogen peroxide solution to get rid of the larvae, is this true?? Does it work? Is there a better way to get rid of them?? Will it harm my little baby veggie dudes?

Plants are about 1-2.5 inches tall in 6-8inch pots, indoor with grow lights!

I’d recommend using fungus gnat death drops, I’ve seen it work like a charm and much less work than repotting everything or using the stinky mosquito bit tea. Also, I would get either some sticky traps or zevo plug in traps because those larvae will be adults in the next day or two, they have a really fast life cycle and basically live to lay eggs

Yes, in a pinch use a 1:3 peroxide : water drench. There's a few people on here that use it ever water. I use beneficial microbes, so I use a specific fungas gnat killer

You can just use mosquito bits, paired with the sticky traps. The death drops I’ve seen floating around on Facebook have mixed reviews. Some people say they work great and I’ve seen a couple comments say that it didn’t work and their plants started dying. I personally haven’t used it, and it’s more expensive than mosquito bits so I opted not to buy it. You should use the mosquito bits with every watering for a bit, you will have to research for how long because idk if it’s a couple weeks or a month 🤣 sorry. I haven’t had to do this yet. I’ve been noticing a fungus gnat or two flying around occasionally and I usually smash it with my hands like it’s a mosquito. No outbreaks yet and I’m praying it stays this way 😭

Thank you everyone! 💜  
I think for now the little nasties are dead and gone, but I’m watching that pot like a hawk!

I had this very thing happen last year! I had complete success with the hydrogen peroxide solution.
