How to Deal with Fungal Gnats on Vegetable Seedlings?

Hey folks! I've been starting several varieties of vegetable seeds lately, but I've run into a bit of a problem. Every time I touch the pots, these little flies come buzzing out. My seedlings aren't doing so hot either. I've been starting seeds for years, and I've never encountered this issue before; I'm wondering if it could be due to the new seed starting mix I bought. Any advice? I've tried a hydrochloride solution, but it didn't seem to help.

You might want to check out Gnatrol! It's around $17 and seems to do the trick for a lot of people dealing with fungal gnats. Just a straight-up recommendation, but if you're looking for something effective, it could be worth it.

I personally like to saturate my seed starting mix with boiling water before using it. I call it 'dirt soup,' haha! If it’s not too late, you might just want to consider starting over, though. The gnat problem usually gets worse if you let it linger.
