How do I get rid of gnats in my soil? I’ve tried hydrogen peroxide and neem oil and that doesn’t seem to help. It’s a pretty big plant, so I’m trying to avoid repotting if I can.

One of the most effective methods I've used is Mosquito Bits (doesn't kill beneficial crawlies). You can top the soil with it or steep mosquito bits in water and water your plants with the tea.

No, plants don't mind it at all. Even sensitive plants don't have issues with it.

another unmentioned method that one woman in my greenhouse swears by is topping the soil with a bit of sand to trap/block gnats from the soil— but I would only recommend it as an additional precaution along with a systemic

I use a peppermint oil diluted spray… it’s plant and pet safe for the most part :)
