Don’t panic. You don’t need a hazmat suit. Start with the easiest trick: let the soil dry out. Top inch of dirt? Bone dry. Then wait two more days. Fungus gnats can’t lay eggs in dry soil. It’s like closing the hotel pool.

Next, grab a pack of yellow sticky traps. They look like weird party decorations, but they work. Flies are obsessed with yellow. Stick them in the pot. Watch the little idiots get stuck. It’s satisfying, I admit.
Still got flies? Time for the big guns. Bottom-watering is a game-changer. Pour water into the saucer, not the top. The roots drink from below, and the top soil stays dry. Flies can’t access the wet zone. Bye-bye, breeding grounds.
The Nuclear Options (Use Sparingly)
If you’re truly desperate, try diatomaceous earth. Sounds fancy, right? It’s basically fossilized algae dust. Sprinkle it on the soil. It’s like tiny glass shards for flies. They crawl over it, get cut, and dehydrate. Nature is metal.
Or go for mosquito dunks. Yes, those waxy rings you put in bird baths. Crush one up, soak it in water, then use that to water your plants. It contains a bacteria that only kills fungus gnat larvae. Insects only. Your plant is safe. Your cat is safe. The flies? Not so much.
And for the love of all green things, quarantine new plants. For two weeks. I know, it sounds dramatic. But one infected pot can throw a party for all your other plants. Be the bouncer your fiddle leaf deserves.
