I've tried mosquito bits myself, and yeah, they're effective, but honestly I found them a bit messy and not exactly budget-friendly if you're dealing with a larger plant collection. One thing that surprised me was how much difference bottom watering made. I stumbled onto it by accident—was away for a long weekend and left my plants in trays of water. Came back to noticeably fewer gnats buzzing around. Apparently, keeping the top layer of soil dry makes it way less inviting for fungus gnats to lay eggs.
Also, I've had decent luck mixing diatomaceous earth into the top inch or so of soil. It's natural, safe, and seems to discourage gnats pretty well. Just be careful not to breathe it in when applying—it can irritate your lungs a bit. Anyway, just thought I'd throw that out there since mosquito bits aren't always the perfect fit for everyone...
Interesting points about bottom watering—I hadn't considered how much it could impact fungus gnats specifically. I've mostly used it to avoid overwatering sensitive plants, but your experience makes sense. Keeping the top layer dry would definitely discourage gnats from laying eggs there.
I've also experimented with diatomaceous earth, and while it did help somewhat, I found it lost effectiveness after watering a few times. Maybe I wasn't applying enough or mixing it deep enough into the soil? Did you find you had to reapply frequently?
Either way, it's reassuring to hear others have mixed feelings about mosquito bits too. They're effective, sure, but not always practical for larger collections or frequent use. Glad you shared your accidental discovery—sometimes those unexpected solutions turn out to be the best ones...
I've had similar experiences with diatomaceous earth—it works great at first, but yeah, loses effectiveness pretty quickly after watering. A couple things I've found helpful:
- Apply a thicker layer than you'd think necessary; thin layers wash away too fast.
- Reapply every couple waterings, especially if you're watering from the top.
- Honestly though, bottom watering combined with sticky traps has been more reliable for me overall.
Sometimes the simplest solutions end up working best...

Bottom watering is such a game changer. I remember when I first switched—I was skeptical at first, thinking it sounded like some trendy plant influencer thing. But after battling gnats for weeks, I caved and tried it. Within days, my plants were happier, and the gnat population plummeted. Now my watering can sits lonely in the corner, judging me silently... but hey, whatever works, right?

Bottom watering definitely helps, but honestly I've found that adding a thin layer of sand or decorative gravel on top of the soil works even better for gnats. It looks good too, and my watering can still gets some love...no silent judgment here, haha.
