The protocol

7-Day Fungus Gnat Starter Plan

Direct answer

The 7-day plan: manage moisture first by letting the mix dry as far as each plant tolerates, set yellow sticky traps at soil level to catch adults, and add a Bti product labeled for fungus gnats if needed. Heavier infestations need monitoring beyond day 7, because immature stages already in the soil keep developing.

Check off each task as you go; your progress stays on this device. Keep monitoring after adult numbers fall, and continue moisture management and any labeled treatment long enough to account for remaining immature stages — that's the step people skip, and a common reason gnats seem to come back.

Still seeing adults after day 7?

Keep going into weeks 2–4

That's expected for a heavier infestation, not a failed plan. If you're using a Bti product, keep following its label on reapplication; keep managing moisture for each plant appropriately, and replace sticky cards as they fill. Stop counting from zero and start watching the trend on your traps — a falling count week over week means it's working, even before it hits zero. See how to read that trend in detail.
