Why Fungus Gnats Keep Coming Back — Break Their Life Cycle for Good

Fungus gnats keep coming back even after you catch the adults? The reason may be hiding in your potting mix. In this video, I break down the complete fungus gnat life cycle — egg, larva, pupa and adult — and show you how I tackle each stage instead of relying on a single quick fix. You'll see how to tell fungus gnats apart from fruit flies, how they can enter your home, why I isolate and inspect new plants, how moisture affects their life cycle, and how I use Bti (Mosquito Bits) to target larvae developing in the potting mix. I also show how I use sticky traps and an electric flying-insect trap to catch and monitor flying adults — and why adult traps alone aren't enough to break the cycle. In this video: • Fungus gnats vs. fruit flies • How fungus gnats get into your home • Why new-plant isolation matters • Fungus gnat egg stage & moisture management • Larval control using Bti / Mosquito Bits • Why adults may still emerge during treatment • Sticky traps & electric flying-insect traps • How to target the entire fungus gnat life cycle When using any pest-control product, always follow the directions on your specific product label. 🌱 Subscribe to Vishnu's Green Vault for practical indoor plant care, potting mixes, propagation and more.
