Helpful Tips

1. This product works best in conjunction with our living soil bio-diversity packs as they will not adversely affect any of the beneficial organisms in those packs. Our BTI will immediately start incapacitating the fungus gnat larvae as the beneficial organisms grow in populations to be able to take control of the soil food web.

2. We recommend taking a look at your watering practices. In the first two to four weeks depending on the severity of your gnat issues), it is recommended to run your top layer of soil on the drier side to further discourage the gnats from reproduction.

3. Direct some wind across the top of your soil pots to help dry out the top layer and to keep the pressure on the gnats.


We recommend storing all dry amendments and nutrients in a dry, cool location away from direct sun.

The 1-2 Punch on Fungus Gnats

Did you know that gnats can quickly develop a resistance to sprayed products and even BTI?

Using our Organic BTI in conjunction with Rove Beetles or our Biodiversity Pack is the best way for sustained gnat control. The BTI will diminish the gnat population quicker , but the beneficial insects provide long-lasting and regenerative fungus gnat control. The only option to fix your gnat issues long-term, is utilizing soil predators found in our Biodiversity packs.
