Steinernema feltiae can be used as biopesticide against weevils, cutworms, mole crickets and - importantly for house plants - gnats.

    I’m new to the concept of nematodes.

    What’s the general lifespan? I’m guessing you need to keep reapply them after a while ?

      As long as they manage to find food and don’t dry out, basically forever. My Nepenthes likes constantly slightly moist soil, so the gnats took a liking to it. At some point it got rather annoying, so I applied SF nematodes. Since then I see maybe one gnat per week.

      The gnats are not gone, but they now regulate themselves, so they stopped being a problem.

      Look at the entire physical world, look at a map of nematodes, it’s 1:1. Nematodes are everywhere and are a foundation of life.
