Description
Using the NemaKnights Fungus Gnat control can act as a preventative measure against fungus gnat populations. Beneficial nematodes for fungus gnat control allow the issue to be solved at the source as the fungus gnat larvae are eliminated by the nematode once it’s released by the adults. This stops the replication cycle and eventually eliminates the pest once the adults perish.
We do not recommend ordering the nematode products if the temperature in your region is below 0°C, or if the product will experience temperatures below 0°C while in transit.

My thrip/spider mite problem disappears when I use this product

Fungus gnat control
NemaKnights nematodes is a stable in my African Violet grow operation and for my many houseplants. I apply them to soil when I mix it in preparation for repotting plants. I have very few fungus gnats as a result and haven’t seen any other pests. It seems every soil type these days comes with fungus gnats. These nematodes are a “must have” for me.
