Destroy Gnat Larvae Before They Harm Plant Roots

  • Just one application provides permanent protection!
  • Makes 1 gallon of concentrate, enough for all your plants
  • Easy to use — mix with water and spray on soil
  • Safe for people, animals and the environment

Those little black flying insects that hover over your houseplants are not just a nuisance. They're destructive fungus gnats, which live in the soil and produce hungry larvae that devour plant roots. Gnat Guard to the rescue! A single application of this biological control (naturally-occurring beneficial nematodes) gives your plants permanent protection against gnats and thrips.

  • Tiny sponge containing naturally-occurring microorganisms (beneficial nematodes)
  • This product needs to be either refrigerated or applied upon receipt

      Comments about Gnat Guard:

      Instructions about keeping it refrigerated were not clear to me, so I did not do this initially. By the time I used it, the gnat problem appeared to be gone. Therefore, I cannot say for sure about effectiveness.

        My new hibiscus was overrun with annoying gnats plus they were spreading to other plants. Within days of an application, the numbers were down dramatically. After two waterings, they were essentially gone. I haven't seen them in several weeks now. It really worked!

        The concentrated sponge made plenty of formula for all my plants whit more to spare.
        It worked within a few days and literally pulled one from the grave, as it were!
        I have struggled with Fungus Gnats for a long time never knowing there was an end all out there. I recommend this to anyone battling with House Gnats that are killing your plants.

              I have a major infestation of fungus gnats so I ordered this. I applied this to all of my houseplants. It did not work. I thought perhaps I applied it wrong so I reordered and reapplied. This did not work...twice! I really really wish I could get my money back!

                Comments about Gnat Guard:

                I had this gnat problem last year with some specific plants that need lots of water and just changed all the potting soil to solve the problem until this November. I liked the idea of trying this product but I do not know if the nematodes were not alive or active - even though I used them the same day I received them. I still have gnats after a month. I would like to get a new batch but it is a little expensive to experiment again so maybe I need a refund!
