Last Week I received a great new product to test for fungus gnat control. It’s not an insecticide or a pesticide; rather it’s a barrier method for keeping the adult gnats for burrowing down into the soil of the plants and laying eggs.
Those of you that have followed me for awhile will remember that I have a huge problem with fungus gnats. The problem starts every fall–I’m already seeing traces of them but the problem isn’t out of control yet–and if it gets really bad it can persist into March or so.
I’ve posted about the problem last year and I spent most of February 2012 on a rant posting about in and all the different things I was doing to try to combat the problem since I had so very unwisely used some moisture control soil that I had left over from a client. By was that a learning experience! Never again!
This product, as you can see, is called Gnat-nix and it is made from recycled glass (which you wouldn’t really know unless you read the product literature or the bag). You put a 1/2″ to 3/4″ layer of the product on the surface of the affected plants and the pesky gnats aren’t able to burrow their way down into the soil to lay their eggs.
As I have previously explained in various posts (which start about here, by the way,http://wp.me/pOm4T-1ws), as annoying as the gnats are, it is the larva that do the damage to the plants. And of course, the larva grow up to be more gnats, causing a vicious cycle of gnats, eggs, larva and more gnats. By mid-winter, the gnats are dive bombing your food and drink. It’s just delightful.
So I have high hopes for this product and getting ahead of the fungus gnat problem this year. I’ll keep you posted!
