2 Litre - GnatNix

Superb product. Works. Only thing that eradicated those bastard gnats.

It did almost nothing to stop the gnats.

was having a real problem with those indoor flies and could see them in the compost. Got this and along with another helpful hint of watering from the bottom up, my fly problem has disappeared

I got this from Ebay because I had so many gnats on my indoor rubber plants, but despite using this I still have so many gnats and have to end up killing them myself, so I do feel that this was a waste of money.
