Point me in the direction of a thread about nix killing mites please. As far as I'm concerned, in my one small battle with mites NIX is the saviour of my collection. Many many big breeders use it on their vast collections that make yours and mine look like child's play. If those people trust there $100,000 collections to it then so will I. Yes there needs to be some caution when using it as with all things, but it works. No doubt about it.
