WRX forgot to add another important note abour "Nixing" your snake. Repeat spraying the Nix solution every week for about 3-4 weeks. That way you're sure any young mites from eggs which may be present will be killed too. Nix doesn't kill mite eggs.
Right, sorry about that!
I think Nix does kill the mite eggs though, as it kills lice "nits"
