Hi Dave,
I hope you are not offended. The whole point of this forum is to share ideas and learn from eachother. I appreciate your tips and advice, even if I, personally, am not willing to try them. You've obviously found something that works for you that you're comfortable with.
I'm new to this whole "war on mites" thing and I'm not willing to spray ANY chemicals onto my animals. (Provent a Mite included). I understand that you dilute the Nix, as I'm sure Provent a Mite does, but I'd still only want to use anything like that as a last resort. (In which case I'd probably give Reptile Relief a try first, since it seems to have safer ingredients.)
I've got a permethrin spray insecticide that I will use on Monty's empty terrarium and then wash off completely several times, and let sit empty for at least a week before he goes anywhere near it.
I don't have a huge collection and I have the time to spend, changing my snakes to fresh containers every day and soaking them daily for several weeks to break the mite life-cycle.
Here is the site I got my info from:
http://www.vetpharm.unizh.ch/WIR/00005264/5531__F.htm It has dosis information for permethrin on everything from dogs to camels to turtles, etc. It's all in German, but the key words to understand are: Schlangen (snakes), Echsen (Lizards), Schildkröten (turtles), Reptilien (reptiles) and Hochtoxisch (highly toxic).
I know they are speaking of the undiluted form, but how can I be absolutely sure that it is diluted enough to be safe for my animals and still be effective on mites? It's not a risk I'm willing to take right now.
