I don't want to get this thread too off track, but here's some highlights from the guinealynx post I linked to:
The only active ingredient is an antimicrobial product used on to prevent cut flowers from getting moldy and an agent to inhibit Botrytis cinerea infections in grape vines. There is absolutely no doubt this is not a miticide and would not kill the mites at all. The reviewers mentioned its toxicity, impact on the environment, effect on human health, and on organic agriculture. It's also not approved by the FDA to be used on animals. To treat mites there are better and safer options (not to mention proven to work time and again) in the form of
ivermectin.
