Never forget 'mite sprays' for the most part use a chemical that started life in a bit more basic form as 'snake spray' designed to kill snakes. Accidental poisoning has occurred and will again. It is poison and just to add a little tidbit is also a human carcinogen (weight of evidence). I would not recommend using it as a preventative product, and only as a treatment for snake mites and even then with caution.
