Does anyone use this, and if so, how? I've looked at a food grade package that recommends using a mask while using it. Should I be concerned about the potential for the quail to breathe it in? I have been considering sprinkling it in the areas where they sleep, nap, and dust bathe to prevent/eliminate any mites, but I am concerned about them breathing it and collateral damage to innocent insects. I appreciate hearing about others' experience with it. Thanks!
