>>Hivastan contains fenpyroximate, a highly effective miticide, that has been formulated into a "patty" delivery system. This stuff appears to be somewhat safe for humans (http://www.inchem.org/documents/jmpr/jmpmono/v95pr06.htm) in small amounts. I use OA to effectively control varroa and don't plan to use the new chem. I assume they have tested how much of this chem ends up in honey and it's effect on the queen's viability. Is there a link where one can view the results?
