>>> I assume they have tested how much of this chem (Hivastan) ends up in
honey and it's effect on the queen's viability.
Fenpyroximate doesn't appear to get into honey, but it is lipophilic and, to
quote the company rep, "very stable."
This raises issues of comb contamination.  Long term studies on sublethal
effects on the bees have not been completed.
Fenpyroximate is also available as an ag formulation, so we can expect
commercial beekeepers to start applying it with shop towels, etc, soon.
