Nowhere does Dr. Rodriguez claim that the bees will LIKE the FGMO.
In fact he warns of such reactions as you describe.  Too much mineral
oil will not only kill the mites, it will also kill your bees.
However, to answer your original question, the consumable mineral oil
used to relieve constipation is the mineral oil recommended by Dr. R.
