The FGMO I use is Crisco (Brand Name) its shortening that is in a solidified
form. I mix one pound of this shortening with two pounds of confectioners
sugar (powdered sugar). I spread about a tablespoon on the top bars over the
brood everytime I inspect a hive. The idea being that the bees walk over and
eat the sugar and get the grease on the hairs of their bodies and the mites
can not hold on and fall to the bottom of the hive and die. Hope this helps
someone.
