Mike: This is a little different then when the bees chew out granulated honey in crowded conditions to make room and spit out front. Pollen does get thrown out from time to time but not often as it is necessary for brooding. So question: In the corner or north side it is on: Did it get wet and mold to make for cleaning out? Did it get moth larvae into it being on side where small slit or opening could be to get bees to want to clean the pollen out? Other small insect burrowing into it to make the bees want to clean it out? Is it outside frame and next to wall? Just thinking about what you wrote. Regards, Dee A.
