Today I noticed that there were a bunch of white corn kernals at the entrance, almost like mummified larvae. Inspection inside showed a nice pattern of brood with a few white kernals inside some cells. IF I read this right... this is a sign of "Chalkbrood". Is there such a thing as brood being affected by an overdose of Apistan?
