I hived a swarm about 3 weeks ago and put in an Apistan strip to kill of
the adult mites and give the swarm a chance to survive.
 
 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?
