Hi, a question on sac brood....I have a hive that I did a newspaper combine on June 15....on June 27 nice brood pattern, saw open brood, nectar, and pollen. Not a lot of capped honey. Did not see queen either. Went in today, and saw what I think is sacbrood; compared this to pics I have. According to what I have read I need to requeen. I did see capped brood, but was upset at this turn of events and can't remember if I saw any larva (and did not see queen). This hive is small and has had a rocky start since coming out of winter (it was a laying worker hive). Will freezing the frame that has the virus sacbrood on it kill the virus and make the frame reusable? And could I reuse the other frames in the hive? Thanks for any information.
