I did some late splits. October and November I fed them all winter so far. lost some but less than 10 percent. l opened a hive last week and there were as many shb as bees. l killed as many as l could but when l opened them today l expected a dead out. to my surprise l found capped brood and open brood. l took tweezers and killed every beetle l could find, this queen does not quit. it from Michael Palmer queen will update
