[QUOTE=aunt betty;1521483]If you've got SHB issues it is partly because you're giving the bees too much space.
+2. This is the most critical fix to your problem. What size boxes do you run and in those boxes, how many frames are covered front and back with bees? If you have less than 65%-75% of your frames covered front and back with bess, the bees have too much space to protect. Reduce your box size if possible, combine smaller weaker hives, etc.
