I have more trouble with small hive beetle than anything. I dont use any chemicals in my hives. My annual hive loss rate is ten to fifteen percent normally. I always start a few nucs and do a few hive splits and keep ahead enough to sell some bees. I just took 200 lbs of honey off my hives this past Saturday. I have sold close to half of it already. No doubt will run out by Christmas. Bees are not easy. Used to be, you could set up a hive in the back yard and they would produce honey for years with very little effort from the bee keeper. That is no longer the case. Oil trays are a must for hive beetles. I intend to expand my operation over the next two years. It can definitely be profitable, but dont think you are going to set up some hives and ignore them until you rob them.
