I'm really having a tough time deciding whether or not I have AHB bees in my two hives or if I am simply dealing with an aggressive strain, It seems like any inspection causes a complete flare up of the bees, early on in the process, and I usually abandon the attempt. One hive was that way, and I tried to requeen, which seemed to be successful for a while. Then I started a new hive with new bees--quite a distance from the original. They were docile since last April, but now they are angry girls just like the first hive. How can I be sure what I'm dealing with.
