This post reminded me I have to contact Iddee so I can send the sample of bees that attacked me from a swarm that was sprayed with a fire extinguisher about 6 weeks ago to get tested.
I have always heard that even Africanized swarms are docile for the most part as is a European swarm.
Dry swarms are the ones you have to watch out for. These have been clustered way past the normal 2 days or so, more like 5 days or more. Their resources have been depleted and they are very grumpy and hungry, just like we get.
Another thing, I read all the time, how someone hived a swarm with no aggression, to find out AFTER they have been established, they begin to become unruly, and sometimes nearly unworkable, and wind up testing positive for AHB traits.
