I am trying to do my first trap out and it does not seem to be working. I set up a hive box with a frame of brood and some bees. I then put the hive box on a stand so that when the bees came out of the screen funnel they would be at the opening to the box. The bees will not go it and now are getting very mean and stinging people that are not even close to the hive. What have I done wrong?
