Dunno if you still have those bees. I been closed beta testing a computer game expansion and running my pretend legs off (we are on B4 with more to come but looking better - product release has been moved back a month)
Anyway to bees. Three reasons bees get that active. Reason one is they were just stopping by and now they are leaving for another place (yours probably didn't meet their standards. Sorry) Another could be is they are getting ready to split the swarm and half will stay just where they are. The last might be that they are being bothered by something, another swarm, some type of evil flying bug, or a ground-bound bug.
Swarming to somewhere else is a normal part of finding a permanent home. Splitting the swarm means that they have been there long enough to build some comb and grow some baby bees. Not usually likely with a hive that just settled in. Propelling unwanted guests is a viable option, but then the bees tend to be very, very aggressive. They cold be agitated if someone elsewhere gave the worker bees out on the prowl a good dose of bug spray, but it generally isn't very long lasting. The bees involved die off and the rest get back to work.
Wild bees can carry mites or fungus spores or virus that are a danger to domestic hives. In some areas wild bees are killed no matter what. Most of the time a beekeeper is more than happy to gather them up and take them away. There should be a beekeeping society in your area if not your state that can refer someone to rescue you. A bee keeper will likely put on his white or tan bee suit (supposedly more calming) and take his smoker to get them to ball up so he can dump them (gently) into a closed hive. Sometimes more drastic measures to even get to the bees needs to be found. In this case a beekeeper's best friend is their crowbar. The old timer bee keepers probably won't ever wear a veil - they'll just tromp right in with their head uncovered. Not this little grey duck.
An interesting note. Hybridization when African drones (boy bees) breed with European Queens (self explaining) results in a much more tractable hives. In Brazil, the source of this mess, they are selectively breeding quiet hives of African bees and ending up with much less danger than the original African stock. I guess they are really quite good producers. The two things that are most noticeable with the Africans is that they protect their hide at a distance much further than their European cousins and once agitated they have known to follow as far as a mile to chase the person/critter away. Their sting is no more potent than regular bees - there is always certainly many more of them. (if you are allergic, it only takes ONE sting anyway)
