They don't sound happy.

Maybe you should call an exterminator?

There is a shortage of bees due to many factors. If i don't have to kill them, I'd rather not. It would be a last resort.   

And no, they don't look happy either!

Possibly an intruder in the hive or in the area?  Hope it's not Africanized Honey Bees invading, they can be deadly! 

Not to kill them, Barb. The exterminators smoke them up and then transport the hive to an apiary.

Make a special point NOT to kill them.... Oz is now in a panic because our bees are not immune/resistant to the bug that's decimating them in the US....[and we've been supplying the US with queens] as we need to introduce some european variety which IS resistant.....before we're in worse poo than the US....

sounds like they are getting ready to swarm?

ring up a bee keeper, they might take them off your hands ...

Taz, they swarmed once and came here from someplace, but it could be they swarm more than one time.  We called a bee keeper, but he didn't return our call. 

Safety first, tbc. Better to get rid of them.

 Taz!!!

You think you got problems...check this guy out! http://usnews.nbcnews.com/_news/2012/08/23/13435771-3-million-bees-seized-from-queens-ny-mans-home?lite/?GT1=43001

I really appreciate all these scary stories!!!  lol!  But they don't say how the bees get in the houses. Well I certainly hope it doesn't happen here.  I guess Monday we call an exterminator or something. 

Through cracks  and holes... their exoskeletons are quite plastic.

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)
