First of all, bees do not nest under concrete. They are wasps. The area can be sprayed with insecticide or wasp killer bought from a local garden store. A more safer option is to buy a wasp trap.

You need to be sure of what it is before you decide upon removal tactics. Is it a bee hive that is actually in the ceiling or wall, or is it a wasp or hornet nest that is visible and stuck to the ceiling or wall? If it is a bee hive there will be honeycomb involved and that will all need to be removed from the ceiling. Call a professional to smoke out the bees, open up the ceiling, remove the hive, and then seal the hole. If it is just the papery nest of a wasp or a hornet or the mud nest of a mud dauber, those are easy, get some wasp and hornet freeze. soak the nest and let it soak about 24 hours, then knock the nest down. Make sure before you knock it down you don't notice any activity.
