I have some family friends that hold a bee problem. The bees, from what I have been told, are making their home within a hole in the cement of the back court at this property. How can my friend's mother successfully spray and kill the bees without getting stung? Will she own to call an exterminator? If so, how much do they usually cost?
Answers:    If they are bees, you would call a beekeeper. He will come and find the queen and move it to another home. The colony will follow the queen. He may clear you for the bees if he sells them.

If they are wasps, there are several products available through drugstores or home stores (like Home Depot). Choose any one of the sprays. Wait for the wasps to be inside in the evening and then spray to all comers around and into the opening.
Smoke confuses the bees, if you smoke them they will not sting I have done it and I enjoy stood in the middle of hundreds of bees without protection and short been stung. While you are smoking them you can spray them with wasp bloodbath spray that shoots to about ten feet away. One precaution you can steal if you don't have faith within this technic is to ware goggles because when bees and wasps sting they normally go for the eyes. (The wishy-washy point) Another thing that is frozen to believe but is true is that even a wasp won't sting you is you are holding your breath, is like they can't detect that you are a live person. The best means of access to create a good cloud of smoke is to burn dry leaves in a metal container. If the bees are greatly you better get a couple of cans of wasp spray. The regular bees (not the slaughterer bees) are normally peaceful because when they sting their guts progress with the sting and they die. But wasps you have to look out with because they don't die when they sting, so they won't think roughly speaking it twice when they're going to sting. Still they won't attack you when you hold your breath and stay calm. What I do when I find a wasp nest is I get a broadsheet bag and while holding my breath I bring the bag to the nest and pick the nest up by its stem beside the nest inside the bag. Believe me this works!! This I learned from a cousin os mine. When he told me I didn't believe him but soon he showed me that it works and I became a believer. Or you could take Beenther's proposal about the bee keeper, if you can find one. if they are bees and not wasps i would appointment a professional because right now we are LOSING way too plentiful bees to exterminate more
