Taking a bee course or class in your area would be a good first step. Getting equipement, preferably new, this way you know that you'r not getting somebody's desase. Taking bees out ot a building without any loss is not easy, normally it will kill many bees, especially when done later in season when combs are heavy with honey, sometimes then the comb collapses and bees get traped and killed. The hardest thing is to get the queen. What I would do is this...build a modified super [bee box] with one side or back completely open, this side attachted to the cut open wall where the combs are, not too high and not to low..about center of brood area. Fill box with about 7 frames foundation, best use drawn foundation, put a little brood with bees from wall into the box for a bait. Eventually when the hive expands, the queen will go in there and lay eggs...hopefully??...make sure you're limiting their space in the wall, perhaps you have to close off some with wood. Bees will eventually use the hive box entrance also to get in and out to their colony...then you can seal off other holes they used to use. The hive should be checked first about after 1 or 2 weeks, or sooner at the peak of the season, then every second day or so until you see the queen. One's you spot her, take the box off the wall, close off the side of box, best leave the box within 3 feet the first couple of day's until they settled. Take out all comb with brood and put in hive with some honey. Perhaps use a second box if full? Clean out the wall completey, seal any holes, put back siding and and seal again. You possibly have more then 1 hive in this house, I have seen a similar situation with about 3 hives. There are allot of bee books out there, read a lot, check out Beesource Forum and read from other bee keepers. I have done a similar contraption,.. I made some brackets and attached the hive to the wall with about a 2 " hole in the hive box......it didn't work very well because I couldn't cut open the wall, I'm sure, this [new] way should work much better.

this post is late, but i thought i would provide this input since many new people search for the "removing bees" info. please don't chastise me for my actions, i am submitting this only because my experience may help. I had a swarm show up at my house in June also, and focus on a small construction hole in my stucco wall. i discoveredit just as they were setting up house. i spent several hours trying to find someone to capture the hive, no luck, and found no info online either about how to repell them, other than some obscure mention about tests with aromatic oils - cinnamon oil i think. i was in a panic, because this old house has no insulation in the walls, so the bees could concievably get into the attic and into the house through other construction holes. It came down to bee removal companies wanting to charge $250 to destroy swarm. I figured i could kill them for the cost of my spray can of wasp killer, and with a heavy heart, i sprayed into the hole, so that the product dripped down inside the hollow walls. The incredibly good news is that my product was a so called "green" product made with 0.5% eugenol (oil of cloves i think). Within seconds the entire swarm came rushing out of the hole, regrouped around the queen on a nearby bush for the next two days while the scouts found a new home, and then left for parts unknown. there were less than 10 bodies in the area afterwards, and my flower beds are covered in happy bees. i closely monitored the swarm for those two days, and to my untrained eyes they showed no ill effects - still lots of searching, flying, feeding, and trying to re-enter the now blocked hole. the repellent affect of the eugenol also worked for those two days. i realize this post will cause many to cringe, but i had no available options that day, and i wanted to post this to allow people to evaluate the affect of the eugenol. the product is "Raid Earth Options Wasp & Hornet killer". i do not use pesticides anywhere in my yard because of my native & honey bee population, and have this one can only because my wasp population is so healthy, they sometimes start nests right under my doorway.

You need to find a beekeeper that is willing to do a "cut out" removel, see if there is a local beekeepers club in your area and contact them, good luck

It is better to have them removed in the Spring, it is a bit late in the season. Konrad
