I agree with the thermometer, and stud finder. Find studs and cut along them. Make it neet so repairs are easy on the home owner.If you do it from the outside, get scafolding. Plan on several hours. I would make me a bee vac first. I think it's a must. Once you get alot of the bees out of the way ,it's easier for you to get the comb for the hive and the bees will have a better chance of staying.
