I have been asked to do a removal in the spring, from a storage area inside a church. The front wall of the church is block with brick up to about 10 feet, and then it is framed 2x6's with vinyl siding. There is floored storage space above the foyer with 6" Styrofoam insulation in the walls. The bees have chewed out the insulation (they actually chewed through to the inside) in the wall for comb space, and they might be in the space between floor and the ceiling below. I will have to access the job from inside and probably won't be able to use smoke. I'm sure there are other problems associated with indoor cut outs, so I was hoping someone who had done one could give advice.
