Actually, the top of the french doors lacked weather stripping, that's where they were coming in and out. But it still seemed to confuse them. The hole you see in the foam insulation after removal was just a pocket that led nowhere. So the homeowner just had to throw in some weather stripping and they were done. I swept up dead bees by doors and windows, so I left the place super clean. I always can use them as a good reference.
