A beekeeper would be interested in relocating a HONEYBEE hive. NOT yellowjackets. He'd refer you to an exterminator.I would call a beekeeper/relocated hives rather than using poison.
Capturing a hive of honeybees that is in a house or on an eave or somewhere they are not wanted is called "doing a cutout." The person doing it is doing it for the bees, to add to his/her apiary. (They charge for doing this work too.) The bees might be behind a wall, under a floor, in a crawl space, wherever.
I have seen the work of someone who is VERY skilled at this. He has removed bees from hundred year old farmhouses, and the homeowner could not tell where he cut out pieces of the floor.
