Check and make sure they are honey bees. Yellow jackets and wasps are often mistaken for honey bees.
Once a swarm moves into a wall or hollow tree it is no longer a swarm and may need cut out. Many beekeepers do not provide this service due to the difficulty and expertise needed. Look for hive removal or cutout in the search results for beekeepers who will.
Don’t expect a beekeeper to remove a swarm for free. A few will depending on location, but free bees often costs more time and gas than purchasing bees. Hive removal and cutouts are rarely free due to the time, expense and liability involved.
