There are bees in my wall in the framework behind the stucco, they made a little hole in the wall about the size of a dime. I don't want to kill them but is there something like an odor they don't like and then find somewhere else to house?

Not really. The queen bee uses pheromones and smells to direct the hive's activities(partially). You can't really overpower that from outside. If they are honeybees, a beekeeper will come get them. If not, call an exterminator.

Here's a website with tips on identifying which type of bee you have
