I got rid of most of them, only saw a few hanging around when I got home tonight, nothing like it was last week. I'm planning to wait until it gets cooler (like November) and then get a ladder and go around the house and see if there are any holes they could be using to get into the walls of the house. If so then treat them and the seal the holes. According to what I read once the weather cools they all die off and go away and vacate their nests and then they start all over again in the spring
