I paid a pro with no results and was recommend to use Amdro by a landscapers. It really works because it kills the queen. It does take two weeks but once she is dead they disappear. It might need to be done a month later but I really is permanent solution. I also have cats and dog and had no problem

Amdro Ant Blocker is the only thing that works.
