My daughter had the Orkin man because the animal with flees live there, cost was too much for me. I put amonia in a spray bottle covered most of my head, shut all the windows and sprayed as fast as I could, then ran out of the house. Came back in 1 hour, and I had the best smelling house ever, no smell of amonia either. Our flees came from a short visit with the little flee bag. They never came back. (the flees)
