24 hours after all of the treatment was complete, my kids found 2 live fleas in the bathroom. There were two fleas stuck to the night light-sticky thing as well. It may take awhile to work, or maybe I need to leave it on the carpet longer. I left the treatment on for one hour, because I was doing one room at a time as I did laundry. I don't know if it worked or not. I think I'm going to try to re-treat with the same product and leave it on longer. Also, the dog was on Advantage, and I don't know exactly how she ended up with so many fleas on her or if she's bringing them in from some source. This is so complicated!
