Borax??? Talk about a cheap treatment!!! Great!After vacuuming (and be sure to put the vacuum bag outside as soon as you're done), sprinkle Borax in your carpet and under all your seat cushions. You don't need a lot, especially if you're vacuuming daily, but it will kill fleas it contacts and help keep the population down. I did this with my cats and none of them had a problem with it. If you're worried about dog, or human sensitivity you could sprinkle the carpet and close of the room for a few hours. Just vacuum when you need the room (great for bedrooms that are empty all day, or the LR over night).
