I agree completely with the new meds out there for fleas. They have actually changed the world, at least mine. I use revolution, and am very happy with it. Back in the day, I had a very bad flea outbreak in a house I moved into. There are products you can buy to treat carpets, that guarantee no fleas for 6 months, etc... and are very expensive. I did some research and found out the primary ingredient of most of them was orthoboric acid, (most were 95% - 98%). I did some more research on the safety of it, and bought some at a do-it-yourself pet supply, raked it into the carpet, didn't vacuum for 3 weeks, gave the cats one more flea dip, and didn't see a flea in the house for the three years I lived there. I actually never saw a live bug in that house for the three years, and this is in a very wet part of Florida, aka "bug heaven". I had the occasional dead palmetto bug, but that was it. I used that stuff until I started with the revolution. And actually, I have used it anyways. Just some information for thought.
