Getting Rid of Fleas in the Home?

Very hard work, I'm afraid. First of all find the source if possible. If it is your dog than you'll need to get the house sprayed and the dog treated at the same time. No point in taking poor little dog back into a sprayed house if he's only going to dump more fleas in the carpet! Not to mention how bad the spray might be for his health. When we had fleas I bathed the dog with an insecticidal shampoo and carried him out to the car. Stage two: I left the house for the day while someone else did the spraying, only coming back when the instructions said it would be safe.
It might take a few goes, but eventually with modern flea sprays you will be free. Expensive, but not so much as employing someone else.

Another thought - a steam cleaner might help with maintaining a flea-free environment.
