A Vet I had a long time ago told me about and older couple that couldn't understand why their house was infested with fleas because they didn't have a dog or a cat. After many questions and all, it was learned the older gentleman still wore pants with cuffs on them. That's how the fleas were getting in their house. When he would be out in the yard working or whatever they came in the cuffs of his pants. Once they bombed the house and he changed his style of pants, the fleas no longer were in their house.
If they are in your house, so are eggs. I was told you need to treat the house first. When I had a poodle and our house became infested, While I bombed the house, I had the poodle in for a grooming and flea bath. No more fleas. Right now, Frontline Plus and Revolution work for us.
