I don't envy you a bit. We use Preventic flea and tick colors. If you have carpet get some salt and baking soda. My sister had a horrible problem when she moved into her new home (rental). She spread the salt and baking soda all over the carpet and the other flooring. It burns the fleas and their eggs. She has a shitzu and even sprinkled some on her. She said she saw the fleas fall off her dog. After couple days she vacuumed her carpet and swept the floors. The landlord replaced the carpet. Worst infestation she ever had experienced. But the salt and soda worked because of the sodium.
