To get rid of them on the dogs, I found that Dawn dishwashing detergent kills them but dries the skin out sometimes. Had gone on vacation and had my dogs at a family members house and after being exhausted from flying home to pick up my dogs, I had to give them a bath in Dawn. The fleas were literally falling off the dogs dead. Was very impressed. As far as the house, I really don't know. Never had a problem with them in the house.
