At the suggestion of my vet, I have used nematodes (one treatment) in the back yard and the Diatomaceous Earth (several treatments) in the house, dusted along the baseboards, the dog bed and even put some in a sock and used the sock to dust the dog (keeping it away from the nose and mouth). I got rid of the fleas. Gloria
