Even if you kill the fleas, they WILL MOVE BACK IN. It's cause you live in a drought area with sandy soil. Your pet is a roving flea magnet, load that dog up with insecticide, keep the ac on, you can use borax on rugs, but also keep everything vacuumed.
There is a chemical called methoprene they treat your house with that keeps the flea eggs from hatching, works pretty well. You have to remember that the fleas you see are only half of the fleas there are. Most of them are eggs, and you cant kill the eggs, they are like impervious. All you can do is dehydrate them (doesnt work outdoors) or keep them from maturing (frontline, advantage, various other chemicals).
