We are also flea central here and i used food grade DE in all carpeted areas and under the couch cushions , dusted it at all doorways and rubbed it on the dogs too. Washed all our bedding (again) and vacuumed..then redid it 2 weeks later.  3 months of buying and trying expensive flea control stuff for our 2 dogs did nothing.  DE did the trick PLUS killed fire ants in our back yard and the roaches in the pantry.  I still have a couple of smaller / new fire ant mounds to get to but it has been raining off and on all week now and it only works when it is dry.
