I am so sorry! I had this problem recently, and it took me four months to get on top of it. Here's what finally worked for me:

Confine the dogs to only one room of the house, and put the strongest flea poison you can find into their mouths. Only the prescription stuff works nowadays.

Vacuum everything, every single day, twice. Mop the floors with strong vinegar. Do this until there are no more fleas, which takes a while.

Wash all bedding every single day, because you are taking them into your bed. Wash your slippers. Take your clothes off outside of the bedroom, and don't wear anything from the bedroom outside of it. You need to get at least one room that is flea free or you will go mad.

Treat all rugs or carpets with a mixture of table salt and diatomaceous earth. (Thank you @prydefolz for the salt tip!) Use a scrub brush to work it into the rugs and carpets. Roll up area rugs that you can't put in the washing machine, and wrap them in plastic wrap. Just leave those for a few weeks, then unroll, vacuum, and do it again. For wall to wall, put that stuff on, leave it overnight, vacuum carefully, every inch, and dust them again. Do this every day for a couple weeks.

Clean all dog bedding every single day and put the salt DE on those too.

I wouldn't let the dogs outside off leash for a good while, only on leash walking on sidewalks.

It sucks, I know, but it worked for me.
