Fleas 😰

I have three dogs and three cats. A few months back I rescued four kittens and homed them all. Was pretty sure we were flea free until a few days ago...I noticed flea dirt on my one cats back (he’s bright white so easy to spot) checked them all and pulled a couple fleas off all three cats, and only one of my Australian Shepherd . Other two dogs are clear. Went to the vet and got frontline for the cats, bathed in dawn dish soap and the dogs have a flea bath scheduled for Wednesday at the groomer. I washed all my couch cushions , bedding , rugs etc. On high heat, I don’t have much carpet in my house except stairs that go to our basement so I carpet cleaned those. Swept and vacuumed the whole hose and then took my cross wave over the vinyl floor which is basically Emmy whole house. Any recommendations on anything else I should be doing ?
