If i rub my hardwood floors down with bleach water will that kill fleas?

No. If you don't get the problem fixed the dog or cat can accidentally eat a flea in it's water biting itself ect. And cause it to get tape worms and then the worms can come out the butt and break off larva and if you have a cut go into you wound and or a flea jump into your food or glass of wAter and you could get them. Go to the vet and get revolution and you'll be good to go if you start seeing your dog rubb butt on floor look at it and give me best answr
