My ferret has fleas. Help ?

I have 2 cats and 2 ferrets. One of my ferrets,Fiona,who is sick with adrenal disease has fleas. Both the cats don't and we haven't seen any on Joe. Only fiona when we washed her the other day we had about five or six on her. Right away we washed both of them with flea shampoo, and heated up all of their bedding to kill fleas. I also cleaned the age and used a lemon, water, apple cider vinegar to clean the cage and lemon and water on them. The family only has one victim. Me. An that's b/c I slp in the same room. Since the fleas are only seen on Fiona,not bedding or even Joe. Will doing what I explained I did up there be enough to kill the invasion??
