My cat brought fleas on my bed, how can I get rid of them!?

I just found a stray kitten, and I decided to adopt it. It's adorable but before I could get it treated for fleas, it somehow managed to get a couple on my bed! It's the only place Nyx has been in the whole apartment. How do I manage to get rid of the little buggers?? I've taken all of the sheets and pillowcases off and thrown them in the wash in hot cycle. Then I took the mattress and rubbed it down with Lysol clothes along with the pillows. Then I took all of my clothes and put them through the hot cycle also. The kitten is now completely treated and flea-free! Any extra measures I can take to get rid of them???
