Air out the room well (open the windows to outdoors) for a few days and that should be fine. Dont believe products that say a couple hours is sufficient.
I highly recommend NOT spraying your bed, for your own sake - certainly you should have fresh unsprayed sheets.
To rid a house of fleas you need thorough daily vacuuming, move out all furniture and get under and behind everything and along all edges, daily. Vaccume not just the carpets but also the furniture.
Use the liquid flea killer (like Frontline or Advantage) on the neck of your pets, as this will not only get rid of fleas but keep them from coming back for at least three weeks. You'll need several treatments since there are also likely flea eggs in the carpet and such. Use a Flea comb daily for 3 weeks until the liquid flea killer on the pets and the vaccuming have done the job (you'll no longer find evidence of fleas on the pets).
