Putting the bedding in black plastic bags, and then setting them outside in the summer sun for a few days should kill any fleas. See At what temperature do fleas die.

I don’t think this will help on its own – starving fleas can take a really long time. I would recommend (if you don’t want to wash the pet bedding for whatever reason – although this seems to be the most effective way of ridding the bedding of fleas) to chuck the bagged bedding into your freezer for at least a couple days.
Cover the bed in thick layer of dermaceous earth so you can see the white powder for up to three days, vacuums and do it again.
