I expect she'll scratch that flea out if its bothering her enough, but
tomorrow you need to get her some treatment that treats the whole body, not
just her ears (systemic treatment helps with ear mite too). Also consider
that a flea infestation is not just on the animal but in your soft
furnishings, and on any other animals so treat them too.
When mine were having trouble with ear mites the vet prescribed them
Stronghold (I'm in England so it may not be available/called this where you
are) which contains something called Selamectin. The box says 'for cats &
dogs weighing 2.5 kg or less' and 'spot-on solution for internal and
external parasites'. It's drops that you put onto the skin at the back of
the neck and it absorbs through the skin.
I was advised to use one 0.25ml tube across 4 ferrets - so if you opt for
this sort of stuff you only need a very small amount per animal, and it
protects for a month - enough to break the parasite life cycle.

Never thought of trying a systemic. Sounds like a good tip.
For what it's worth I sometimes spray their home and bedding with Frontline
(Flea and tick spray). Then when they kip down it gets into their fur. If
you use straw or hay, shove it in a bin liner, spray it and give it a good
shake so it gets coated.
