Hi Emily,
Here are a couple of sites for natural flea control:

Advantage works pretty well.  Before it became available I used to
bathe the cat about once a month, which only temporarily reduced the
flea population.

My cats have used advantage for years without problems. Now there's another
topical product called Evolution that guards against fleas and ticks and
worms. My cats are on that now.

We use advantage exclusively on our bengals.  'Nuff said, hopefully.

My cats are indoor cats and don't normally get fleas, but once, at a time
when I was living in an apartment in which I shared a hallway with a
downstairs neighbor who had dogs and used to let them in the hallway to
let them out, the dogs got fleas--and I got fleas from passing through the
same hall as the dogs. As a result, I unwittingly brought them upstairs to
my cats and infested them, too. Argh! Never underestimate the power of
humans to help transmit fleas!

My downstairs neighbor took her dogs to the vet and got them put on
Advantage. I took my cats to the vet (only one of them, actually) and we
got Frontline. My neighbor never had flea problems with the dogs again,
and after the one course of treatment, I never had to treat my cats again
at all.

The good thing about it was that I was able to "flea-bomb" my bedroom, as
it were, without all the hassle of a real flea bomb, by simply allowing my
cats into it for a few days after I'd treated them. At the time, I hadn't
been letting them in there, and you know how cats are just dying to spend
time in a formerly forbidden place in the home, so when I changed the
rules and let them in, they spent tons of hours in there just lying around
during the day while I stayed outside. The end result was that the fleas
in my bedroom, seeing a fresh source of blood other than me, jumped onto
the cats immediately and died--not to mention that it broke the cycle of
the eggs, etc. I needed this to happen badly, as I was getting eaten alive
myself at night by fleas! I needed to get the fleas transferred to a
creature whose skin would kill them, not allow them to feast at will--and
allowing the cats in the bedroom worked like a charm. (I sometimes joke
that I was tempted to put the Frontline on myself, too!)

Other methods may be even less intrusive if you have concerns about the
chemicals--but I had no problem with using Frontline on my cats, and my
neighbor had no problem with Advantage on her dogs.

Advantage is extremely safe to use.  

This review should clear up any misinformation floating around about
the relative safety of veterinary insecticides currently on the
market.  Please note the comments regarding the safety of Fipronil
(Frontline), Imidacloprid (Advantage) and Selamectin (Revolution).
These insecticides are safe for use in mammals because the receptors
they act upon are either absent in mammals, configured differently in
mammals, or are not receptors that are found in great abundance in
mammals (as opposed to the receptors for the older, outdated
insecticides which tend to be less insect-specific).

Use advantage with peace of mind.  While some cats have an allergic
skin reaction to the carrier in the product, the active ingredient is
*extremely* safe.

Best of luck to you,
-L.
