Vacuum cleaner, some powder that does not harm the cats.

If you Frontline or Advantage drops at back of neck, you should not
really do it again.  Hartz flea drops available at Petco and pet stores,
drug stores is pestiside...it will most likely not work and put cat into
seizures.

As an effective treatment in conjunction with non-seizure flea drops,
try using a light flea trap.  Yes..these are remarkabley effective
at catching those other fleas.

Call your vet before you treat your cats again.  It is important to learn
what product was used and how long the interval should be between treatment.
For example, Advantage and Frontline are both excellent products -- but they
should be applied on schedule (or, at least, *no more often than
recommended*).  Do not use over-the-counter products.  In particular, *do
not use Hartz* -- there have been numerous reports of severe side-effects,
including some deaths.

As others have said, you will need to treat the house, cat bedding, etc.
Again, please ask your vet for recommendations.  Be sure to get some of the
flea powder into the edges of carpets and into little cracks that you may be
able to see in floorboards.  Vacuum thoroughly and frequently, and be sure
to vacuum chair/sofa cushions (and underneath them).  Empty the vacuum
cannister or remove the bag after *each* vacuuming while fleas are still
active; dispose of the waste outside your house.  Place several cut-up
pieces of a flea collar in the vacuum bag or cannister after it has been
emptied, in case any flea eggs have been retained and are "just waiting to
hatch."  It would be a good idea to treat the *exterior* of your house, too,
beginning at the foundation and moving out as far as possible.  A granular
product spread with a lawn spreader is easy to use, but you will need to be
cautious if dogs or other cats can get to that area.  I have probably made
this sound more difficult than it really is.  The point is, you will need to
be aggressive for awhile if you want to eliminate the problem.

It is not unusual to see fleas even after the cats have been treated.  My
vet once referred to flea eggs as "timed-release eggs" because they hatch at
such a variety of intervals.  Therefore, you may need to treat your cat for
a few months.  It is not unusual to find fleas even if your cat is an
indoor-only cat.  Fleas can be "imported" on your shoes (which is why I
suggested treating the perimeter outside your house) or other clothing, or
may even be unknowingly brought in by friends who have cats with fleas.
