A shallow bowl of water with a few drops of cooking oil
will work.
Just add a night light above it. Ground fault might be a
good idea !

i used dish soap in the water when i got a flea infestation from
sitting my brother's dog... you just need something to break the
surface tension of the water & soapy water is easier to clean up
after than oily water if you spill any.
i also had pretty good luck treating rugs & soft furniture with
baking soda to help dry up the eggs & larvae (which feed on dust
& have a 5-10 day hatch cycle depending on weather. vacuum a lot
& make sure to empty the bag into a sealed bag outside. or burn
it. or put 1" pieces of flea collar into the bags. do NOT put
them on the animals!).
now i keep the cats & dogs on Advantage/Frontline...
