In the evening, pour about two cups of water in a glass pie
pan and then add two tablespoons of cooking oil on top of it.
Place this pie pan on the floor. I usually set it under my
kitchen table.
Take a crookneck lamp and shine the light right
on the pan. Make sure all the other lights in the house are
off. You will be amazed that fleas from all over the house
will come to the pan and drown. If you are really infested
with fleas, you may need to do this about three nights in a
row.
