Fleas are small black insects that do not have any wings. It is easy for outdoor cats and dogs to pick up fleas during the spring and summer months. Once this happens, the fleas quickly multiply and take over your home. Because fleas are so tiny, many people have trouble spotting them. A pure white piece of paper can show that fleas exist in your home, and then you can work on getting rid of them.
Lay a sheet of white paper down underneath any outlets in your home.
Mix two drops of dish soap with one cup of warm water. Pour this mixture into a bowl.
Set the bowl on top of the white sheet of paper.
Plug the night light in and turn it on. The light will attract the fleas. When they hop on the paper you will be able to see them. Then they will hop toward the light into the bowl of soapy water. They will drown.
Empty your bowl of soapy water daily, and replace it with fresh soapy water. Do this until you no longer see fleas on the white paper or in the bowl.
