Sodium tetraborate, commonly known as borax, is a naturally occurring mineral compound consisting of sodium, boron, oxygen and water. Borax has many household uses, including cleaning laundry, removing stains from metal and softening hard water.

Crumple a piece of newspaper and stuff it inside the lid of the jar to help the lid keep its shape. Place the lid on the ground and punch approximately a dozen holes through the lid with the hammer and nail.
Fill the jar with borax and attach the lid. Sprinkle the borax, by turning the jar upside-down, anywhere in your home you've seen fleas. Be sure to thoroughly dust any carpeted areas and upholstered furniture as well as any cracks and crevices where fleas can hide. Sprinkle borax around the exterior sides of the house, including porch areas, creating a perimeter barrier against fleas.
Vacuum all areas treated with borax. Dispose of the vacuum bags by tightly sealing the vacuum bag inside of a plastic trash bag.
