Using borax is a effective and popular method of killing fleas because borax is odorless, readily available in powdered form and easy to use. As a natural derivative of boron, borax is far less toxic than many alternative flea control remedies. When fleas come into contact with the powder, they become extremely dehydrated as the sharp structure of borax shreds their insides.
Read the directions for use and familiarize yourself with the safety precautions before using borax inside your home.
Vacuum the carpets inside your home thoroughly. Sprinkle the borax, in generous amount, in areas of flea infestation. Work the powder deep into the carpets with a stiff brush.
Leave the borax on your carpets for up to two days, if possible; leave it for a minimum of six hours. Keep children and pets away from the treated areas during this time.
Vacuum the carpet thoroughly. Remove the vacuum bags, seal them and dispose of them in an outdoor trash can to keep all larvae and eggs well away from your home.
