Best all around product besides baking soda and vinegar in my house.  It is an excellent laundry and dishwasher booster as it helps soften the water, helps remove stains from clothes, decreases water spots and works as a great ant killer!  Simply mix with jelly or honey to create a loose paste and leave in their trail wherever you see them coming in.  They will swarm it and grub, (fight all instincts to bust out the flame throwers and send them to Hades,) let them eat to their hearts content.  They will take it back to their home and queen and share as they do and then the magic happens.  The Borax slowly poisons them and you never see them again!  After they are gone, I sprinkle a combination or cinnamon and cayenne pepper around the area they came in so they won't come back that way and voila!  No stinky pesticides!
