thanks for the anti flea tip.Here's another reason. If your house gets fleas brought in by pets, heavily sprinkle salt over your carpets and rugs and allow to set for as long as you can stand to walk on it. Try for at least 24 hours. The salt crystals desiccate the eggs the fleas have laid as well as the sharp crystals slice into the bug's body and causes it to dry out and die. Vacuum up well afterwards and repeat as needed. The bad thing is that your floors are going to feel damp because of the salt drawing the moisture, so just run a fan or two in the room.
