To get rid of a flea infestation you have to treat the SOURCE, and the source of the fleas are not the ones that are on your pets!! Fleas live outdoors in your yard, and indoors in your carpet, bedding, and furniture!! Vacuum DAILY, perhaps putting a flea collar in your vacuum bag to help kill any fleas you may vacuum up. After vacuuming, DISPOSE OF THE BAG. Even if its not full do not let it sit around. Put it inside a trashbag, close it up tight, and throw it outside. I've heard ALL KINDS of trick that help repel fleas.. from putting a small dish of pine needles under your couches and such to some sort of salt that kills them.

There are lots of carpet powders you can buy. But don't sprinkle it on and vacuum it immediately up; sprinkle it on, LEAVE it on, and THEN vacuum everything up. This you should probably do one room at a time so if you have children or other pets they can't get into the powder.

And bomb and/or spray your yard very well!! I've also heard that planting Azalea bushes help repel fleas, too (I wouldn't know though since Jamie and Charlie ATE all of ours! )
