PS — knowing a fleas life cycle helps in going to battle with them.. The flea lays eggs and the eggs hatch (and look like tiny worms). The worms (called the larval stage) develop a cocoon type barrier (called the pupal stage) where they transform into an adult flea (like a caterpillar becoming a butterfly). Once the transformation is done they emerge as what we know to be a flea. Most products will not kill a flea when they are in the pupal stage. And, the flea can stay in the pupal stage til the right conditions for emerging are present. IF you vacuum well, launder items you can that have been slept on you can eliminate a good deal of the fleas in the pupal stage. The pupal stage is also why you want to rebath, reapply DE and relaunder at least once after a few weeks and then several times more if necessary.

There are other natural things you can try if necessary. You can also try a different flea product but I would definitley wait until the body has been able to eliminate the Frontline. Applying too many chemicals weakens the immune system making it even harder to fight off fleas etc.
