The companies that do this type of treatment recommend to not vacuum for at least 2 weeks once the product is applied. Subsequent vacuuming will remove some powder, but also tends to reactivate the left over product. After 3-4 vacuuming's, it pretty much all gone and needs to be reapplied. Control takes up to 6 weeks, because it only kills the flea larvae. It does not kill the adults.
Once it's applied, you use a carpet rake to rake it into the carpet and then you leave it alone. Vacuuming before you do this is highly recommended, since you can't vacuum for a while.
