Thorough vamuuming should be done right before you do any home treatment
. This will stimulate the fleas developing in cocoons to emerge onto the carpet so that they can be quickly killed when you treat the carpeting. There should be no problem if you vacuum after treating your home, as long as the product is first left to dry completely. If you still see fleas after the treatment, we encourage you to vacuum your home more frequently, followed by a re-treatment after 2 weeks.
