How often do I treat to control fleas inside the house and yard?
To control a serious flea infestation indoors and outdoors, repeat treatment every 2 – 3 weeks for at least 6 weeks. Once the fleas are under control, maintenance requires treatment every 4 – 6 weeks thereafter. At the same time you’re treating the house and yard, use flea treatment such as Frontline or Advantage or Comfortis on the pet.
