We use Advantage and Advantage Kill Tix for Draker and he is flea and tick free all the time. And we go into the woods daily serveral times for runs and walks.

Advantage and Frontline are from the vet and can also be gotten online. The store bought flea preventatives are not effective at all. You are going to have to clean the house and the yard to get rid of them. Vaccuum the carpets and put the bag out in the sun for several hours and the throw the whole bag away!! You will also need to spray the yard with some strong professional stuff. Wash all bedding and clothes, etc...

Good luck!
