Stronghold provides one of the most complete parasite treatments available in one easy spot-on application. The contents of one pipette are emptied onto the skin of the back of the neck once a month. The active ingredient is absorbed through the skin and for 1 month it will kill fleas, lice, worms and mites wherever they are, either inside, or on the surface of, the body. In areas where heartworm is found, Stronghold prevents this too, which is important for dogs and cats traveling to Europe on the Pet Travel Scheme.
