FRONTLINE® Plus can be safely used from 8 weeks on and combines fipronil with (S)-methoprene to get rid of unwanted inhabitants on your pet’s skin. The product spreads over your dog’s whole body within 24 hours, bringing relief by killing all fleas and most disease-causing ticks it comes into contact with. The fipronil is the active ingredient causing the insects to die, whereas the (S)-methoprene interferes with egg production, preventing flea eggs to hatch and it inhibits larval development. This means no more flea breeding, bringing an end to its life cycle. Use the product monthly to ensure your pet’s continuous comfort and a carefree and infestation free existence. PLEASE NOTE: Do not bathe or shampoo your pet for three days before or after the product has been used.
