Ecto Soothe 3X is the best all-round flea and tick shampoo we've used. Like many other products, it does an excellent job of killing fleas and ticks. Unlike others, it contains microencapsulated ingredients to alleviate skin irritation and allergy. These patented microcapsules (called Spherulites) slowly release glycerin and collodial oatmeal, moisturinzing and soothing the skin long after the shampoo has been rinsed away. Ecto soothe 3X is approved for puppies and kittens 12 weeks of age and older. Directions for use: Shake well before using. Apply product tothe back of the animal and massage well into the skin to obtain a good lathering of the entire body. Allow lather to remain in contact with the skin for at least 10 minutes. Rinse thoroughly with warm water and towel or blow dry. Do not repeat the treatment more frequently than once weekly. Active Ingredients: Pyre3thrins 0.15% Piperonyl Butoxide technical 1.50% n-Octyl bicycloheptane dicarboximide 0.50%
