Bio Spot Flea & Tick Repellent for Puppies, 16 oz.

• Kills and Repels Fleas & Ticks (including those carrying Lyme Disease)
• Kills Flea Eggs for 28 Days
• Fast Acting Formula

DO NOT USE ON CATS. DO NOT USE ON PUPPIES UNDER 12 WEEKS OF AGE. A light, even coverage of the hair coat will provide effective flea control. Do not allow spray from application or damp animal to come into contact with painted or finished surfaces, including wood floors/furniture, leather/vinyl materials, or other surfaces of concern. Leaving the eyes, nose, and mouth exposed, treat puppies weighing less than 3 lbs. by wrapping the animal in a towel which has been lightly sprayed with Bio Spot® Flea & Tick Repellent for Puppies. Keep the animal wrapped for 5 to 10 minutes, or lightly spray a brush or cotton ball and work thoroughly into the hair coat. Adult fleas may then be removed from the coat by picking or combing. Puppies over 3 lbs. may be treated with 1 to 2 squeezes of the trigger sprayer per pound of body weight. Reapply every 28 days, for continuous home flea infestation prevention.
