    Protect. Prevent. UltraGuard™.

    • The Hartz UltraGuard Cause

      • We are committed to providing the latest science to safely and effectively eliminate common parasites —including fleas, ticks and mosquitoes — and prevent them from biting or infesting pets and their surroundings.

      • We believe in affordable pest prevention for every pet. That is why Hartz® UltraGuard™ Flea & Tick products are broadly available in your local stores. Convenience and affordability with uncompromised efficacy and safety is our ongoing mission.

      • We recommend an integrated and complete approach to pest management. Our expertise in parasite protection ranges from on pet topical drops, shampoos, and collars to in home sprays, carpet powders, full room foggers and in yard sprays. Treating the whole problem is key to a pest-free environment.

      • At Hartz, we are committed to providing you with the necessary information to make educated, objective decisions about pest treatment products for your pet.

    • The Hartz UltraGuard Safety and Efficacy Pledge

      We hold our products to the strictest efficacy and safety standards by the Federal Environmental Protection Agency (EPA). In fact, all Hartz® UltraGuard™ products are held to the same high testing standards as products that are purchased from veterinarians.

      We will continue to work closely with the EPA and state environmental protection agencies to ensure that we deliver products that are not only safe and effective for our pets, but also friendly to our environment.
