HAZARDS TO HUMANS: Repeated exposure to etofenprox can cause skin irritation. HAZARDS TO ANIMALS: For External Use on Cats only. DO NOT USE ON KITTENS LESS THAN 12 WEEKS OLD. Consult a veterinarian before using this product on debilitated, aged, pregnant or nursing animals. Certain medications can interact with pesticides. Consult a veterinarian before using on medicated animals. Sensitivities may occur after using any pesticide product for pets. If signs of sensitivity occur, bathe your pet with mild soap and rinse with large amounts of water. If signs continue, consult a veterinarian immediately.

Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

    Works great

    By Missy on Feb 7, 2021

    Precious is my indoor 19 yr old cat. He only goes out on the balcony, but Missy who is my little barker is in and out a lot. I protect both with Hertz and have never had a problem with ticks or flea's in 19 year's. Great product

    Too Much Volume and Ineffective Compared to Other Products

    By Jenny on Oct 26, 2020

    I chose to try Hartz Ultraguard because it was much cheaper than the other flea & tick remedies. One plus: the dispenser cap was so much easier to use than other brands, just a twist and it's open. The minuses: the liquid dispensed was far more than other treatments, so it covered more than just the back of the neck, and was much easier for my cats to access and try to get off. Plus, it didn't get rid of the fleas! My cats' fleas did not decrease, and I ended up purchasing another product to take care of the problem.

    Even with our cat being strictly an indoor cat, we find that a flea treatment is beneficial to avoid any possible infections from visiting friends and animals. Hartz Ultra Guard Pro Flea & Tick Treatments are easy to use and the results are very satisfactory.

    Wouldn't Recommend!

    By kandiego on Nov 8, 2019

    I have 3 indoor cats. This season they inexplicably got fleas from i don't know where. I tried this product and have been very disappointed. It did not kill a single flea! They are still biting and scratching. The smell is horrendous and totally freaked my cats out upon application! And it leaves a huge oily area that lasts forever at the application site. Will never buy again! Now looking for another brand to buy to get rid of their fleas. Will definitely pay more attention to reviews this time around!
