What Customers Are Saying

The product is effective at quickly killing adult fleas, with many customers reporting visible results within hours of administration. It is easy to give to pets, either directly or hidden in treats. However, it is a short-term solution and does not provide long-term flea prevention. To maintain flea-free pets, it is recommended to use the product in conjunction with a monthly flea prevention product. Overall, the product is a reliable option for quickly eliminating acute flea problems, though a few customers had mixed results or experienced side effects.

Fleas

Would Recommend

It’s killing the fleas would be better if it were chewable. Beef or bacon flavored. Would make it easier use

Worked on the first dose

Worked on the first dose. All those fleas seem to have disappeared off of my dogs and cats . I did vacuum everyday and give them baths but I think the Clincher was Capstar.

Amazing stuff

Would Recommend

This solved problems quickly. After a very dry summer, the fleas were horrible. My stepbrother brought their farm dog, which was covered in fleas. We ended up with an infestation. They were even biting us. I started treating the house with as many things as I could safely around a new puppy thankfully, I was able to give this to the puppy and to my senior. It took me a little over a month and a half. Between the collar, the pills and the drops on the back of the neck we finally have this fully ...

Zero stars wasn’t an option. Worthless product. Total waste of money.

Love them but they are becoming too expensive

Would Recommend

I was going crazy trying to find something that wasn't as expensive as the veterinarian. I have multiple fur babies and have to buy 8 packs at a time and it has been really convenient and affordable but now the prices are going up aggressively and now I feel anxiety that I'm not going to be able to continue using it.... praying they lower them so that I can afford to keep them.
