Capstar Green an efficient, single, fast-acting dose that kills adult fleas on your dog. If your dog gets re-infested with fleas, you can safely give another dose as often as once per day. To administer Capstar tablets, place the pill directly in your pet's mouth, or hide it in food. If you choose to hide the tablet in food, watch closely to make sure your pet swallows the pill. If you are not sure that your pet swallowed the pill, it is safe to administer a second pill.

We recommend you follow up Capstar treatment with a monthly flea control product such as Frontline Plus and keep Capstar on hand for the times when there is a visible flea re-infestation.

We have had a terrible time with fleas since moving down from a cold climate state. My dogs suffers so badly. Since using the Capstar tablets fleas no longer hang around our home!! They work fast!!

Capstar works great and doesn't cause my dogs any problem. He does scratch wildly for about an hour after as the fleas are responding to the pill.

Works Temporarily
April 2, 2017
The product does work but for a very short time. When I purchased the product I had given my animals a bath with the appropriate shampoo, treated and vacuumed all cloth surfaces and sprayed those surfaces. I then gave this product to the my animals. It worked for a day, had to give additional pills as the box indicated. For a product that is supposed to be given monthly and yet it is gone in less than a month does not work as stated.

A great product

Capstar has always worked very well for all my pets both cats and dogs. It does continue to work for 24 hours which makes it an excellent choice for ridding your pets of these annoying fleas. Between Capstar and frontline plus my pets have a better life.

Best Flea Killer
October 7, 2015
I used Capstar for my "new" 110lb German Shepherd. Dog was constantly scratching and biting them. I use a small portion of slice cheese and smush the cheese around the pill so the dog readily accepts the pill. Not sure if the dog will eat it otherwise, we just do this with all meds. Capstar kills fleas quickly. I do followup with Frontline Plus but Frontline Plus alone hasn't worked that well when we've brought in new pets. Highly recommend a few doses of Capstar to eliminate fleas.

This is a great product to use in between the monthly product you use on your pets. A lot of times we see our pets getting adult fleas before the 30 days are past. This can be used to keep new flea infestation in check until it is safe to use the monthly product. It has a longer affect on our cats then the dogs but it does calm down the problem. I saw the same product at a pet store and their price was $44.

Fast Acting, Great for serious flea infestations
April 17, 2015
I have used this on my cats and dogs for years. When fleas infest your home I highly recommend this product. Use a quality topical treatment such as Frontline Plus, Also treat your yard, vacuum all floors, shampoo carpets if possible and spray carpets with the name brand bug spray the kills both fleas and hatching eggs. When I had to do this one year, they were under control quickly. Be thorough. Clean all pet bedding as well. But to ease your pets scratching and misery, definitely use this product. I keep it on hand at all times.

Works quickly and efficiently
April 15, 2015
This was the first year in 14 years that my dog got fleas and oh my gosh did he get fleas. I didn't even realize he had fleas until he was horribly infested. We sprayed him with the Adams spray, bathed him in the Adams bath and treated him with these pills. It was slow going until I gave him these pills and then they completely disappeared. I've been working on my carpet. Fleas are so gross I just want to get rid of my carpet now. These pills work and work quickly and efficiently. I would recommend these even though they are quite expensive. They only work for 24 hours. I gave my dog one for 2 days then one every other day for a week. Will definitely use these again if needed.

It works!
September 22, 2014
This has been a wonderful discovery for me. It has been a terrible summer for fleas and my long-haired dog has been really suffering, even with my applying Frontline every month. I give him a Capstar every 5-7 days and it definitely gives him some relief. I was a little concerned the first time he took one, as I didn't read the directions advising that the pet may experience even more itching for the first few hours as the fleas die. But after that's over you can really tell when they've been eliminated!

If you have ever noticed 1 flea on your dog even when on flea meds, this product is great. Kills all live fleas within an hour and can be used daily to break the flea cycle!

Capstar really works
June 19, 2014
Capstar works wonders when fleas get the best of our dog and cats. It starts working within hours, and we usually do 2 doses, a day apart. It really works! We've been using it for several years.

Love it

This product is great at keeping the fleas at bay.
Use it on both my cat & dog.

Also works well with Program monthly product.

Sometimes, after playing with a pack of other dogs (dog park or daycare) the dogs return home scratching. Even though the dogs are on flea/tick prevention monthly meds, I've found Capstar helpful after playdates. Capstar works quickly and offers a backup to the monthly meds.

Works Well
January 31, 2014
This product worked well, we had a serious infestation and Advantix just didn't seem to be able to knock the fleas off. Combined the Capstar with the Advantix and this seemed to do the trick.

Kills fleas almost instantly, providing much needed relief to your dog. Always continue with your chosen monthly flea control, too, but Capstar is great when you're dealing with the inevitable infestation that can occur in the height of flea season. Gave him one every week for 4 weeks and our dog and home are now totally flea free. Safe and effective with no side effects whatsoever. Highly recommend Capstar for all your pets as well as the cost savings on Entirely Pets...a reputable American company.

Capstar is a good product and kills any flea on my dogs. We place a pill in dog food, boiled eggs, about anything and it's down and working.
