What is Parastar Plus for Dogs?

Parastar Plus is a topical flea, tick, mite and lice treatment developed for dogs. The waterproof solution contains two active ingredients that begin to kill adult fleas, disease-spreading ticks, and chewing lice within 1 hour of application. It also controls mites that may cause sarcoptic mange. The solution continues to prevent infestations for one full month. The easy to use applicator is applied to a single spot to provide flea and tick protection. Gentle enough for use on puppies twelve weeks of age or older.


Dogs (12 weeks of age over 4 lbs)

  • Begins killing adult fleas and ticks within 1 hour
  • Kills adult fleas, ticks and chewing lice for up to 30 days
  • Controls mites that may cause Sarcoptic mange
  • Waterproof topical solution
  • Easy to use single spot application
  • Approved for dogs and puppies 12 weeks of age and over 4 lbs
How it Works:

Parastar Plus contains two fast-acting insecticides, fipronil and cyphenothrin, which start to kill fleas and ticks within 1 hour. The topical treatment is applied to the skin and spreads into the hair follicle, killing adult fleas before they lay eggs, ticks (brown dog tick, deer tick, American dog tick and lone star tick) that may transmit Lyme disease and Rocky Mountain spotted fever, and chewing lice for one month. In addition, it also controls mites that may cause sarcoptic mange.


Keep out of reach of children and pets. Consult a veterinarian before using on medicated, debilitated or aged dogs. Do not use on cats.

Brand Name:

Parastar™ Plus (fipronil/cyphenothrin)

Active Ingredient(s):

Fipronil (9.8%), Cyphenothrin (5.2%)

What is this product used for:

Parastar Plus contains two active ingredients, fipronil and cyphenothrin, which begin killing adult fleas and ticks (brown dog tick, deer tick, American dog tick and lone star tick) 1 hour after application and continue to kill for one full month. Parastar Plus also kills chewing lice and controls mites that may cause Sarcoptic mange, for one full month. Fipronil targets the nervous system, resulting in hyperexcitability and death. Cyphenothrin interferes with nerve cells, resulting in paralysis and death.


Parastar Plus is a non-prescription product.

How this product should be used:

Weigh your dog to be sure you are applying the correct dose for the weight of your dog. The solution should be applied monthly to a single spot between the dog's shoulder blades. Monthly application is recommended for control of flea, tick, chewing lice and mite infestations. Only one applicator per treatment is needed. Repeat application may be made if necessary, but do not apply more often than once every 30 days.

What are the side effects:

Sensitivities may rarely occur after using any pesticide product. Dogs may experience some temporary irritation at the site of product application. If signs persist, or become more severe within a few days of application, consult a veterinarian immediately. If your dog has an unusual reaction to the initial application, consult a veterinarian before repeating treatment. Certain medications can interact with pesticides.

What special precautions are there:

For external use only. For use on dogs and puppies only. Do not use on puppies less than twelve (12) weeks of age. Do not use on dogs or puppies under 4 lbs. Avoid contact with eyes, skin or clothing.

How should I store this product:

Store in original package in a cool, dark place away from children and pets.

How to Use
  • Remove one tube from the package.
  • Hold the tube with the narrow tip up and away from face and body. Snip off the end at the notches with scissors.
  • Turn the tube over and use the opened tip to part the dog's hair between the shoulder blades.
  • Firmly squeeze to apply all of the solution to the dog's skin in a single spot on the back.

Apply year round every 30 days for maximum flea and tick protection.

Parastar Plus for Dogs is rated 2.9 out of 5 by 29.
Rated 5 out of 5 by from I'm the PROUD owner of 5 Chihuahuas, I've been using this Prouduct (Parastar Plus) for over a year now, I live on 21 Acres of Wooded Property, I leave my dogs out & they go wandering, exploring in the Woods. Parastar Plus is a Life Saver in my Eyes. No Fleas or Ticks are brought into my house from any of my Dogs. I never have to be picking any fleas or ticks off of their coats either. I'm a very happy customer

Rated 5 out of 5 by from We've been using Parastar for 3 months and not a single flea or tick! We are very happy with it!

Rated 1 out of 5 by from Forget it! I purchased three months of this product for my dog. It failed the third month, dog infested with fleas, cat got them too! So far we have spent several hundred dollars on vet visits and product to rid the house of them. Spend the money and get Frontline.

Rated 5 out of 5 by from Keeps the ticks away I've been using parstar and it keeps the ticks away when we hike ! I love it

Rated 5 out of 5 by from works great we've used this product for 3 years now and have never had a tick. never! and we live in a wooded area with LOTS of deer that come thru our yard. Like I said, not 1 tick :)

Rated 5 out of 5 by from Excellent product for ticks I live in an area that is surrounded by woods. Every time my dogs wander into the woods they come back out with a tick or three. Every since I started using Parastar Plus, I've found two ticks on my dogs and they were dead. I've tried every other product over the years and this was the only thing that works. I have to believe these other reviews are being planted. This stuff really does work and even with English Bulldog's skin issues, they have never developed a rash or irritation. And believe me, I've watched them closely.

Do I need to keep my dog out of water immediately before or after using?

Asked by: Anonymous
I usually wait a day or so to bath after use. I have bathed before use with no problems. Just make sure your dog is completely dry.

Parastar & Comfortis

I am having major flea problems and my vet is recommending Comfortis. Can continue using Parastar with the comfortis so I have tick prevention as well. I WILL NOT USE A COLLAR.
Asked by: Anonymous
Unless you're using Prastar for anything other than fleas, Parastar is completely ineffective for flea control. I'm changing to Sentinel, mainly because it has the highest rating. You're seriously wasting money on parastar.

What about use with Heartguard?

My Vet recommended this for my SHIH-TZU puppy after revolution. Not sure why, but also had the heartworm shot when I took him in to be fixed. Is not time yet, but the reviews I see seems bad. I live in the county where fleas and ticks are many. So I am wondering if there is something else safe for him that is more effective? I am not sure of PARA STAR PLUS since reveiws are bad. Help 2 weeks until he needs something. Thanks

Can I use paraguard with heartguard chewables?

Asked by: Anonymous
It is common to use a flea medication such as Parastar along with heartworm prevention. However, we always recommend checking with your veterinarian before starting your dog on any new medications to make sure it is the best choice.
