Quickly Kills Fleas, Ticks, and Chewing Lice

This powerful formula kills up to 100 percent of existing fleas in the first 12 hours after application, and it continues to kill new fleas for at least one month afterward. FRONTLINE Plus prevents the development of new fleas by destroying flea eggs and larvae and by destroying adult fleas before they have a chance to lay eggs. FRONTLINE kills chewing lice and all four major ticks, including ticks that may carry Lyme disease, keeping both your pet and your family protected.

Waterproof Formula

Thanks to its waterproof formula, FRONTLINE Plus won't rinse off when you give your dog a bath or when your dog goes for a swim. The active ingredient in FRONTLINE, fipronil, is stored in the natural oils in your dog's coat, so your pet is sure to stay protected no matter how many puddles he or she tramps through.

Fipronil is a manufactured insecticide that works on a cellular level on adult fleas and ticks. It seeps into an insect's cells and blocks chlorine molecules from passing through. This stops the nervous system from working and paralyzes the insect.

Fipronil kills adult fleas and ticks on contact or when consumed, and it can be spread from one insect to another.


Because fipronil is so strong, it only needs to be applied once a month to continuously kill fleas and ticks. Once it is applied with an oily liquid to keep it on the skin of your dog, it slowly seeps into the hair follicles and oil glands where the fleas and ticks live.

Main Purpose

To kill adult fleas and ticks.


Methoprene is an insect growth regulator, which means it works by affecting the eggs and larvae of fleas. It interrupts normal levels of growth hormone, preventing a juvenile flea from growing and molting, leading to death.


Specifically designed to target developing larvae and eggs, methoprene prevents a flea population from increasing.

Main Purpose

To break the flea life cycle and stop further infestation.

Active Ingredients % by Weight
Fipronil 9.8%
(S)-Methoprene 8.8%
Inert Ingredients 81.4%
Total 100%

Some animals are sensitive or allergic to the ingredients in FRONTLINE, so be sure to watch for any signs of allergic reaction. If your pet shows signs of itching, restlessness, nausea, lethargy, or breathing difficulty, seek veterinary attention immediately.

Useful Information

How FRONTLINE Plus Works

Use FRONTLINE Plus for fast-acting, long-lasting flea and tick control. When you apply FRONTLINE, fipronil, the active ingredient, is stored in the oil glands under your pet's skin. It's then distributed continuously to the skin and hair of your pet through the hair follicles. This way, FRONTLINE provides waterproof, month-long protection against future pests while breaking down the flea and tick life cycles.

Simple Three-Step Application

Applying FRONTLINE Plus to your pet is an easy three-step process. First, remove the Frontline Plus applicator from the child-resistant package and cut or lift off the plastic tab to expose the foil and then peel the foil down. Next, hold the applicator upright and away from your face and body and snap off the tip. Finally, place the Frontline Plus applicator tip on the skin between your pet's shoulder blades and squeeze the applicator to apply the entire contents in a single spot onto your pet's skin.

To prevent harm to you and your pet, read the entire label and enclosed directions before each use. Follow all directions and precautionary statements carefully.


To prevent harm to you and your pet, read the entire label and enclosed directions before each use. Follow all directions and precautionary statements carefully. Always point the applicator away from your face, especially your eyes, and wash your hands thoroughly after application. USE ON DOGS ONLY. Do not use on rabbits or other animals.

Frontline Plus is a Must Have for Fleas and Ticks
I have been using Frontline Plus on our dogs for years. We have never had a Flea or Tick problem with our dogs. We start using it on
April 1 thru Nov. 1. Based on our positive results with this product I would not hesitate to recommend it.
We always purchase Frontline Plus from Entirely Pets. Their prices are by far the lowest. Their service is the best!!
Thank you Entirely Pets!!

This product works very well
I have been using Frontline Plus for about 10 years on my two terriers. We live in a rural area with a lot of deer and ticks. I also experienced a flea infestation when I first moved into our house. I got rid of the fleas with diligent effort, started using Frontline Plus on a regular 4 week schedule and have not seen one flea on our dogs, and maybe 2 ticks each in these 10 years.

Entirley Satisfied
We started using Frontline on our Bichon "Buddy" with great results when he was just a puppy. His vet talked me into trying an oral tablet but it made him sick and we went back to Frontline. He tolerates it well and has had no fleas or ticks in the almost five years we have had him. The most economical way to buy it is purchasing a years supply from Entirley Pets online.

Frontline plus vs pet armour
Frontline wins. We use frontline for protection against ticks. We have shorthaired dogs and found frontline stays on longer. Don't know why, maybe doesn't wash off as easily?

very disappointed
I have several dogs and each one without exception continues to have fleas after application. This product does not last 30 days as a matter of fact it is not even effective for one day. It is way over priced for what it claims to do. I called the help line and they were of no help either.
