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.
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.

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:
- 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.
- Hold the applicator upright and away from your face and body and snap off the tip.
- 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. 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.
