Active ingredients

On top of the stylish appearance, the collar is formulated with active ingredients to repel pests such as lice, fleas, and ticks from latching on to your dog’s skin and hair. The Seresto dog collar has two main ingredients that are actively protecting your dog from unwanted pests.

The 10% (100 mg/g) Imidacloprid and 4% (45 mg/g) Flumethrin are the two active ingredients included in the Seresto dog collar to fight fleas and ticks.

These two ingredients have been scientifically researched to ensure that the perfect levels of Imidacloprid and Flumethrin are present in the dog collar.

These levels ensure that the dog collar protects from fleas and ticks for up to eight months, while also protecting your dog’s skin and fur. The slow-release and spread of the two active compounds provide unrivaled long-term protection.

The combination of Flumethrin and Imidacloprid prevents ticks of all sizes and ages and will also combat flea infestations, killing fleas at any point in their life cycle.

If you are noticing that your dog is itching or exposed to a tick, it is a sign that the eight-month effective period of the dog collar is up. Be sure to keep a good record of what date you put the collar on your dog to be ready with the next collar after the eight months.


One of the most recently discovered compounds to protect pets from pests and illnesses is Imidacloprid. It includes traces of insecticide for safe application on the skin and fur of dogs and cats. It is a proven compound that can reduce flea and tick presence by 90% or more within a matter of days.

The chemical compound is especially effective at fighting and killing:

  • Fleas
  • Ticks
  • Lice

The qualities of Imidacloprid have been engineered to be effective against the nicotinic receptors of insects while remaining safe for use on mammals. The chemical compound of Imidacloprid is a fast-acting lethal chemical to insect nervous systems. There is a high toxicity to insects, while specifically developed to be extremely low in toxicity to mammals, such as dogs and cats.

The compound Imidacloprid was designed specifically to prevent fleas, ticks, and other pests from bothering your dogs and pets. Imidacloprid has grown in popularity in the veterinary field and has been included in many modern medicines for house pets and larger livestock. Imidacloprid has even been implemented in food production to prevent insects from invading fresh foods.

Along with the safety of your dog, the chemical compound of Imidacloprid and Flumethrin are both safe for human contact. This means that when the chemicals begin to spread across the surface of your dog’s skin and hair, it is still safe to hug, cuddle, and sleep with your dog.

Imidacloprid in the collar is designed to release gradually, contributing to the eight months of effectiveness of these collars. Combined with some of the passive ingredients and the additional leading active ingredient, Flumethrin, provides your dog with an invisible coating that will gradually span across their entire body, protecting them from pests and invaders.


While the effective compound Imidacloprid has been a more recent discovery in veterinary medicine, Flumethrin is a compound that has been improved upon for many years. With long-standing use as a pyrethroid insecticide, Flumethrin is a proven compound to prevent ticks, fleas, or lice from mammals.

Flumethrin is very safe for use on mammals and pets, used in a range of household pet medications as well as for larger mammal preventative medicines (cows, horses, livestock, etc.).

Flumethrin works alongside the other active ingredient, Imidacloprid, to provide your dog with full-body protection against pests. The combination of the two active ingredients has proven especially effective at quickly eradicating pests from the surface of animal skin and preventing future invasions. Along with these preventative steps, Flumethrin can help prevent blood-borne diseases that come from pests, providing much more detailed protection of your pet’s health and safety.

The active ingredients of Imidacloprid and Flumethrin have been paired in Seresto’s groundbreaking dog collar to prevent fleas and ticks. Two GCP European clinical trials show that the combination of Flumethrin and Imidacloprid in the Seresto dog collar reduced tick exposure by around 90% and flea exposure to about 95%. These trials greatly supported the claims that the dog collars are effective for seven to eight months at a time, providing constant active defense. Flumethrin is designed to slowly spread across the skin and hair of animals over time to prevent infestations or kill pests on contact.

The combination of the two active compounds is unique to the Seresto dog collar, offering the longest-lasting protection of a single repellent treatment. The presence of Flumethrin and Imidacloprid on your dog’s skin and fur will ensure that ticks and fleas will be killed within 12 hours of contact.

Vs Other Brands

Alternatives to the Seresto dog collar repellent are topical or chewable methods. While these alternative sources offer some protection for your dog there are many downsides.

Seresto has developed pet collar that provides the longest lasting coverage of a single application. The dog and cat collar design means that your pet does not have to have sticky, greasy hair and skin from topical application or go through stomach and digestive complications that come from chewable styles.

Seresto features active compounds that protect your dog and cat from ticks and fleas, with additional benefits to combating lice. Pets enjoy the outdoors; however, they are easy targets for pests. Ticks and fleas hide in spots waiting for dogs to latch on to. The proven flea and tick repellent formula ensures that your dog can enjoy the outdoors without the worry of becoming host to these tiny pests.
