What is Seresto?

Seresto are the collars that kill blood-sucking insects thanks to the presence of two active ingredients in their composition. These are the substances imidacloprid and flumethrin, which are “imprinted” in the plastic base of the collar and are released from it in microscopic doses over several months, getting into the hair and skin of the animal.

The dosage is calculated perfectly: such an amount is not capable of harming a dog and a cat, during the entire time the accessory is used, the pet will be healthy, cheerful and happy. But fleas will fully experience the deadly power of Seresto.

Furthermore! The Seresto collar is able to kill fleas at all stages of their development – from larva to adult, and parasites do not adapt to its action. Not after a month, not after six months, it does not lose effectiveness!

The product is also safe for animals. Imidacloprid and flumethrin have long been widely used in parasite control, have a reputation for being low risk, and are often found in flea and tick control products.

Why Seresto?

The advantages of Seresto over analogues are undeniable; it is no coincidence that more and more responsible pet owners are choosing in its favour:

  • Begins to act immediately. There is no need to wait until fleas begin to bite the animal, as it occurs with drugs for internal use.
  • Protects the health of four-legged animals. The exact dosage and natural origin of the flea poisoning ingredients are safe for the animal.
  • Does not require extra efforts. You don’t need to bathe your dog to put the collar on it and kill fleas.
  • Does not frighten the animal and does not irritate it with strong odours, which often happens when spraying wool.
  • Costs little. No need to spend huge sums on ultrasonic collars that expel fleas with sounds of a special frequency.

How does Seresto work against fleas and ticks?

Despite the fact that outwardly the Seresto flea and tick collar looks like an ordinary strip of plastic, it is a polymer matrix, which contains high concentrations of substances that kill ticks and fleas.

Take the collar from the packaging, remove the plastic connectors from the inside, put on the animal and fasten it with a simple two-loop system. All you have to do after that is to make sure it is not too tight and the animal can breathe and swallow freely. It is especially true for puppies that grow very quickly! It is likely that after a couple of weeks Seresto will begin to press it, and the collar will have to be loosened.

The active components of the mixture will slowly penetrate into the hair and kill larvae, fleas, ticks and other parasites, without requiring any additional actions from the owners. If you need guaranteed protection against bites, scratches and diseases transmitted by blood-sucking insects, Seresto are the best choice!
