Protecting your furry companion from fleas is crucial for their health and well-being. Fleas can cause intense itching, allergic reactions, and transmit diseases. Many pet owners rely on preventative treatments like Seresto collars to keep their dogs flea-free. However, a common question arises: Does Seresto kill fleas already on a dog?
Does Seresto Kill Fleas Already On Dog?
Seresto collars are popular for their long-lasting flea and tick protection. They contain two active ingredients, imidacloprid and flumethrin, which work together to repel and kill these parasites. Understanding how Seresto works and its effectiveness against existing infestations is essential for making informed decisions about your dog’s flea control.
How Seresto Works
Seresto collars release the active ingredients gradually over time, creating a protective barrier around your dog. Imidacloprid acts as a neurotoxin, disrupting the nervous system of fleas and ticks, while flumethrin repels and kills them on contact.
Effectiveness Against Existing Infestations
While Seresto collars are highly effective at preventing flea infestations, they may not immediately kill all fleas already present on your dog. The collar’s active ingredients work best as a preventative measure, gradually eliminating fleas over time. It may take a few days for Seresto to fully control an existing infestation.

How Seresto Works
Seresto collars contain two active ingredients: imidacloprid and flumethrin. These ingredients are released slowly from the collar and spread over the dog’s skin and fur. Imidacloprid is a neurotoxin that kills fleas on contact, while flumethrin repels ticks and kills fleas that bite the dog.
Does Seresto Kill Existing Fleas?
While Seresto is highly effective at preventing flea infestations, it’s not designed to immediately kill fleas that are already on your dog. The active ingredients need time to spread throughout the dog’s coat and come into contact with the fleas.
What to Do About Existing Fleas
If your dog already has fleas, you’ll need to take additional steps to get rid of them. Here are some options:
- Flea Shampoo: Use a flea shampoo specifically designed for dogs to kill existing fleas on contact.
- Flea Comb: Use a fine-toothed flea comb to manually remove fleas and their eggs from your dog’s fur.
- Oral Flea Medication: Talk to your veterinarian about oral flea medication that can kill adult fleas quickly.
Prevention is Key
The best way to deal with fleas is to prevent them in the first place. Seresto collars are a great option for long-lasting flea protection. (See Also: Don Cherry And Dog)
