Foresto vs. Seresto: What’s the Difference?

As a pet expert, I often get asked about the best flea and tick prevention products for pets. Two names that frequently come up are Foresto and Seresto collars. You might be wondering, what's the difference? Are they essentially the same product with different names? Let’s delve into it.

Brand and Availability

Firstly, the names Foresto and Seresto often confuse pet owners because they refer to the same product but in different markets. Seresto is the brand name used in North America, while Foresto is the name used in Europe and other regions. So, if you see both names, don’t be alarmed; they are the same effective collar, just marketed differently.

Active Ingredients

Both Foresto and Seresto collars contain the same active ingredients: imidacloprid and flumethrin. Imidacloprid attacks fleas’ nervous systems, killing them before they can lay eggs. Flumethrin is a potent tick killer and repellent. This combination provides comprehensive protection against fleas and ticks for up to eight months.


Because they are the same product, Foresto and Seresto offer the same level of efficacy. They provide continuous protection, killing fleas and ticks on contact, meaning parasites don’t need to bite your pet to be affected. This reduces the risk of disease transmission and keeps your pets more comfortable.

Design and Features

The design of both collars is identical. They are odorless, non-greasy, and water-resistant, making them perfect for active pets who love to swim or roll in the mud. They also feature a quick-release mechanism for added safety, ensuring that if your pet gets caught, they can easily get free.

Usage and Application

Application of both Foresto and Seresto collars is straightforward. Simply place the collar around your pet’s neck, adjust for a snug fit, and you’re good to go. The collars gradually release their active ingredients over eight months, providing hassle-free protection without the need for monthly treatments.

Safety and Side Effects

Both collars are designed with safety in mind and have undergone rigorous testing. Side effects are rare but can include mild skin reactions in some pets. If you notice any adverse reactions, consult your vet immediately. The quick-release feature ensures that your pet remains safe if the collar gets caught on anything.

Price and Availability

Prices can vary depending on the region and retailer, but generally, both Foresto and Seresto collars offer excellent value given their long-lasting protection. Availability might differ based on where you are shopping. In North America, look for Seresto, while in Europe and other regions, you’ll find Foresto.


In essence, Foresto and Seresto collars are the same product, offering the same excellent protection against fleas and ticks. The choice between them simply depends on where you are located. Both provide a long-lasting, convenient, and effective solution to keep your pets safe and healthy.
