Yes, Seresto does kill fleas already on your dog. This is because Seresto’s active ingredients – imidacloprid and flumethrin – are effective at killing both adult fleas and their eggs.

Seresto works by killing already-existing flea infestations within 24 hours and prevents further infestations from established flea populations for up to 8 months. It kills and repels ticks, such as deer ticks, American dog ticks, brown dog ticks, and lone star ticks for up to 8 months. In addition to this it also helps with the prevention of lice on dogs for up to 5 weeks after initial application.

If your pet has a bad flea infestation, you may also want to complement Seresto with a topical or oral protection that also helps disturb the existing flea cycle in order to speed its elimination faster than relying only on one product alone.

How does Seresto work?

Seresto is an effective flea and tick collar for dogs and cats. It uses a revolutionary technology called ‘microencapsulation’ to slowly release ingredients over a period of eight months, eliminating existing fleas and preventing future infestations.

The active ingredients in Seresto are imidacloprid and flumethrin. Imidacloprid is a neurotoxin that paralyzes the fleas, while flumethrin works as a repellent to keep new fleas away. These active ingredients are gradually released by the collar using microencapsulation technology, allowing your pet to have continual protection from fleas and ticks without needing monthly reapplication.

This breakthrough technology ensures that Seresto can protect your pet for up to 8 months, eliminating existing infestations as well as preventing new ones from recurring. So if you’re looking for an effective way to get rid of those pesky fleas, Seresto is definitely worth considering!

Are there any side effects?

The good news is that Seresto is a relatively safe flea and tick treatment for dogs. Most dog owners report very few if any side effects after using it.

However, there are some potential side effects to be aware of when giving your dog the Seresto collar. These include an occasional localized skin irritation around the collar area, as well as hair loss in areas with direct contact with the collar. Other rare reported side effects include vomiting, diarrhea, trembling, or increased salivation.

If you do observe any of these side effects, remove the collar and contact your vet right away. Generally speaking though, Seresto is considered to be a safe and effective way to kill fleas already on your dog while preventing future infestations.

Does Seresto prevent reinfestation?

The answer is yes! Seresto does kill fleas already on your dog’s fur and skin, but it also prevents reinfestation. How? Seresto uses two types of active ingredients: imidacloprid and flumethrin. Imidacloprid kills adult fleas while flumethrin works as a repellent to keep new fleas away.

With this “double dose” of protection, Seresto offers eight months of continuous relief from both existing pests and those that have yet to take up residence on your pup’s fur or skin. And with the easy-to-use collars, you won’t have to put in much effort – just snap it on and go!

Does Seresto kill other pests?

Yes, Seresto does kill other pests in addition to fleas on your dog. In fact, it’s formulated to control fleas, ticks, and lice. All three of these types of parasites can cause itching and discomfort for your pet, so protecting against all three is important.

Seresto’s main active ingredient is an insecticide that works to kill these parasites while they’re still in the larval stage. This means it can even kill parasites before they have a chance to attach themselves to your pup! In addition, Seresto also contains an insect growth regulator (IGR) that stops flea eggs from hatching into larvae and prevents adult fleas from reproducing. Together, this powerful combination kills existing pests while proactively blocking future infestations as well.

To sum up

While it can take a few days for full relief of existing flea infestations on your dog when using Seresto, the product offers protection that lasts up to 8 months against future infestations.
