Ear mites are a common problem in pets, particularly cats and dogs. As a pet owner, it’s crucial to understand the treatments available to fight these mites. One of the popularly acclaimed solutions is Capstar. But the question arises, does Capstar kill ear mites?

What Are Ear Mites?

Before delving into the efficacy of Capstar, it’s only fair to understand what ear mites are. Ear mites are tiny, eight-legged parasites that feed on the wax and oils in a pet’s ear canal. Leading to inflammation and infection, these mites are a common cause of ear disease and infection in pets.

Signs of Ear Mite Infestation

Does your pet display excessive scratching on the ears? Does it have redness, swelling, or a dark discharge in the ear canal? These could be signs of an ear mite infestation, calling for immediate attention and treatment.

What Is Capstar?

Capstar (Nitenpyram) is a fast-acting oral treatment used in dogs and cats to kill fleas. Manufactured by Elanco, it begins working within 30 minutes of administration, and within 4 hours (for dogs) to 6 hours (for cats), nearly all adult fleas will be dead.

How Does Capstar Work?

Capstar contains the active ingredient Nitenpyram, an insecticide that affects the central nervous system of insects but has minimal effect on mammals. When a flea bites the pet after it has taken Capstar, it ingests Nitenpyram, which interferes with the flea’s neurotransmission, killing it rapidly.

Does Capstar Kill Ear Mites?

Now, coming back to the main question, does Capstar kill ear mites? Although Capstar is highly effective against fleas, unfortunately, it doesn’t have the same effect on ear mites. It’s primarily because Capstar, or Nitenpyram, is specifically designed to target fleas, not mites.

Effective Treatments for Ear Mites

While Capstar might not be your go-to solution for ear mites, several other treatments can help. Topical medications, like Fipronil, and acaricide ear drops or ointments are often recommended. Remember, though, to always consult with your vet before starting any treatment regimen.

Prevention is Better Than Cure

Preventing ear mite infestation is infinitely better than curing it. Regularly check your pet’s ears for any signs of mites, keep them clean, and make sure they have regular vet check-ups.

Are Ear Mites Contagious?

Yes, ear mites can easily spread from one pet to another. If you have multiple pets and one gets ear mites, it is recommended to treat all the pets in the household.


In a nutshell, while Capstar is an excellent solution for flea infestations, it does not have the same effect on ear mites. However, several other effective treatments can help rid your pet of ear mites. Remember, the best defense against ear mites is prevention and regular check-ups with your vet.
