Peppermint Oil for Fleas and Ticks

There are a lot of options out there for flea and tick prevention. We covered quite a few of them in our article Best Flea and Tick Prevention for Puppies. If you haven’t had the chance to take a look, I suggest you head over there now. Maybe you are looking for something a little more natural. You aren’t interested in putting chemicals like Fipronil and Permethrin on your furry friend.  Maybe you should try Peppermint oil for fleas and ticks.

There are, however, a few things you should consider before using peppermint oil for fleas and ticks. Natural isn’t always better. Wait. What? If it’s natural, it has to be better than putting chemicals on or into our bodies and the bodies of our pets, right?

Peppermint is natural. It occurs in nature. So does poison ivy, poison sumac, and rattlesnake venom. You wouldn’t want to rub poison ivy essential oil all over your body just because it’s natural, would you?

The word “Natural” isn’t regulated by the food and drug administration the way “Organic” and FDA approved are. Products can be put on shelves with the word natural in 2-inch block letters and it may have never been tested at all. Scary, right?

Are there any Products Already Mixed that contain Peppermint Oil for Flea Control?

Does Peppermint Oil Work Against Fleas and Ticks?

Peppermint Oil for Dogs and CatsHere’s the million dollar question. Peppermint as a plant has been used as an insect repellent for thousands of years.  How effective is it? Meh

The fact that new chemicals have come along that have replaced peppermint as a deterrent to fleas and ticks suggest that it might not be as effective as some people still believe.

Here’s one thing that we do know about peppermint when it comes to fleas and ticks. Peppermint does not kill fleas or ticks. Nope. Not even close.

To be honest, there haven’t really even been any definitive studies on whether or not peppermint repels fleas and ticks. I mean, there must be some reason that humans have used it for that purpose for so many years, but there is just no clear documentation.

Part of the issue is the products that are being tested contain other chemicals as well. How much or the repel is caused by peppermint and how much is being caused by the other chemicals. Remember, “Natural” is not regulated. That means results can be a bit sketchy at times.

How should I use Peppermint Oil for fleas and ticks to get the best results?
