One of the main reasons pet parents use peppermint oil on pets is to repel tick and fleas from their dogs instead of conventional medicine. It is a traditional pest repellant that has been in use for both people and animals for thousands of years.

Fleas and other pests like ticks and mosquitos find the strong peppermint smell unbearable. Therefore, you will hardly ever see any landing on your pet provided the scent is there. Also, when combined with other more potent ingredients, peppermint can kill these nasty pests.

Even on its own, peppermint can kill flea larvae, meaning it will be handy at controlling an infestation. Better still, applying peppermint oil on your dog helps soothe the itchy flea bites, leaving the pup feeling more comfortable.
