My Secret: How To Make The Best Essential Oil Mix For Fleas and Ticks (DIY!)

I've shown you the products, but when it comes to my pets, I really want to make a "potion" that's safe, natural, and made just for my pet! Here's what I usually do:

My Go-To DIY Mix: Essential Oil Based Flea Deterrent Spray

lemongrass essential oil for ticks and fleas


citronella 3-pack essential oil for ticks and fleas


eucalyptus essential oil for ticks and fleas


peppermint essential oil for ticks and fleas


To make the best essential oil mix for fleas, you can add six to seven drops each of peppermint, eucalyptus, citronella, and lemongrass to about 8 ounces of water. If you want, you can also add 3-4 drops of apple cider vinegar. You can click the images above to check out the products.

Stir or shake well then transfer to a spray bottle. When applying to your pet's coat, try to spray it 6-8 inches away from them and be careful not to get anything on their eyes.

I would warn you though that the scent might be overwhelming for your cats. I only tested this for dogs.

For cats, you can try oils with light smells such as lavender, but be careful still.

You can create your own flea deterrent spray by combining water, vinegar, and a couple of drops of the recommended essential oil of your choice. You can place it in a spray bottle and spray it on your pet’s coat, pet’s beddings, and be sure to avoid putting the flea deterrent spray on your pet’s eyes.

That's it for my best essential oils for fleas mix!

Essential Oil-Enhanced Sh​​​​ampoo

Essential oils can actually be mixed to your pet's shampoo for additional antiseptic or anti-parasite properties. The recommended essential oil to be used for your essential oil enhanced shampoo is citronella and lemongrass.

The ideal dosage is 1 drop for smaller pets and a larger dosage for large pets.    

Essential Oil-Infused Brush

Another method that can be used to remove the fleas on your pet is by using an essential oil infused grooming brush (for brushes, I like this and this).

 I like this method because it doesn't disturb the natural oil balance of your pet’s skin. 

This method involves a brush and placing a thick material like a single layer of towel or a folded sheet.

essential oil infused brush

I found this brush to be very easy to use.

You can push the material down the teeth of the steel brush with an inch above the base.

Moreover, you will need to place a bowl of warm water and combine a couple of drops of cedar wood or pine oil and soak the prepared brush in this mixture before brushing your pet’s coat. You should rinse the brush thoroughly during the brushing period in a bowl of essential oil infused water.

The essential oil infused brush treatment will disinfect the dog, condition the coat, and collect the parasites and eggs in the brush.

Other Preventive Measures To Avoid Fleas, Mites, and Ticks

Best Essential Oils For Fleas
  • Add garlic to your pet's diet - Fleas do not like the taste of garlic and if the fleas can taste garlic in the blood of your pets, the fleas would avoid feeding on the blood of your pets. You can dissolve and place a garlic capsule on the food for your pets. You can add in a diluted garlic essential oil to the water of your pet. However, it is best to limit the garlic intake of smaller pets.
  • Give your pet an apple cider vinegar anti-flea drink - Fleas avoid the taste of apple cider vinegar and the fleas will avoid feeding on the blood of your pets if they can taste cider in the blood of your pets. You can add in 1 teaspoon of apple cider vinegar for every 1 quart of water for your pet.
  • Clean your home regularly - The best preventive measure and treatment for fleas is to clean your home. It is important to regularly vacuum and wash the bedding and linens used by your pets. Since fleas fly off your pets, it is important to clean the areas where your pets would usually stay. Another important point to remember is that when you are cleaning, be sure to remove the trash immediately to prevent the flea eggs from hatching and re-infesting your pets. 

Understanding Fleas

Fleas are disgusting. 

And if I hurt any flea-lover out there, I didn’t mean to hurt your feelings.

However, I don’t think there’s someone who loves pet parasites with six legs that feed on the blood of their hosts.

What Can Fleas Do?

They jump easily and they have a compressed physiology that makes it easy for them to run through the hair of your innocent pet. Or in my case, my sweet little Labrador. Basically, fleas are built for your pets body!

Fleas have this weird mindset that the hotter and damper, the better. If you’re living in a place where you can get a decent tan without intending to, there’s a high risk of your pet being infested with fleas.

By the way, the line that says, “Tell me who your friends are, and I’ll tell you who you are,” kind of applies to your dog in this situation. I’m referring to its furry dog pals that he often goes to the park with.

Fleas Make Babies On Your Pet!

Because fleas have this flea-law that tells them - “Oh, look. Another dog. Let’s make more babies on his back.” 

Good news is that they don’t live very long, they’re weak. On the other hand, female fleas are able to make up to 2,000 eggs – in just 4 months!

That’s. Way. Too. Many. Eggs.

I’d be happy if they were chicken eggs, I’d have unlimited protein for a lifetime.

Apparently, adult fleas only mate after they’ve got a good serving of a large blood meal – they basically mate after dining on your dog! Which is why you need to find the best essential oils for fleas and ticks.

Where Do Fleas Hide?

  • Fleas are great in playing the game of hide-and-seek. So when a female flea lays her eggs, these eggs usually fall from their host and incubate to wherever they land...
  • That means…it could possibly land on your bed. Your new roommate will then hatch into a larvae after 10 short days – that is if you haven’t cleaned up your bedsheets, better do that more often.
  • They’re pretty strong for a larvae, they can survive up to 200 days in the environment. But they have their favorite spots to stay. They’re quite choosy, really. You’d find them on your shag carpeting, floor cracks, furniture and bedding.
  • frown-o
    After they had their time of being a larvae, they’ll enter to this new evolution stage, and now they’re called a pupae. They’re not as impressive during this phase, as they’re in a cocoon, all cuddled up. This may be last from days to months.
  • frown-o
    In this stage, they don’t eat – eating disorders? Puberty? I don’t know. It’s just how the phase goes. And finally, when temperature and humidity are right, they make their grand entrance as immature adults – HOORAY! Just kidding.
  • frown-o
    They still have to pass the final test to become a fully-pledged flea. And this is a tricky one for them – finding a host. Oh, by the way. They have a time limit, too. Which is about two weeks.
  • frown-o
    If they don’t find one, they simply rot away and die. They have failed their college entrance exam. For the honorary fleas who have now become mature adults, which is only 1% of them, they’re now free to suck the blood of their host for as long as they want – basically 4 months – and they die.

Overall, they live the go big or go home life, which is why they don’t live long. It doesn’t change the fact though that they can make our pets go bald – pets shouldn’t have to suffer!

Wrapping Up: Best Essential Oils for Fleas, Mites, and Ticks

We love our pets as much as we love ourselves. They make our days brighter, heartbreaks easier, and pockets lighter – because they’re pretty expensive to maintain. But it’s all worth it!

Any of these best essential oils for fleas will help you to prevent those vampire-wannabes out from your pet’s fur. I’m a dog owner, and I can honestly say, I feel like my dog’s invincible!
