What Essential Oils Kills Fleas?

Thousands of dog owners are constantly searching for a way to get rid of pesky fleas, and many people turn to essential oils as a natural solution. While some oils work better than others, it’s important to choose the right oil for your dog and use it safely.

Some of the most effective essential oils include lemon oil, eucalyptus oil, lavender oil, and peppermint oil. Simply add a few drops of any of these oils to your dog’s shampoo before lathering them up during their bath. When using any of these oils on your dog, it is important to do a patch test first to make sure they will not have an adverse reaction.

In this blog post, we’ll discuss a few essential oils that are known to kill fleas, as well as share some tips on how to use them. Keep reading to learn more!

12. Lavender

Lavender takes the top spot with its combination of benefits that promote prevention and recovery from flea and tick infestation. It is highly effective in repelling bugs, especially when combined with other pungent essential oils like peppermint.

Lavender also has a calming effect on the dog which definitely makes dealing with the uncomfortable conditions easier for everyone involved.

Finally, lavender has been shown to be effective against mange for getting rid of the mites and soothing the irritated skin. For these and other benefits, we strongly recommend Cliganic USDA Organic Lavender Essential Oil.

11. Peppermint

Peppermint is one of the most popular essential oils in commercial flea eradication preparations. However, it only serves the purpose of repelling the ticks and fleas and does not actually kill them. There is also the fact that it has the potential for being irritating in concentrated amounts. It is, therefore, best used together with other oils like lavender for the dog’s safety and for overall increased effectiveness.

For this, we recommend you try Cliganic USDA Organic Peppermint Essential Oil for both topical and diffuser use.

10. Rose Geranium Oil

This is not a very commonly used essential oil but it is very effective for getting rid of fleas and ticks. It stands out in that in addition to repelling the bugs with its strong fragrance, the oil can kill them in different stages of life. For this effect, it is best to apply a diluted amount to the dog’s skin by spraying or massaging. Just make sure they don’t taste it because it is bitter.

Try Healing Solutions Rose Geranium Essential Oil which is perfect for its pure rose geranium oil formula.

9. Lemongrass

Lemongrass smells fantastic unless, of course, you are a tick or a flea. They tend to avoid spaces where the scent is strongest. This means you can use it not only on your dog but also on furniture and carpeting where the fleas like to hide and breed. Check out Gya Labs Lemongrass Essential Oil. Its formula allows for different uses including spraying, direct application, or aromatherapy which makes it one of the most versatile and convenient solutions on our list.

8. Eucalyptus

Eucalyptus is easily one of the most effective essential oils when it comes to killing ticks, mites, and fleas. It kills the adults, larvae, and even the eggs for complete eradication.

However, it is important to note that when ingested, eucalyptus could cause problems for the dog including diarrhea and pain. It is, therefore, best applied in diluted forms. For this, try the Nature’s Truth Eucalyptus 100% Pure Essential Oil which is particularly awesome for aromatherapy and surface sprays.

7. Thyme

Thyme is highly effective in repelling fleas and ticks with its spicy natural fragrances. However, it does not actually kill the fleas or their eggs so several applications may be required to completely get rid of the creepy crawlers.

For the dog’s safety, it is best to apply it either as a diluted spray or through aromatherapy. We recommend Healing Solutions Organic Thyme Essential Oil, which is organic and free from any chemical additives.

6. Rosemary

Rosemary is very gentle on the dog’s skin and is therefore fantastic for repelling fleas and ticks through baths.

Just prepare your pooch’s bathwater and add a few drops of the essential oil into the water. Let the dog soak in it for a few minutes then go on with your washing. This coats their fur with the beautifully scented oils, thus repelling the bugs.

For this, try the Botanical Beauty Organic ROSEMARY Essential Oil which has the purest and highest quality formula out there.

5. Neem

Neem extracts have for a very long time been used as pesticides and insecticides. They are very effective in killing fleas at different stages of life. The oil also offers soothing effects on skin irritated by the bites while also helping to prevent infections and inflammation.

Natura Bona Organic Neem Oil is one of the best options for you on the market. It is fantastic for sprays and topical applications, in general, to deal with the infestation.

4. Chamomile

Chamomile does a lot for the dog when it comes to flea and tick infestations. First off, it has a sweet scent that the bugs absolutely hate. It is therefore perfect for getting rid of them whether it is on the dog itself or on surfaces where they like to hide.

The oil also has anti-inflammatory effects and also calms the often agitated dogs down. Aura Cacia Pure Roman Chamomile Essential Oil definitely stands out with its pure and light formula that is perfect for aromatherapy.

3. Cedarwood

Cedarwood is one of the most potent options on this list of essential oils for killing fleas and ticks. It is one of the few that in addition to repelling the crawlers also kills them. It is also safe enough to apply to the dog’s skin. However, it should be diluted either with water or carrier oils for this purpose.

Options like Healing Solutions Cedarwood Essential Oil are also fantastic for use in essential oil diffusers to get rid of the pests everywhere in the house.

1. Clove

Clove is extremely pungent and, therefore, super-effective when it comes to dealing with fleas and ticks. It repels them not only from your dog’s body but also from indoor spaces. When applying it to the dog, it is best to dilute it because if it is in concentrated amounts, it could have some toxic effects.

We recommend the Healing Solutions Clove Essential Oil for its pure and therapeutic grade formula that is ideal for both aromatherapy and dog sprays.

Are Essential Oils Safe For Dogs? 

Essential oils are completely organic and are, therefore, mostly safe for dogs. However, there are some exceptions that have toxic effects, especially when consumed by dogs. These include cinnamon, citrus, pennyroyal, peppermint, pine, sweet birch, and tea tree. They should also not be applied to the skin to minimize the risk of transfer to the mouth.
