Sandra Tashkovska Sandra Tashkovska May 20, 2025

Although we rarely see them, fleas can cause serious discomfort for our dogs, especially during the warmer months. At some point, you may find yourself searching for ways to prevent a flea problem. Or worse, you might already be dealing with an infestation and desperately looking for a solution.

There are many flea treatment options available on the market, from natural essential oils to strong chemical spot-ons, and choosing the right one for your pet can be a challenge. You might even wonder if those natural options are safe and efficient.

We are here to answer all your concerns about essential oils for fleas on dogs. We will find out what the best option is to keep your dog safe and sound!

Why Do We Need to Keep Away Fleas?

Fleas might be tiny, but not harmless! They are attracted to dogs because they provide them with the perfect conditions. Inside the dog’s coat, they find warmth and moisture, and of course, fresh food (blood).

They can attach to different body parts, including:

  • Neck and ears
  • In-between toes
  • Base of the tail
  • Belly and inner thighs

After attaching, they reproduce rapidly and can lay up to 50 eggs per day. And if you ignore all of this, you will only give the fleas and ticks the perfect conditions for attacking your dog.

Fleas and ticks, if found on time, can be treated, and you can avoid the worst-case scenario, serious disease, or even death as a consequence. Once you start suspecting that your dog has fleas or ticks, include some natural remedy, or even better, ask for professional health advice.

Remember that if you keep ignoring this problem, you will also increase the chances of flea infestation in your home!

What Are Essential Oils?

Essential oils are still chemicals, but they are derived from plant materials and can be used as antimicrobials, medications, pesticides, and as home refreshers. These oils are highly concentrated to bring the natural “essence” of a plant.

Essential oils can be made from different parts of the plants and they are known for their strong aromas. Usage of these oils goes back to the ancient Egypt, from which many other medicines and scientific reveals came from.

However, us, modern people, started actively using them in the early 20th century when the interest for natural remedies and holistic health became more popular.

Essential oils are made with extraction with the process of steam distillation. The process is simple, steam passes through the plant material and causes the oil to evaporate. Other common methods include:

  • Cold pressing
  • Solvent extraction
  • CO2 extraction

Besides the holistic approach of using essential oils, there are other ways in which these oils can be used:

  • Aromatherapy
  • Cleaning
  • Topical application
  • Pest repelling
  • Beauty and care

Here are common popular essential oils for repelling fleas: ‘

  • Basil
  • Lavender
  • Lemongrass
  • Rosemary
  • Rose Geranium
  • Cedarwood
  • Clove

Can Essential Oils Kill Fleas?

People look for natural treatment options, and that is the main reason for the popularity of essential oils. It is not necessarily the safest option, however it helps pets a lot.

Chemical treatments are widely used, but they can cause side effects and leave harmful residues in the environment. One study evaluated the in vitro effectiveness of five essential oils, Zanthoxylum limonella, citronella, clove, peppermint, and ginger against ticks and fleas, and examined the skin sensitivity in dogs.

The following results were found:

  • At 16% concentration, all five oils significantly reduced tick egg-laying.
  • At 2% and above, they effectively killed tick larvae.
  • A 4% concentration rapidly eliminated fleas, and clove oil killed 100% of fleas within 1 hour.
  • Clove oil at 16% was the most effective and safest for use on dogs' skin.

So, science says that essential oils can be a safe and effective natural alternative to chemical flea and tick treatments.

The only problem is that not every dog will have the same reaction and efficiency. That is why, before applying any new holistic medicine on your dog, first, do a patch test. This way, you will test how your dog responds to that specific treatment.

What Other Uses Do Essential Oils Have?

No matter your purpose, before applying essential oils, we advise you to consult with your vet. There are many ways in which essential oils can be used, and here are some of them:

  • Reducing stress and anxiety
  • Skin and coat care
  • Odor control

Side Effects of Essential Oils

Not always the natural option is the best option. It is mainly because of the unwanted incidents that might happen during the application. Dogs might accidentally swallow, and gastrointestinal signs like vomiting and diarrhea can arise.

Respiratory distress is another incident that might happen. These oils are very concentrated, and even a minor mistake while diluting the oil can be harmful to your dog. Signs like rapid breathing and coughing can happen during the application.

After the essential oil absorbs and enters the bloodstream, it can also lead to some serious side effects. This includes bleeding, organ failure, fever, seizure, collapse, coma, or even death.
