What kind of collar can you use?

Making your own flea collar can be an economical and creative option for pet owners looking for a more natural way to keep their furry friends safe from pesky pests. Depending on the fabric type and the essential oils used, flea collars have the potential to be a stylish accessory as well as a safe form of pest prevention.

For the DIYers, various tutorials are available online for making your own essential oil flea collar. You can create a traditional collar by adding a few drops of essential oils to an existing pet collar or make a sophisticated bandana from some scrap fabric and pinking sheers. The best part is you don’t need a lot of skill or expensive materials to get started.

Folded pink, red, and purple bandanas.

I like to use bandanas so our pups can match the seasons and be washed with the regular household laundry as needed. Here are some collar patterns I’ve used and had success with, in case you want to get a bit fancier:

No matter which style collar you choose to use, cotton is the best material to select. It holds essential oils better than synthetic materials like polyester and nylon. Just keep in mind if you are using yarn, cotton yarn lacks the stretch of acrylic, so adjust the length of the finished product accordingly.

The Flea-Repelling Essential Oils

Many oils repel insects, but when it comes to fleas, two have worked the best for me – rose geranium and lavender. By blending these two together, you can create a pleasant scent that is also an effective flea repellent.

Rose Geranium Essential Oil

Ah, the sweet scent of rose geranium. It’s no wonder why this fragrant flower has been an integral part of herbal remedies and even incorporated into cosmetics for centuries. Yet, beyond its known benefits for humans, rose geranium has an added bonus that can prove to be invaluable for pet owners: it can keep the dreaded fleas away.

This is because the tiny pests rely on their powerful sense of smell to detect hosts. If a host smells anything that’s out of the ordinary, the fleas will usually stay away. Rose geranium has a strong scent that throws off its receptors, making the host unrecognizable.

Studies have shown that applying a few drops of rose geranium may reduce flea populations by up to 85%. You can purchase Rose Geranium Oil here.

Lavender Essential Oil

Lavender is an all-purpose oil frequently used on our homestead, and it also fits the bill when it comes to our flea collars. Research done by the University of Ohio showed that lavender essential oil not only repels fleas, but it interrupts their hatching cycle. Further research has indicated that lavender repels as effectively as DEET when used at a 10-20% dilution.

You can purchase Lavender Essential Oil here, and I recommend buying it in bulk because you’ll find hundreds of uses for it.

How to Make Your Essential Oil DIY Flea Collar

Are you ready to see how easy this is? In one hand, hold your collar. In the other, apply 3-5 drops of each oil. That’s it! You can put all the drops in one spot or space them out around the collar. I prefer the latter. 

Refresh the collar with your essential oil blend whenever the smell dissipates. I usually switch out my dogs’ natural flea collars weekly during the summer because they get grubby playing outside with the kids. I rotate between two for each dog, so on Sundays, I take the old bandana off, toss it in the wash and put the second one (fresh with oils) on them.

A Note on Cats

This DIY flea collar is not suitable for cats. Cats have highly sensitive skin and senses of smell. For a DIY cat flea collar, check out this tutorial from Is That Your Cat. She uses lavender oil as well as cedarwood, thyme, and citronella. She also utilizes alcohol and carrier oil to prevent sensitivities.

Does it work on ticks as well?

Yes, it does! Both of the essential oils in this collar work wonders as tick repellents as well. Regardless of your flea and tick remedy, furry friends should always be checked regularly for ticks. The fact of the matter is that no flea and tick product is 100% effective. This is especially true if you’ve been journeying into the woods.

Frequently Asked Questions

The frequency of refreshing the oils depends on factors like your dog’s activity level and the effectiveness of the essential oils. Generally, refreshing every 1-2 weeks is a good practice.

Gradually introduce the collar, allowing your dog to get accustomed to it. Start with short periods and use positive reinforcement to associate the collar with positive experiences.

Washing the collar may dilute the essential oils, so it’s recommended to use mild detergent and air dry. Consider refreshing the oils after washing to maintain effectiveness.

Store the collar in a sealed bag or container to preserve the scent of the essential oils. This helps maintain its efficacy between uses.

Monitor your dog for signs of irritation, excessive scratching, or any unusual behavior. If you observe any adverse reactions, remove the collar and consult your vet.

  1. 5 stars
    Hello, Does this repel mosquitos too? I have heard Heartworms are caused by affected mosquitos. Thank you

    1. Jessica Knowles says:

      It does as far as I can tell. My dogs don’t seem nearly as bothered by them as they use to be.

  2. It’s important to only use essential oils that are safe for pets. Some lavender plants of the 200 plus species are safe and some are not. This applies to all essential oils.

    I only use animaleo oils that were created for pets. I do not sell these oils so I do not benefit from recommending them.

  3. 🙁 the oil you gave a link to was not rose geranium…

    1. Jessica Lane says:

      I’m sorry Sucorra. The link has been updated.

  4. Jennifer M says:

    Good morning! I love your idea, so just dbl checking, 3 to 5 drops of both geranium and lavender? Planning on using this when i board my dogs for a week soon. I also give them premeasured garlic tablets, im thinking i will like to give them a little,extra protection when theyre around other dogs and not home:) thnx so much!!

    1. Garlic, onions and anything else from the allium family is very toxic to dogs. It causes hemolytic anemia which can lead to an early death of the animal.

      1. Gerry Jaworski says:

        No it’s not. Real garlic is safe, your minced or powder deadly. Real is not.

  5. Ellen Briggs says:

    Thank-you for this! My dog and I both are allergic to flea collars. My face broke out from holding my dog and hugging him, and it causes my dog a terrible itching that seems to be worse than the fleas themselves. I will definitely try this one!!!

    1. Jessica Lane says:

      Let me know how it goes!

  6. I mix up a solution of pennyroyal oil, bergamot mint, water and rubbing alcohol in a fine mist sprayer (like a re-purposed travel size hairspray bottle). Shake well before you apply to your hands and then your dog. I rub the legs, back/tail and belly. Take care not to put on face. Dogs have very sensitive noses and they don’t like the aromatic oils very much. Pennyroyal (mint family) is an excellent tick repellent.
    Works for people too! Spray pants and boots when trudging through the weeds.

    1. Pennyroyal is poisonous for dogs and cats. Be very careful!!!

  7. Angi @ SchneiderPeeps says:

    Thanks for the idea. I’m going to have to try this on my naughty dogs.

  8. What a great idea! I wonder if a cat would stand for it?

    1. Jessica Lane says:

      A similar collar would work for cats. Although there is no research on the effects of rose geranium oil on cats, I myself would switch that oil out with rosemary. It may not be quite as effective, but in partnership with lavender, it should do the trick. Two other things to note, cats should have break away collars to prevent choking. Also, you’ll want to apply less oil to the collar because cats tend to be more sensitive.

  9. Ricki @ The Questionable Homesteader says:

    Now I’m going to have to get some rose geranium essential oils. Thanks 😉
    Although I’m thinking I might have to do the bandanna thing with mine. She has collars that would work, but really the bandanna is styling, and it might help her look less scary…
    Thanks for sharing.
