Lavender essential oil contains a chemical called linalool, which can be toxic to fleas and ticks. But, it also poses risks to cats.
In fact, the ASPCA lists lavender plants as toxic to cats.
With all this conflicting information, it’s difficult to know what works and why. So, let’s take a closer look at how safe it is to use lavender essential oil for fleas on cats.

Recently, people have been interested in the possibility of using lavender oil on cats.
In this article we’ll look at this essential oil and its supposed benefits for our pets. Particularly, whether it can get rid of pesky fleas!
What is Lavender Essential Oil?
Lavender oil has been used in medicine and aromatherapy for years, with varying degrees of success.
Its treatment of anxiety in humans has been the focus of numerous studies and trials.
Essential oils are concentrated solutions of the chemicals found in a plant. As such, anything potentially harmful in the original ingredient will be even more potent.
Just because it is safe for humans doesn’t mean that it’s safe to use on our cats.
So, why do so many people want to use it on their cats? And will it hurt your cat if you use it to treat fleas?
Why Do People Use Lavender Essential Oil on Cats?
One recent study showed a lavender oil derived capsule to be very effective in treating generalized anxiety disorder, when taken orally.
When something works for us, we’d like to think it will work for our cats. After all, it’s only natural to think what’s good for us is good for them.
So, some people try to use lavender essential oil on cats to calm them down. But, more commonly, this product is used as a flea treatment.
Some pet flea treatments available to buy contain a diluted lavender oil. And, people often try to create their own concentrate solution at home.
However, this isn’t always safe for our cats.
It’s important to keep in mind no tests have been carried out with cats to determine lavender oils safety or efficacy when diffused. Cats often deal with substances and chemicals in a different way to us.
So, we must find out the pros and cons of this method before trying it on your cat.
Fleas on Cats
Cat fleas are small parasitic insects that most owners struggle with at some point in their cat’s life.
They live deep in your cat’s fur, and survive by drinking your cat’s blood. So, it makes sense that people will try almost anything to get rid of them!
As adults, fleas will measure 1 – 2mm long. So, they can be hard to spot. And, it’s easy for infestations to get out of hand.
If you notice your cat suddenly scratching a lot, you may be dealing with fleas.
There are a lot of flea treatments on the pet market that try to deal with the problem. It ranges from essential oils like lavender oil, to collars and shampoos.
But, just because a product claims to work, doesn’t mean it always does. And, it doesn’t automatically mean it’s safe for your cat.
If in doubt, speak to your vet. But, for now, let’s take a closer look at how effective lavender oil is at getting rid of fleas on cats.
Does Lavender Essential Oil Get Rid of Fleas on Cats?
Lavender essential oil has been shown to kill pests and parasites such as fleas and ticks.
The Happy Cat Handbook - A unique guide to understanding and enjoying your cat!
A study published in the journal of medical entomology showed its ability to kill all life stages of fleas and ticks.
This makes it possible that after coming into contact with lavender oil, cats fleas might be effectively controlled.
However… the chemical that has an effect on these pests can also be toxic to cats, in the right concentration.
So yes, you might get rid of the fleas by using lavender oil. But you could also end up with a very sick cat.
Let’s find out more about the chemical at play, and how it works to get rid of fleas.
How Does Lavender Oil Get Rid of Fleas on Cats?
Lavender essential oil contains a chemical called linalool. Linalool can make up as much as 49.47% of essential lavender oil.
So, the same chemical that makes lavender oil potentially dangerous to your cat could make it a potent flea poison. Linalool is not only toxic to cats, but in the right concentration effectively kills pests.
As we briefly saw in the previous section, linalool solutions have been used in tests to successfully treat cats with fleas.
The cats involved exhibited no adverse effects afterwards.
But, when it comes to home blended or unregulated lavender oil, cats might not be so lucky.
This is because lavender oil is not consistent.
From batch to batch it can differ hugely in composition. So finding the right concentration of linalool in a domestic setting would be almost impossible, not to mention dangerous.
Homemade vs Commercial
It may be tempting to use lavender oil as you might do a normal flea treatment. With the correct placement, normal treatments are usually okay to use.
But, commercial products are carefully controlled.
Your homemade dilution of lavender oil will not be.
There is no real way of knowing just how much linalool is on your cat with lavender oil.
Using lavender oil on cats for fleas domestically is therefore a possibility, but not advisable.
Solutions containing linalool are currently in use as commercial pesticides. But they are treated with caution, and the subject of strict safety protocols.
Linalool, and therefore lavender essential oil, has a demonstrated effect on fleas and ticks. However, it still seems unsafe to use lavender oil for fleas on cats.
Is Lavender Essential Oil Safe for Cats?
To answer the question ‘is lavender oil safe for cats’ we need to define what we mean by safe. Safe when applied topically? Or safe taken orally? Safe to inhale as a mist?
All of these can have different answers.
The ASPCA lists lavender plants as toxic to cats.
Symptoms of lavender poisoning include nausea, vomiting and loss of appetite. These are not things any of us want to inflict on our furry friends.
The reason lavender has this effect is the chemical linalool that we’ve already discussed.
This dangerous concentration of linalool only becomes more of a risk when the lavender is presented in oil form. Around 220 pounds of lavender are used to make one pound of oil.
Natural Does Not Necessarily Mean Safe
It’s easy to think that because a product is natural, it should be safe for your pet. Sadly, this is often untrue.
A great number of plants contain chemicals that could harm your cat. This becomes a serious concern when the chemicals are concentrated into an oil.
Concentrations can vary depending on the lavender itself, or the method of processing. So you can never be sure what you’re exposing your cat to.
If you’re ever in any doubt you should ask your vet if a remedy will be safe.
Is Lavender Essential Oil Toxic to Cats?
The simple answer is yes, lavender oil is toxic to cats.
As we’ve mentioned before, lavender oil contains linalool. This is what makes lavender oil toxic to cats.
From what we know at the moment, it’s probably best not to use lavender essential oil for fleas on cats. Using lavender oil for cat fleas may effectively kill the fleas, but could also harm your cat.
There’s not been a lot of research into cats and lavender oil, when applied to their fur.
We know it can produce skin irritation and allergic reactions in humans and rats. It’s probably best to wait until we know more before you go rubbing it into your cats coat.
It’s also important to remember that cats clean themselves regularly. Anything applied to your pet’s fur may find its way to their mouth in no time at all!
Any lavender essential oil cats accidentally ingest, would expose them to linalool.
How Do You Use Lavender Essential Oil for Fleas on Cats?
Lavender essential oil is seen as a home remedy for cat fleas. However, as we’ve discovered, trying to make and use this product at home can have dire consequences for our pets.
If you’re still keen to find out ways it can be used for fleas on cats, you need to talk to your vet.
They will be able to advise you on the best way to move forward with a flea treatment, and discuss the pros and cons of lavender essential oil with you.
If you’ve turned to lavender oil because you can’t find any other flea treatments that work, your vet may be able to suggest some cat-safe options that you haven’t tried yet.
We don’t recommend using this oil on your cat without talking to your vet first.
Do Other Essential Oils Get Rid of Fleas on Cats?
It’s becoming more and more popular for people to consider using essential oils as treatments for problems their pets have.
But, like lavender oil, not all of these products are without downsides and consequences.
So, do your research before trying any other essential oils on your cat.
The best person to ask for advice and information is your vet. They will be able to show you up to date research, and recommend the best products.
You can also take a look at the ASPCA website to see if any ingredients are listed as toxic to your cat.
Other Methods for Getting Rid of Fleas
If you’re at your wit’s end trying to get rid of fleas, there are plenty of different products you can try that are safer than lavender oil.
To start with, speak to your vet. They may be able to suggest products that you haven’t heard of before, and can let you know any risks associated.
And, while you wait for a vet appointment, head on over to our complete guide about fleas on cats.
This will give you the complete run down of the best treatment methods, what fleas are, and how to prevent fleas from coming back.
Lavender Essential Oil for Fleas on Cats
It’s safe to conclude that lavender essential oils and cats don’t really mix.
Your cat is unable to metabolize the linalool, and this could make them very sick indeed.
A lack of research means it’s safer to err on the side of caution, and steer clear of lavender oil.
Although there is some evidence to suggest lavender oil can have some effects on cat fleas, it’s not worth the risk of attempting to use it in this way at home.

So glad I read this information about lavender…. I contemplated using lavender oil to help my stressed kitty…
Thank goodness I didn’t. Thanks for info
Hi Lesley,
No problem, I’m glad you found it useful!
So would you say that Lavender use through Essential Oil Diffuser is also bad for cats or is the concentration so low that it doesn’t have any impact since it is a drop or 2 of oil for about a cup of water?
Hi John,
Thanks for the comment. You’re right in pointing out that diffused essential oil is fairly weak. If it’s used occasionally it shouldn’t have any negative effects, but I can’t guarantee that it won’t. There isn’t any research to draw on, and the main dangers we hit on in the article are to do with direct exposure or ingestion.
Anecdotes are split on cats loving or hating the smell. If the latter is true it might make your cat a bit reluctant to come into the room where you’re using it.
If you’re using lavender oil for aromatherapy for yourself, I’d say carry on. If you’re expecting it to have a positive effect on your cat you may well be disappointed, as I can’t really find evidence it will have any effect at all. If your cat starts acting strange or avoiding the room you use it in it might be best to stop.
Let me know if you have any more questions,
Tom
What do you think about using lavender essential oils for laundry that your cat may come in contact with? I recently bought some wool dryer balls and the instructions mention adding essential oils to the balls prior to putting in with your laundry. My cat sometimes like to sit in the warm laundry as we’re folding it (though recently he prefers his pet bed warmers — hah!). Do you think this would affect him? Or what about sitting on our bed that has had sheets dried with the balls that have lavender on them? What are your thoughts?
So you’re saying not to use lavender oil in a diffuser? My friend just sent me one and she suggested lavender oil because it helps you sleep and relax of course I won’t have it on at all times just at night but I don’t want to use anything that would hurt my furry children
I’m usually a big proponent of the befits of essential oils. I rarely diffuse them, but was diffusing lavender oil on my nightstand for several nights in a row to help with a cold i had. (I didn’t want to diffuse peppermint or eucalyptus because I knew they were bad for animals). After about 4 nights of diffusing, one of our elderly cats who’d been struggling with chronic diarrhea had a seizure. He’d just had a battery of tests (including an echocardiogram and abdominal ultrasound) that all showed he had no heart or other problems. I’m seriously wondering if it was diffusing the essential oils that caused his seizure. Even our elderly 70 lb dog has been a bit “off” since I was diffusing the lavender oils. Erring on the safe side, I’m not going to be diffusing oils anymore and am going to be very careful about using them on myself around my pets.
I use pure lavender oil as a perfume. Is this a potential danger to my cat?
Hello there. I brought a diffuser to help my sinuses instructed by gp. And advised to use 100% lavender oil. Which I had a number of drops in the diffusers. Unfortunately my car got in my room while the diffusers was misting. Could this m my cat?
I have my defuser going almost all the time with lavender essential oil in it. My 2 cats are fine. I would never do anything to harm my cats. Use your own discretion. Be safe.
I’ve been diffusing lavender and cedsrwood by my bed at night for eight months. I read many blogs that supported it. When she’s sleeping by me I turn it off. She doesn’t leave like she did with wintergreen when I let her smell it. The last two mornings she threw up. No more diffusing for a while. She’s 20, and may be sleeping too hard to leave. Having her liver enzymes tested and Vet is looking into it. It costs abt $50 and may be worth it to some of you. Thanks for all the information. It’s very confusing to know who or what to believe.
wintergreen is one to be very wary of andl wdnt have it near any animals. As it is l
wdnt have even considered Lavender and the older (or younger) the more problem
it is likely to cause
What about food grade lavender oil? I wanted to make some hard candy that will contain food grade lavender oil not essential oil.. but but anytime I make candy it always makes the house smell like what I made the next day or so. Is this harmful to them to inhale?
I use lavender oil diffusers (plug ins) all over my house, and use lavender fabric softener on all my bedding and clothes. I have 19 cats, most are special needs, one is even epileptic, and I have never experienced any difficulty with any of my cats. None of my cats seem to care either way about the smell of the lavender, as they sleep on the blankets that have been treated with it.
I diffuse lavender oil every evening near my bed where both my cats sleep…they become super relaxed & just go to sleep, seems to have a stronger affect on the older cat. Am very careful not to use too much oil & don’t leave it on for more than 20min to 30min/day….Also good to have a window open & the bedroom door open or it will over sedate them
So anybody have more info about dilute lavender (and other essential oils) in human sleep remedy products? I use a couple of essential oil products such as pillow spray and body lotion. Our cat has inflammation up the nose but the reason I don’t think it’s related is 1) it was one sided inflammation suggesting she had a foreign object up there at some point 2) my use of it predates it for years (so not an obvious link) 3) I only use them in the bedroom/at night and she sneezes in all the rooms (though often the bedroom). I want to do what’s right by her but also really struggle with sleep. The article didn’t seem to mention much about inhalation. Thanks
Is it safe to use lavender in my vicks warm mist vaporizer around my cats. I want to put it in bedroom and they all sleep with me
Nice article, nice website/blog, nicely monetize without too much extra garbage on the page. Only thing missing is a link to share it to social media like my Facebook page. At least there is no button for that on my android phone version. But it does format properly. Good job.
