Keeping bloodsuckers like fleas and ticks off your pet is a major responsibility for pet parents, as these parasites can carry diseases that can hinder your fur baby’s health. And while flea and tick medications are the most effective preventative strategies you can use, some pet parents are likely tempted to try home remedies and alternative methods for tick and flea removal.
The problem is these flea and tick preventative methods dont work. And on top of that, some can harm your pet or create other health issues.
Here are 11 common home remedies for fleas and ticks that are not only ineffective but detrimental to your pet’s health.
Many people want to bathe their pet as a home remedy for fleas. While a cat or dog flea shampoo may do the trick, using dish soap for flea treatment is not effective enough.
Dog and cat skin has a different pH level than human skin, “and using dishwater detergent can actually be dry and irritating to their skin,” says Dr. Robert Lofton, DVM, assistant clinical professor at the College of Veterinary Medicine at Auburn University in Alabama. “And its not going to control the fleas,” he adds.
Even if the dish soap does help kill adult fleas, bathing your pet in dish detergent does nothing to address the eggs and larvae. Those left behind will grow, breed, and repopulate your pet—and your home.
“People forget that there are four life stages to a flea: the egg, larva, pupa, and adult. You need a medication that controls the entire life cycle,” says Dr. Lofton. “Even if what you use kills the adult fleas, that isnt control.”
For puppies and kittens that are too young for flea medication, dish soap is safe to use to kill adult fleas. But alternative methods need to be used to control the flea population in the environment, or else they will become infested again.
It is excellent at absorbing smells and has been suggested by some online pet sites for use as a flea killer because it “may” dry out flea eggs and larvae. But there is no evidence that using baking soda to kill fleas is effective at all. There are better methods to try than baking soda for fleas.
Some home remedies for fleas suggest that garlic, especially when mixed with brewers yeast, will repel fleas. The theory is that when a dog eats this combination of garlic and brewer’s yeast and sweats, the garlic scent will emit from a dog’s body, making him an unappealing feast for fleas.
“Garlic is not an effective flea or tick repellent on dogs or cats, since they dont sweat like humans,” says Dr. Mike Hutchinson, DVM, a veterinarian at Animal General of Cranberry Township in Pennsylvania.
In addition to not being an effective treatment method, garlic is toxic to cats and dogs if ingested. It’s best to keep garlic away from your pets.
Have you ever watched your furry best friend scratch constantly and felt helpless? I’ve been there and it’s heartbreaking. When my golden retriever Max couldn’t stop itching last summer, I went down a rabbit hole of natural remedies and kept seeing tea tree oil mentioned for flea control. But does tea tree oil actually help with fleas on dogs? The answer might surprise you.
The Quick Answer: Tea Tree Oil and Dog Safety
No, tea tree oil is NOT safe or effective for treating fleas on dogs.
Despite what many wellness blogs might suggest, tea tree oil can be toxic to dogs even in small amounts According to PetMD, as little as seven drops of 100% tea tree oil has caused poisoning in dogs, and amounts as small as 10-20 milliliters have caused death in dogs and cats
Let’s dive deeper into why this popular essential oil is problematic for our canine companions.
Understanding Tea Tree Oil
Tea tree oil (also called melaleuca oil) comes from the Australian tea tree plant (Melaleuca alternifolia). For humans, it’s commonly used for its:
- Antibacterial properties
- Antifungal benefits
- Anti-inflammatory effects
- Anti-itch relief
- Possible antiparasitic effects
You’ll find it in many human products like shampoos, lotions, and even insect repellents. While it can be beneficial for people when used topically (never orally), the same cannot be said for our four-legged friends.
The Dangerous Myth About Tea Tree Oil and Fleas
There’s a persistent myth in natural pet care circles that tea tree oil kills or repels fleas. This simply isn’t true. No scientific evidence supports using tea tree oil on dogs for flea control, and the risks far outweigh any theoretical benefits.
As PetMD clearly states: “Tea tree oil will not effectively kill fleas on your dog. Traditional flea preventions are strictly regulated for their safety, whereas essential oils are not.”
Symptoms of Tea Tree Oil Toxicity in Dogs
If your dog is exposed to tea tree oil, they might develop these concerning symptoms:
- Weakness
- Excessive drooling
- Skin irritation or chemical burns
- Wobbly, unsteady gait (ataxia)
- Inability to walk
- Tremors
- Low body temperature
- Collapse
- Mouth ulcers
- Pneumonia (from inhalation)
- Seizures
- Increased liver enzymes
- In severe cases, death
One study examined 336 dogs exposed to varying amounts of 100% tea tree oil and found that ALL dogs displayed neurological symptoms to some degree. These symptoms typically begin within two hours of exposure and can last up to three days.
What About Diluted Tea Tree Oil Products?
You might wonder: “What about pet products that contain tea tree oil? Are those safe?”
Some veterinary products do contain very small amounts of tea tree oil (less than 1-2% concentration), such as certain shampoos or ear washes. These products are generally considered non-toxic IF:
- They’re used exactly as directed on the label
- You monitor your dog to prevent them from licking the product off their skin
- They’re specifically formulated for veterinary use
However, there are much safer and more effective options for flea control, so why take the risk?
Safe Alternatives to Tea Tree Oil for Flea Control
Instead of reaching for tea tree oil, consider these safer alternatives for keeping fleas away from your dog:
Veterinarian-Approved Flea Treatments
- Oral flea medications prescribed by your vet
- Veterinary-approved topical flea treatments
- Flea and tick preventative collars designed specifically for dogs
Other Essential Oils That Repel Fleas (Safer for Dogs)
According to Wellness.guide, these essential oils are generally safer for dogs when properly diluted and used correctly:
- Cedar oil – Often considered the “champion” among flea-repelling oils
- Lavender oil – Milder option that may help repel fleas
- Lemongrass oil – Has a pleasant citrusy scent that fleas dislike
Important note: Even these “safer” oils should NEVER be applied at full strength to your dog’s skin. Always consult with your veterinarian before using any essential oil product on your pet.
How To Use Essential Oils Safely Around Dogs
If you do decide to use pet-safe essential oils for flea control (not tea tree oil!), follow these guidelines:
- Always dilute properly – Essential oils must be diluted with a carrier oil like coconut oil or almond oil
- Never apply directly to skin – Instead, apply to collars or bedding
- Avoid diffusers – Dogs should never be in rooms with essential oil diffusers
- Watch for reactions – Monitor your dog closely for any adverse reactions
- Consult your vet first – Always get professional approval before trying any new treatment
5 Effective Ways to Use Safe Essential Oils for Flea Control
Based on recommendations from Wellness.guide, here are some safer ways to use appropriate essential oils for flea prevention:
-
Essential Oil Infused Brush – Spray a steel brush with a properly diluted essential oil solution before grooming your pet
-
The Bucket Battle – Fill half a bucket with water (10 liters) and add a few drops of dog-safe essential oils, then mop floors to deter fleas
-
Flea Protection Collar – Apply a few drops of properly diluted cedar oil (not tea tree!) to the outer side of your pet’s collar, let dry completely before putting it back on
-
Safe Spray Solution – Mix 1 cup of vinegar with 3 cups of water and add cedar oil and lavender in very small amounts to create a spray for bedding (not directly on pets)
-
Pet-Safe Shampoo Enhancement – Add 1-2 drops of dog-safe essential oil to your pet’s regular shampoo (again, not tea tree oil)
What To Do If Your Dog Is Exposed To Tea Tree Oil
If your dog has been exposed to tea tree oil, take immediate action:
- Contact your veterinarian or the Pet Poison Helpline (855-764-7661) immediately
- Do not induce vomiting unless instructed by a professional
- If the oil is on their skin, your vet may recommend bathing with a dishwashing liquid like Dawn to remove it
- Get to an emergency vet clinic as quickly as possible
Treatment typically involves supportive care, including IV fluids, medications to control neurological symptoms, and liver support therapy.

My Personal Experience
When Max was suffering from fleas, I almost tried tea tree oil after reading about it online. Thankfully, I consulted our vet first, who warned me about the dangers. Instead, we used a prescription flea treatment that cleared up the problem within days, without any risk to Max’s health.
I’ve learned that when it comes to our pets’ health, natural isn’t always safer. Sometimes the professionally developed solutions really are best.
The Bottom Line on Tea Tree Oil and Fleas
Despite what some wellness blogs and natural remedy enthusiasts might claim, tea tree oil is NOT safe for dogs and is NOT effective against fleas. The risks of toxicity far outweigh any potential benefits.
Your best bet for flea control is to:
- Talk to your veterinarian about proven, safe flea treatments
- Keep your home and yard clean to reduce flea populations
- Regularly wash your dog’s bedding in hot water
- Vacuum frequently, especially in areas where your dog spends time
- Consider safer natural deterrents only as a supplement to veterinary treatments
Remember, your dog depends on you to make safe choices for their health. When in doubt, always consult with a veterinary professional rather than relying on internet advice – even mine!
Have you dealt with fleas on your dog? What safe methods worked for you? I’d love to hear your experiences in the comments below!
Boric Acid (Borax)
Boric acid is commonly found as the main ingredient in some flea powder products you can sprinkle onto your carpets. It’s created by combining borax with acid.
While it can possibly be effective as part of a multipronged flea-management strategy, boric acid alone can only kill the flea larvae living in carpets or rugs that are actively feeding. Flea larvae only make up about 35% of the flea population in an infested home.
Boric acid is not effective against adult fleas or ticks because they only feed on blood and will not ingest the powder. It also won’t work against flea eggs (50% of fleas in the home) or flea pupae (10% of the flea population).
The easy answer to the question “does coconut oil kill fleas?” is a firm no.
Coconut oil has a lot of great uses. The polyunsaturated fatty acids in coconut oil can reduce inflammation and help support cognitive function in pets. However, coconut oil does nothing to repel fleas and ticks.
Oil applied to your pet’s skin will only be effective at getting your floor and furniture greasy. The thin layer of coconut oil on their skin does not provide an effective barrier for these tenacious parasites.
Coconut oil should never be applied to your pet’s skin unless recommended by your veterinarian for small areas of irritation or dryness.
While diatomaceous earth can be used in the environment to kill adult fleas, do not apply it directly to your pet. It’s not effective for flea control when used in this manner, and it could potentially result in lung damage if inhaled. It can also cause gastrointestinal (GI) upset if ingested by dogs or cats.
Tea Tree Oil
Like cedar oil, you should never use tea tree oil as a home remedy for fleas. Pure tea tree oil is incredibly toxic to dogs and cats—even small amounts (10–20 milliliters) have caused death.
It’s best to avoid using any essential oils around dogs and cats. Even inhaling certain oils (such as from a room diffuser) can cause serious issues in pets.
Using salt to kill fleas is dangerous and ineffective. The amount of salt required to kill flea eggs and larvae is toxic to your dog or cat if they lick it or get it up their nose.
You would need a truckload of salt poured into every surface and crack in your house to know that all the flea eggs and larvae are dried up. At that point, you might as well move!
