10 Effective Home Remedies for Cat Fleas


by John Staughton (BASc, BFA) last updated — February 27, 2020 ✓ Evidence Based

When your cat has fleas, it can be an annoyance and a danger both for your beloved feline and yourself. Fortunately, there are a number of home remedies for cat fleas, including the use of saltwater, apple cider vinegar, a flea collar, diatomaceous earth, flea comb, additional cleaning, pennyroyal, rosemary, aloe vera juice, lemon spray, garden maintenance and many others.

What is Cat Fleas?

If it seems like your cat can’t stop scratching itself, particularly if the animal has recently been outside, there is a good chance that your cat may be dealing with a case of cat fleas. These small, brown or black insects are scientifically known as Ctenocephalides felis and can enter your home from your cat itself or an outside host. Some of the most common carriers for cat fleas are dogs and cats, but it is also possible that another infected animal may be living in or near your house, populating the space with these quickly reproducing parasites. It is difficult to see these fleas unless you are using a microscope or a dissecting scope, but they are roughly 1/4 inch long. These parasites go through a rather normal life stage cycle, including egg, grub, pupa and adult, but the adults are the only cat fleas that live and feed directly on a host. Female fleas need a healthy supply of blood if they are to reproduce . These infestations of your cat can be very painful for your pet and difficult to eliminate, so you will want to take care of the condition as soon as possible.

Some of the most common symptoms include excessive grooming, intense biting or scratching of their coat, agitation or irritability, obvious avoidance of certain areas of the home, muscle loss, hair loss, lethargy , and red skin lesions or scabbed bumps on the skin. In extreme cases, you might even be able to see the fleas jumping on and off of your cat’s body. This is obviously a hygienic issue for the cat, but if they are removed from the host, they may seek out humans for a meal, which usually results in small raised bumps or lesions on the lower leg. There are a number of intense treatments recommended by certain veterinarians, but there are also many home remedies that can clear up this condition. Let’s take a closer look at these now.

Home Remedies for Cat Fleas

Home Remedies for Cat Fleas are as follows:


The irritated skin of your cat after a nasty flea infection can be red and painful, making for a lot of whining and sleepless nights from your little feline friend. Rosemary has a number of anti- inflammatory properties and is safe for cats in case they take a nibble. It can also stimulate the growth of hairs in areas where it might have been lost due to fleas. You can take a bunch of dried rosemary leaves, crush them into a powder and then sprinkle them on the areas where you cat spends time – either sleeping, napping or playing. This can be a passive way to stimulate healing.

Aloe Vera Juice

Another popular remedy for cat fleas is aloe vera , due to its astringent , anti- parasitic and antiseptic nature. It can smother the fleas and suffocate them, and make the environment unlivable. This won’t have any negative effects on your cats, but it can quickly eliminate fleas. Mix aloe vera juice with some cayenne pepper for an even more effective solution.

Flea Comb

Your cat might not be crazy about being held and combed through on a regular basis, but if you have an outdoor cat, using a flea comb is a must. With this fine-toothed comb, you can successfully spot infected areas and treat them quickly, before they can reproduce and cause a real problem.

Diatomaceous Earth

This specialized mineral can be very effective at eliminating cat fleas because, while it is harmless to animals and humans, the sharp edges can pierce insect exoskeletons and cause them to dehydrate and die. You can simply powder your hands with this and rub it on your cat’s fur, and also sprinkle some on the carpet and bedding to eliminate a possible infestation.

Salt Water

Fortunately, one of the most effective solutions for cat fleas is also one of the simplest. You can mix salt in with water and spray it in areas that you suspect are infected with fleas, and can even clean your floors with it to ensure that there are no eggs developing there. Salt is a powerful repellent for many different types of insects, and even sprinkling salt into your carpets and your cat’s bed can be a great remedy for this problem.

Flea Collar

A more tech-based solution is to simply buy a flea collar. These are widely available at every pet store and are known to be very effective. The flea collar is not actually a “collar”, but rather something that you can cut up and place strategically near your pet’s bed to prevent any infestations. The collar contains insect growth regulator, which makes it impossible for eggs and larvae to develop naturally.

Apple Cider Vinegar

Whether for human problems or feline issues, apple cider vinegar remains one of the most powerful boosts to the immune system. Applying apple cider vinegar to the affected places on your cat’s body can quickly eliminate any infections caused by ticks or fleas, and also promote healing of those irritated areas. White vinegar is another very good solution, particularly for cleaning surfaces in the home.

Additional Cleaning

Regular vacuuming and mopping the floor may seem like more work than you can handle, but if you have a cat, this is an excellent way to prevent any flea infestations. Cat fleas can live in carpet and wait for the perfect moment to infect your cat, but if you regularly scrub the floors and keep the carpets clean, there is nowhere for them to lay their eggs and mature into adults.

Garden Maintenance

If you cat happens to be an outside adventurer, there is a good chance that he/she will catch fleas at some point. If your cat primarily wanders in your garden, however, there is a way to keep her safe from fleas in that specific area. A number of herbs have a taste and smell that is very unpleasant to fleas, ticks and other parasites, so if you carefully place these herbs in key places in your garden or backyard, you can likely avoid this itchy issue. Some of the best herbs for this are tansy, eucalyptus, lavender or fennel.

Lemon Spray

One of the most powerful scents/smells when it comes to chasing away insects, fleas and ticks is lemon, so be generous with your use of it around your home. A simple spray bottle with concentrated lemon juice can serve as a quick protective shield on your cat’s coat, but should also be used around the house in areas where your cats sleeps and plays, to prevent those areas from becoming flea-infested.

A Final Word of Warning

When an infection becomes severe enough, it is essential that you bring your cat to a veterinarian for more intensive treatment. Furthermore, the symptoms of cat fleas can also be indicative of other infections or more serious problems, so it is wise to go to the vet regardless and make sure those bites weren’t from insects carrying any other sorts of pathogens.

Flea Home Remedies & A Flea Trap That Really Work! (Updated!)

Whilst fleas are a major concern for most pet owners, some people may consider fleas to be nothing more than a minor ailment for your pet; however if left unchecked fleas can wreak havoc on pets and humans alike.

Fleas are problematic as they survive on blood. In fact, a female flea can consume up to 15 times per body weight in blood every day. Fleas are not only a nuisance, but they can also cause serious health complications, such as tapeworms, anemia and flea allergy dermatitis, known as FAD. Although they are wingless, these pests can easily jump from pet-to-pet or from pet-to-human, and from room to room around your home.

If you’re looking for ways to get rid of fleas without having to use synthetic chemical treatments, then read on, as the flea home remedies and the homemade flea trap below will soon have your pets and household flea free.

Get Rid Of Fleas With These Home Remedies

The following home remedies for fleas were chosen for their effectiveness and safety. The majority of flea infestations can be controlled and eliminated via these natural methods. To be honest, you don’t really need to look any further than remedy #1 (DE powder) and remedy #2 (flea trap), but the other home remedies are included here, as they are popular and reported to be effective.

NEW POST: Get rid of fleas from your yard/garden with this garlic flea spray for your yard.

Remedy #1 |Get Rid of Fleas with Diatomaceous Earth Powder

Diatomaceous Earth (DE) is actually comprised of ancient algae fossils. Upon contact, the microscopic fossils actually penetrate through the fleas outer shell, and are then soaked into their bodies. Due to the dehydrating effect of DE, fleas are dried out and ultimately destroyed. This remedy is so powerful, DE is often the primary ingredient in all-natural pest cleaners.

Important note: only purchase and use ‘food grade’ diatomaceous earth powder. Other forms of DE, for example, pool DE, can have added harmful chemicals. ‘Food grade’ DE should be clearly labeled as such ‘food grade’.

To utilize this remedy, thoroughly vacuum every room in your home. After cleaned, sprinkle an even layer of DE throughout every room of your home. Focus on areas where humans and pets congregate as this is typically where fleas rest. After the DE powder has rested for 48 hours, vacuum clean. Repeat as many times as necessary to eliminate an entire flea colony. DE really is one of the most effective natural home remedies for fleas, but an added bonus around the home is it also kills ants, spider and cockroaches too!

If anyone in your household suffers with chronic allergies, or skin conditions, it is might best to treat/test one room first (before doing the whole house!), and check for any reactions. DE is considered safe for household use, but you can never be too careful if anyone in your household suffers with a chronic condition.

Using Diatomaceous Earth Powder Directly On Pets?

Food grade diatomaceous earth powder has been used on livestock, all over the world, for decades. It is widely considered safe to use on pets as well. The main caution with using DE on pets is that inhalation of DE should be avoided by humans and pets, as it can cause respiratory irritation, so be mindful of this when using DE powder.

If you are worried about skin irritation, and want to be doubly careful with your pet, try treating a small area of your dog/cat with DE powder for a few days, to see if there is any skin reaction. If all is well, you can proceed to applying the DE powder head-to-foot, being careful around the head area, so that the DE is inhaled. You may need to repeat every few days for heavy flea infestation.

Personally, given DE’s effectiveness at killing fleas, I really cannot see the point in purchasing harmful pesticides and spraying them all over your home. Diatomaceous earth is a safer, natural alternative, that is equally lethal to fleas.

Remedy #2| Homemade Flea Trap

Perhaps one of the most effective home remedies for fleas is to catch these pests before they have time to influence their bite on pets and humans. Although there are many commercial flea traps available on the market, they can be quite expensive. This home remedy for fleas calls upon everyday items to effectively catch and trap fleas throughout your home.

How to make a homemade flea trap

  • Place a baking tray or plate filled with warm water in the middle of the room.
  • Add 1 teaspoon of dishwashing liquid to the water and agitate to make the water soapy.
  • Place 1 tea candle in a jar, in the center of the baking tray/plate and leave overnight. Throughout the night, fleas are attracted to the heat and light coming from the candle. When they jump toward it, they become stuck in the dishwashing liquid water and die. Repeat for three to four consecutive nights, or until you do not wake up to flea bodies in the water.

Homemade flea trap caution – don’t allow pets to access the area the flea trap is located in. They may drink the soapy water, or burn themselves on the candle. If you don’t want to use a candle, you can also try standing an adjustable lamp on the floor, with the light shining into the center of the baking trap/plate. Pets should still be excluded from the area due to the danger of the proximity of the lamp to the water in the flea trap.

Below is a photo of one of our DIY flea traps. To be honest, this old baking tray has much higher sides that our other two traps. I’d have assumed that lower sides would be better, as it’s easier for the fleas to see the light, but this trap works just fine Quick and simple to make, and mighty effective!

Remedy #3 | Homemade Herbal Flea Spray

If you wish to kill fleas throughout your home while leaving a pleasant scent in its wake, then yous should use this herbal flea spray. Each of the ingredients is known to hold powerful anti-flea properties, capable of destroying fleas along the same lines as a chemical treatment without the harmful compounds. To utilize this remedy for fleas, combine the following ingredients into a large container:

  • 1 gallon of white vinegar
  • 1/2 gallon of purified water
  • 16 ounces of freshly squeezed lemon juice
  • 8 ounces of witch hazel essential oil

Once you’ve combined all of these ingredients, pour the solution into a standard handheld spray bottle. After vacuuming the room, spray a liberal amount of this solution throughout your room. Pay attention to corners where carpeting and walls meet. Repeat every day until the fleas have been eliminated. Enhance the effectiveness of this spray by steam cleaning your carpeting and cloth-covered furniture. The steam actively works to kill flea larvae, which can be protected against the spray.

Remedy #4 | Salt Powder – Old Flea Home Remedy

Many ‘all-natural anti-flea powders’ utilize sodium as a means of eliminating these annoying pests. In the most fundamental sense, salt works to kill off fleas by penetrating its shells and dehydrating the fleas from the inside-out. This is an effective, chemical-free, home remedy for fleas that is surprisingly easy and effective. To utilize this remedy, simply purchase finely ground sea salt. In order to work, the salt must be ground to a fine powder. If your salt crystals are too large, grind until it’s a fine powder. The amount of salt you’ll need depends on the size of your room. Once the salt is finely ground, sprinkle throughout every room in your home. Make sure there is an even layer on the carpet. Allow the salt to rest for 48 hours before vacuuming. Repeat until your flea infestation has been eradicated.

Remedy #5 | Homemade Herbal Flea Powder

As you can see, the most effective home remedies for fleas call upon dry powders to penetrate flea shells for full eradication. If you wish to use the power of a flea powder, but without the use of irritating compounds, then you’ll want to utilize this herbal flea powder recipe. Begin by placing all the following ingredients into a coffee grinder:

  • 1/2 cup of dried rosemary
  • 1/2 cup of dried rue
  • 1/2 cup of dried wormwood
  • 1/2 cup of dried fennel
  • 1/2 cup of dried peppermint leaves

Once all these ingredients are in the coffee grinder, grind them together until a fine powder forms. Remove from the coffee grinder and place in a resealable container. Sprinkle the powder throughout your home. Focus on areas where fleas are often found, but also sprinkle in less-active areas. This is an excellent powder to sprinkle around openings of your home, which makes it act as a flea repellent.

Allow the herbal flea powder to rest for 48 hours before vacuuming and repeating. Consider using this home remedy for fleas as an everyday preventative treatment; especially during the warmer months when fleas are most active.

Editor’s Notes

July 09, 2019:

We can’t explain to cats that we’re doing something they find annoying — like putting medication on them — for their own good. So, since ensuring their compliance isn’t possible, we made sure to round up flea treatments that can be given and administered in a number of ways, depending on just what style of finicky your cat is. Should you worry about Fluffy licking her spot-on treatment away, the Bayer Seresto Collar is a great option. Plus, it’s effective for eight months, making it especially helpful for busy pet owners who can’t remember to give treatment daily or monthly.

That being said, we did provide some great spot-on treatments like Elanco Animal Health Cheristin and Vectra for Cats. These break the entire life cycle of the flea, from egg to larvae to pupae, making them great long-term preventative options. Should your poor feline be in the middle of an infestation right now, in addition to investing in a quality vacuum to suck up the intruders daily, try an oral medication like PetArmor FastCaps, Novartis Capstar, or Sentry Capguard. These are your best bet since these kill adult fleas the instant they bite your pet.

Natural Flea Treatments for Dogs: 15 Easy Itch-Relieving Remedies

June 20, 2018 By Sherry Chen

Did you know that most commercial flea medications and topical “spot-on” flea treatments contain toxic insecticides that are harmful to pets?

Flea collars can contain chemicals like propoxur and tetrachlorvinphos which have been shown to hinder brain development. Eek!

Well, it’s time to get rid of those poisonous and expensive flea medications. We found the 15 best natural flea treatments for dogs that are free of toxins and safe for your pup.

Now you can take your pup to the dog park, beach, or backyard and enjoy the outdoors without the fear of fleas and ticks. Try these all natural flea remedies for dogs and say goodbye to those itchy flea bites!

Apple Cider Vinegar

Apple cider vinegar is an age-old natural flea treatment and is one of the best ways to get rid of fleas on dogs. Due to its strong acidity and pungent odor, fleas hate the smell, making it a natural flea repellent.

Therefore, it should only be used as a preventative measure since it won’t actually kill fleas. However, vinegar is highly effective at chasing these pests away and deterring them from coming back.

When using vinegar for fleas, be sure to use raw apple cider vinegar due to its numerous health benefits for dogs. A major benefit is that only raw apple cider vinegar is alkaline-forming in the body. Alkaline foods help to balance out the blood’s pH levels which tend to become acidic due to unbalanced diets. Raw apple cider vinegar can also help moisturize dry skin and promote a shiny coat.

How to Use Vinegar for Fleas

  • Add to your dog’s water or food – You can either add a teaspoon of apple cider vinegar per quart of water or add it directly to their food.
  • Add to your dog’s bath – Lather and massage the vinegar into your dog’s skin and let sit for 10 minutes. Then thoroughly rinse.
  • Make your own natural flea spray – A flea spray is great to have handy for your pet’s bedding, furniture and carpet.

Jenni, proud dog mom from Sweet Pennies from Heaven, recommends mixing 50/50 Bragg’s apple cider vinegar with water. You can also spray this mixture directly onto your dog’s coat, especially before taking them outside.

Diatomaceous Earth for Fleas

Diatomaceous earth is one of the safest natural remedies for fleas on dogs. Consisting of the fossilized remains of aquatic diatoms, each particle is microscopic and shard-like. It kills fleas and other pests like ants and bed bugs by lacerating their exoskeletons. The resulting cuts cause their bodies to dehydrate from the inside out and eventually them.

Since diatomaceous earth is so microscopic it is completely safe for humans and pets. It’s easily considered one of the easiest and most effective natural flea treatments for dogs.

How to use Diatomaceous Earth for Fleas

The best way to use diatomaceous earth to get rid of fleas is to sprinkle it everywhere your pet goes including their bedding, carpet, and furniture. Leave it for a day or two, depending on the severity of your flea problem in the house, and vacuum away the dust. You can even sprinkle diatomaceous earth directly on your dog’s fur and near the base of their tail where fleas tend to reside.

When using diatomaceous earth for fleas, make sure to only use food-grade products.

Essential Oils for Fleas

If you’re looking for a powerful natural flea treatment for dogs, look no further than essential oils. Although it’s one of the most popular flea remedies for dogs, pet owners need to be careful in choosing the right essential oils. There are many types of essential oils that are known to be toxic to pets, such as tea tree oil.

Essential oils in their pure form can also be too concentrated for pets. That’s why it’s important to always dilute essential oils with carrier oils before applying them on your pet.

How to Dilute Essential Oils for Dogs

We recommend diluting one drop of essential oil in approximately 30 drops of carrier oil. Popular carrier oils like coconut oil or sweet almond oil are great to work with and are fairly inexpensive.

Each type of essential oil is different, so you’ll want to adjust according to your pet’s sensitivity towards a particular type. If you have questions about essential oils for pets, be sure to talk to your vet.

Here are the three most effective essential oils for fleas on dogs:


Lavender is one of the best essential oil flea repellents around. Fleas hate the smell of it, and a very small amount is enough to keep them off your dog. An added benefit to using lavender essential oil for fleas is its calming properties, making it a great choice for dogs who have anxiety.

Apply the diluted lavender oil mixture onto your dog’s back. Start from the shoulders, down the spine to the base of the tail. You can create your own DIY flea spray by combining the diluted lavender oil with water. Spray this mixture onto your dog’s bedding, couch and on directly on your pooch before taking them outside.


Cedar oil is a highly effective essential oil flea repellent because it is also a natural flea killer. In addition to fleas, it kills other nasty pests like lice and mites which can cause severe skin irritation.

Other great benefits of cedar oil include:

  • Antifungal
  • Antibacterial
  • Promote hair growth
  • Moisturization
  • Reduce itching
  • Heal hotspots

Ready to kill those fleas? Just remember to dilute the cedar essential oil with a carrier oil before applying it onto your pet.


Lemongrass essential oil contains limonene which helps repel and even kill fleas and other small insects.

If you have cats, you’ll want to keep lemongrass away from them since it’s toxic. Lemongrass can also potentially be toxic to dogs too if you use too much. Therefore, make sure to start with a very low dosage if you’re trying lemongrass essential oil for the first time for flea control or consult your vet.

An easy way to use lemongrass for flea prevention is with a natural spray like Wondercide’s Flea and Tick Spray. It’s a pre-diluted formula that uses lemongrass as the primary ingredient.

Neem Oil

A natural pesticide, neem oil is derived from the seeds of the neem tree. This tree grows prevalently in India and has been known for centuries for its healing powers. It is an all natural and non-toxic pesticide for fleas, mosquitos and ticks. Similar to cedar oil, neem oil not only repels fleas, it’s also a natural flea killer that eliminates them on contact.

Neem oil is not an essential oil, and can be used directly without dilution.

Neem oi is an ideal natural flea treatment for dogs since it also helps with promoting a healthy coat and is effective at reducing skin problems like dryness, itchiness and excessive shedding. Because neem oil is non-toxic, it does not need to be diluted as with essential oils. You can apply neem oil directly to your pet’s skin. It’s one of the best home remedies to get rid of fleas on your dog.

How to use Neem Oil for Fleas

There are a few ways to use neem oil as a natural flea repellent for dogs.

Dogster recommends dabbing a few spots of neem oil on your dog’s head, behind their ears, and on their shoulders and tails.

DIY Flea Spray with Lemons

Just like lemongrass, lemons contain high amounts of limonene that fleas hate. For an easy DIY natural flea treatment for dogs, follow the instructions below to make your own lemon spray!

How to Make a DIY Flea Spray

Thinly slice one whole lemon and boil a pot of water. Add the lemon slices to the pot and turn off the heat. Let steep overnight.

The next day, you’ll have a highly concentrated lemon water that you can use to spray onto your pet. You can also dip a flea comb, brush or sponge and run it through their fur.

For more powerful flea-fighting action, fortify your lemon flea spray by adding a sprig of rosemary, salt and/or apple cider vinegar.

Ultrasonic Flea Tags

Ultrasonic flea tags eliminate fleas by periodically emitting a high-frequency sound that repels many annoying pests including mosquitos and ticks. The sound frequency used is considered safe for dogs, cats and humans and is a completely chemical-free method of getting rid of fleas.

It’s perfect for keeping fleas off your pet in the outdoors like lawns, parks and hikes. Simply clip it onto your dog’s collar let it work it’s magic!

Not only are these great for dogs, they’re great for a variety of other uses as well. Hang one on a baby stroller the next time you go out for a walk; it will keep disease-ridden mosquitos away from your newborn. If you love the outdoors, clip one of these solar-powered ultrasonic tags onto your backpack or keychain for your next camping or hiking trip.


One of the first areas you should look for fleas is in your very own backyard. Lawns can be prevalent with fleas and they can easily latch onto your dog’s fur every time they go outside. Using nematodes is a powerful way to kill fleas in your yard and is one of the most effective natural flea treatments for dogs.

Nematodes are tiny microscopic worms that attack and kill pest larvae including fleas, ticks, and gnats. When released into your yard, they crawl into the soil where they can instantly locate and kill the majority of the flea larvae in the area within 24 hours.

If you’re wondering how to get rid of fleas in the yard, nematodes are relatively inexpensive and easy to use. Specialized spray bottles make it easy to spray the nematodes over your lawn, garden or anywhere else in your yard. Although they are considered parasites to pests, nematodes are safe to use and do not harm plants, humans or animals.

Rosemary Flea Dip

A flea dip is a great natural flea treatment for dogs, since submerging your dog in water will drown out most of the fleas on their body. Since many store-bought flea dips contain harsh chemicals, using a natural flea dip is definitely the way to go.

Rosemary is a natural flea repellent for dogs and is perfect for making your own natural flea dip.

How to Make a Rosemary Flea Dip

Simply boil two pints of water with two cups of fresh rosemary leaves for 30 minutes. Allow mixture to cool.

Add mixture to a bathtub or bucket of water and allow your dog to soak in the mixture. After the soak, allow their fur to air dry. You can also use this rosemary mixture as an after-wash by pouring it over your dog after shampooing.

Natural Flea Collar

Many commercially-made flea collars contain high amounts of toxic insecticides that can be harmful to pets. These chemicals can even cause brain damage in dogs. Yikes! To avoid using toxic flea collars, try making one of your own using natural ingredients.

How to Make A Natural Flea Collar

Dab a few drops of diluted lavender or cedar oil onto a bandana or folded handkerchief. Wrap this loosely around your dog’s neck, especially before going outside. You can also soak the handkerchief in the rosemary dip recipe described above.

For a more potent flea collar that’s all natural, try Arava Flea and Ticks Botanical Collar. This collar contains a powerful herbal cocktail of 11 essential oils including cedar, peppermint, cinnamon, lemongrass, and rosemary to help you fight off those fleas for as long as five months.

Flea Comb

A good ol’ flea comb is an inexpensive way to get rid of fleas on your dog. Running a flea comb through your dog’s fur should be done on a regular basis during flea season. Depending on the severity of the infestation, you’ll want to use a flea comb either once a day or once a week.

Using a flea comb alone will not be very effective in eliminating the flea population on your dog. However, using it along with these other natural flea treatments for dogs will help you get rid of fleas more effectively. For example, you can dip a flea comb into our lemon spray recipe or rosemary flea dip recipe before combing your dog’s fur.

Flea Trap

A flea trap consists of a sticky surface with a built-in bright light. Since fleas are attracted to light, they’ll jump towards the glow only to fall into the sticky trap below it. Flea traps are an easy way to get rid of fleas quickly and are all natural without the use of any chemicals or unwanted odors.

Our favorite flea trap is the Victor Ultimate Flea Trap for its reasonable price and ability to lure fleas in from as far as 30 feet away due to the brightness of its light.


Peppermint is a flea-fighting herb that’s also a soothing agent for itchy, flea-bitten skin. One of the best ways to use peppermint to fight fleas is by using peppermint castile soap as a natural flea shampoo for dogs.

Castile soap is safe for dogs because it is made from plant-based ingredients, is pH-balanced and won’t strip your dog’s coat from its natural oils.

For extra flea-fighting capabilities, the folks at Dr. Bronner’s created a recipe to help you make your own homemade organic anti-flea shampoo.

Dr. Bronner’s Organic Homemade Flea Shampoo Recipe

½ c distilled water
⅓ c Dr. Bronner’s Peppermint Soap
10 drops rosemary essential oil
1 tsp organic olive oil

Directions: Simply mix the above ingredients together and wash the fleas away!

Another great peppermint flea-fighting treatment is Vet’s Best Flea and Tick Pet & Home Spray. Made with natural essential oils and plant-based ingredients, it repels fleas and can even kill fleas on contact. It’s great for spraying directly onto your dog’s coat and everywhere else where fleas might be hiding including bedding, the couch and carpet.

Coconut Oil

Coconut oil contains lauric acid, which is a natural flea repellant. Rub a teaspoon sized amount between your palms and run your fingers through your dog’s coat and skin. It will not only repel fleas but will also moisturize your dog’s skin and promote a healthy and shiny coat as well. Since coconut oil is non-toxic, you won’t have to worry about your pet licking it off and swallowing it.

When using coconut oil for fleas, be sure to only use organic unrefined coconut oil that is free of any additives and preservatives. Unrefined coconut oil also contains the most amount of nutrients, which are usually stripped away in coconut oil that is refined. Coconut oil is one of our favorite natural flea treatments for dogs because it’s so easy to use!

If your pet is itchy from flea and tick bites, try King Kanine’s King Kalm Balm. It’s a CBD-infused coconut oil balm that formulated with Manuka Honey that will reduce inflammation, moisturize the skin and alleviate itching fast.

Brewer’s Yeast with Garlic

Brewer’s yeast is rich in a wide range of vitamin B compounds as well as key nutrients like potassium, selenium, iron, zinc and magnesium. Due to its rich nutrients, brewer’s yeast can help promote a healthy coat and nails for both dogs and cats.

While the jury is still out on whether or not brewer’s yeast alone has flea-fighting powers, supplements containing garlic have been found to be effective. The combination of brewer’s yeast with garlic makes your pooch’s blood unpalatable to fleas and keeps them away.
