Flea Home Remedies – Main Care Suggestions

 â­Use a sensitive pet shampoo  to help calm your pet's skin. 

â­Use a good pet vaccum  regularly and empty.  

Bath Time 

Flea Killing Lather Bath

Any pet shampoo that makes a lather, when mixed with water, will kill existing fleas. When bathing your dog, ensure that you leave the lather on for 2 minutes before washing thoroughly.

I suggest, also on top of the normal bathroom cleaning you would do, vacuum all carpets thoroughly, where the dog has been, to minimise reinfestation. It will also keep on top of the fleas that are still in the immediate area.

Wash the dog towel at 60 degrees, to denature any fleas and eggs present.

✅ An organic, sensitive shampoo is definitely the way to go, as your pet's skin will already be irritated by flea bites, so it will need gentle treatment. 

Fresh Rosemary Leaf Bath

Fleas really hate rosemary!

Boil up rosemary leaves in a pan.

Strain and then add to some warm water. You could either use it in the bath, to bathe your dog in (make sure the temperature is comfortable) or you could pour it on them as a fun game!

Lemon Bath

How beautifully fresh will your dog smell after this lemon bath! Lemon juice when mixed with water is a natural deterrent for fleas. They have a full recipe, suitable for cats and dogs, which can be used in a spray bottle. When done, the rest can be added to pet shampoo.

Hunker also suggests adding rosemary, for an added layer of deterrent.

Add a 1/4 cup of lemon mixture to your pet's shampoo.

This is a safe way to keep a lemon scent in your pet's coat when bathing them to make sure fleas don't return. Also, make sure not to get the shampoo near your pet's eyes.

Organic dog soaps as a natural flea repellent 

These soaps are superb. Just apply to your dog as you would normally while bathing. The essential oil components a naturally repelling to fleas.

Look out for anything with:

  • Eucalyptus
  • Lemongrass
  • Lavender

This Neem oil and teatree oil soap is also very effective and with homemade dog soap you know that there won't be any added nasties. 

Lathering up in the bath for your dog can get rid of fleas

Multi-purpose neem oil 

Neem oil is well known for a range of purposes such as:

  • Pesticide
  • Insect repellent
  • Itch reliever – allergies, mange treatment
  • To fight off infections and viruses – it is antibacterial, antiviral and antimicrobial.

Once neem is applied, it enters the bloodstream and prevents reinfestation for some time. Big win!

How should I use Neem oil as a natural remedy for fleas?

Dab it!

Some owners use neem oil on key areas where you find fleas. So in warm places like:

Behind ears.


On the flanks

Around the tail.

This is especially great for cats, who as we know, object and hate being bathed!

Dilute neem oil with grapeseed oil or olive oil. Apply it every two to three days to prevent reinfestation.

Mix it with Shampoo

You need to plan this one out a bit because you can only mix this natural flea treatment just before you bathe your dog. (The mixture tends to separate otherwise and the neem becomes inactive)

Mix one teaspoon of neem oil to two teaspoons of dog shampoo.

Massage well into the skin and leave on for 5 – 10 minutes before rinsing.

Neem Oil Spray

Again this is a natural flea killer that you will need to use the same day as you prepare it. (The neem oil will become inactive after this amount of time).

Mix one part neem oil to ten parts warm water. Add a small amount of essential oil to make it smell better.

Spray all your dog’s coat generously. Just make sure to avoid the eyes, cuts, ears or mouth.

Pro tip – 

  • Avoid letting your pet use the furniture as neem can smell unappealing. 
  • Keep them out of areas you don’t want them to go, until it has soaked into their skin.

Homemade natural flea collars

 Collar with vodka or Cedar oil or lavendar oil flea collar.

You know just by the smell of chemical flea collars, how harsh they are. They can be irritating the sensitive animal skin and irritating to the lungs.

Not only that, chemical flea collars can be dangerous for children in the home.

Here is an article detailing step by step how to make non-toxic flea collars. Please note, essential oils should not be used on animals under 12 months old.

No time to make one? You can actually but pre-made flea collars with natural ingredients now. One of the options is to go one with 100% cinnamon, which is also a natural flea repellent.

Essential Oils Flea Spray 

Make a natural flea repellent by adding six or seven drops of the essential oils of rosemary, peppermint, eucalyptus, tea tree, and citronella to a cup of water and shaking well. 

Use a spray bottle to apply the solution to your dog's coat every other day.

Apple cider vinegar and salt spray

 Fleas absolutely hate apple cider vinegar and salt spray – it makes it impossible for them to live on your dog.

The best thing is that your dog will remain comfortable throughout the process.

Jetpet Recipe

Dilute six cups of apple cider vinegar with four cups of water, add a dash of sea salt, then spray directly onto your dog’s coat. Make sure to avoid your dog’s eyes.

Coconut oil

Coconut oil is a great home remedy for fleas as it works from your dog’s coat.

Fleas become stuck and suffocate, as soon as you apply the oil.

It breaks down their exoskeletons and quickly kills them.

However for humans and animals, coconut oil is so kind that you can even use it on your puppy. It has antiseptic properties also, so will sooth your pet’s coat and those itchy flea bites.

How Do I Use Coconut Oil as a Natural Flea Treatment? 

Coat Your Dog’s Skin 

Take as much coconut oil as you can fit in your hands and warm it. (It is hard in its raw state, so to spread it, you will need to warm it up).

Massage it into your dog’s skin thoroughly, making sure you touch the skin with it. Massage into the key areas where fleas hide. (armpits, head, behind ears, around tail)

To be really thorough, you can at this point, brush their fur.

This will remove more critters!

Leave on for at least 8 hours.

Coconut Oil Spray

This can be used as a repellent.

Warm up equal amounts of coconut oil and water. Melt and combine in the microwave.

When comfortably warm, spray generously over your pet’s coat. Avoid the eyes.

Consideration – if you have any left over, store it in a container that you can reheat in a microwave, as the coconut oil will harden and need softening again.

Combs to treat fleas naturally

Lemon juice comb

Lemon juice is just brilliant as it is ultra repelling for fleas, but harmless to humans and dogs.

Just dip your pet comb or brush into some lemon juice and brush as normal. If you have a short haired dog, you can just use a cloth and wipe it on.

Flea Comb

Team up this fleacomb with other natural methods as a truly natural method of keeping fleas away. Flea combs are specially designed to remove fleas and their stick eggs, so is a highly effective natural method of flea removal.

Other advantages are: 

  • You don't need to use harsh chemicals. 
  • Your pet will be more relaxed and feel like they are having an enjoyable cuddle.
  • You don't need to put them through the trauma of a bath, if they don't enjoy it. 

✅ Manual flea comb    In my opinion this is the best type of manual flea comb. It won't cause knots. 

✅ An electronic flea comb could be an option, especially as this one is silent. It can be used on cats and dogs.

Combing can interrupt and reduce fleas

Cedar Chips

 This is an intriguing idea. Waycooldogs has an expert article about using cedar chips as a home remedy for flea treatment.

Food and drink home remedies to get rid of fleas

Brewer's Yeast 

For dogs, a daily dose of brewer's yeast mixed with a small amount of garlic in their food will help to keep fleas away.

Use about 1/2 teaspoon (1.4 g) of powder for every 10 lb (4.5 kg) your dog weighs.

You can also put brewer's yeast in your cat's food, but don’t give the garlic (onions and garlic are toxic for cats).

This is a great, fun recipe for creating home-made treats with brewer’s yeast and coconut oil.

They are so cute and suitable for dogs and cats too!

✅ Check brewer's yeast prices

Diatomaceous earth

This can be given either externally or internally.

It’s made of crushed fossils of freshwater marine life and organisms. Very close up it looks like mini fragments of glass.

It’s very disruptive to all insects as it pierces their protective armour and essentially dries them out, killing them.

This is a big win for your dog as it can kill fleas, ticks, lice and mites. If you want to control worms and internal parasites, you will need to get the food grade version.

The other non-food grade version can be sprinkled on your dog’s coat, around the yard, and anywhere they sleep.

Internal home treatment – diatomaceous earth Food grade

Give these amounts:

  • Small dogs and puppies: 1/2 tsp per day in food
  • Up to 50 lbs: 1 tsp per day in food
  • Over 50 lbs: 1 tbsp per day in food
  • 100 lbs or more: 2 tbsp per day in food

It’s best to mix it with moist food. If you feed your dog dry food, add some water or broth to make the powder less dry.

External Treatment

To get rid of fleas, rub the powder into your dog’s coat by starting near the tail and pull back the hair to get it on the skin.

Avoid the eyes, nose and mouth as it can irritate sensitive membranes.

Sprinkle diatomaceous earth non-food grade on bedding and carpets too. Let it sit for up to 3 days, then launder or vacuum.

Flea treatment for house – home remedies

Baking Soda

  • Baking soda dehydrates fleas and their eggs.
  •  Sprinkle baking soda directly onto your carpet.
  • Sweep from side to side with a broom, to enable it to penetrate and disturb the fibres.
  • Leave the baking soda on your carpet overnight, then you can simply vacuum up the baking soda and the fleas in the morning.


Salt is also a dehydration agent, helping to get rid of adult fleas.

Finely ground salt works the best. 

  • Sprinkle it all over your carpets in each room.
  • Leave the salt to rest for 1-2 days, then vacuum your home throughout.
  • As with all these treatments, the key is to empty the contents of the vacuum, to dispose of any eggs and live fleas.

Make a flea sachet

Make a flea sachet and put in pet bedding or around where your pet sleeps. 

To use place 2 or more bags around the area, depending on the size of the animal.

You just need a 6, 4″ x 6″ drawstring muslin bags or large seal and brew teabags. 


– 2 cups dried catnip leaves & flowers (or just leaves) 

– 2 cups dried sage leaves 

– 1 cup dried rosemary leaves

 – 1 cup dried thyme leaves 

– 15 drops rosemary essential oil 

(OMIT for cats, dogs under 1 year old and all dogs under 20 lbs)

Rejuvenate with one drop of oil every week.

The herbs will need replacing every 2 months and the bags replaced or washed.

To conclude

There are many home remedies for fleas on dogs and cats. But it is worth a bit of experimentation to explore what fits and works for you and your household. It can only be a good thing, to use more natural flea treatments, for our pets, us and ultimately the environment too!
