The cat flea or the Ctenocephalides felis is the most common type of flea found on cats and dogs. Occasionally though, rabbit and hedgehog fleas may also be found on felines and they can be equally distressing for pet owners.

This guide will help you answer all those questions. I will be discussing easy recipes of homemade flea spray for carpet that you can use safely around your beloved pet.

We will also discuss a handy list of essential oils that kill fleas on cats without any allergic reactions or toxicity.

So, without further adieu, let us delve right into the heart of the matter.

What are Cat Fleas?

Typical Ctenocephalides felis or the cat flea is reddish brown in color-female fleas measure about 2-2.5 mm in length and are slightly longer than males.

Fleas feed on cat and dog blood but can also take intermediate hosts like tapeworm, possums, rodents etc.

They are known to transmit bacteria in the bitten animal causing a wide range of diseases which could even be fatal. Cat fleas cause anemia in younger and weaker animals and can even lead to tapeworm infestation.

The problem with dealing with a flea infestation is that it tends to spiral out of control within no time. This is because; a single female flea can lay up to 500 eggs in her lifetime!

The larvae also grow into adulthood within no time and soon they are reproducing as well. Fleas also need a whole lot of blood meal to complete their life cycle stages.

So they always need a host around them. In absence of dogs, cats, and other wild or domesticated animals, fleas will not hesitate to bite humans.

How To Control Fleas At Home and on Pets?

Successful control of fleas requires you to take 2 steps:

  • Control and repel them on your cat
  • Also control them in the cat’s environment.

Majority of cats spend a lot of time outdoors and that makes them very susceptible to acquiring fleas. That is why it is very important to use round-the-year flea protection for these pets.

Thankfully, there are many safe and effective essential oils for fleas on cats that repel fleas. I will be discussing them shortly.

Infested cats and kittens come home to rest atop furniture, under beds, in hutches, above the entertainment centers and so on. They have a habit of shaking their bodies which deposits fleas, larvae and eggs in your home. So, all these areas become potential breeding grounds for fleas.

Therefore, you must vacuum each and every room and clean and wash pet bedding in hot water. It is also important that you bathe your pet using vet approved shampoos.

We will soon discuss some natural shampoo recipes to keep your cat flea-free. Later, I will talk about a homemade flea spray which you can spray around the house and on carpets to keep it pest-free. This homemade spray contains essential oils which are safe for use around cats.

Why Use Natural Flea Treatment for Eliminating Cat Fleas?

Natural ways to get rid of fleas on cats are a safer option compared to chemical flea control. Many monthly flea products contain pesticides, organophosphates and a slew of other chemicals some of which have even been banned by the Environmental Protection Agency.

Recently, a report published by the NRDC or the Nation Resource Defense Council recommended a complete ban of such products because it stressed the fact that we were unknowingly killing our pets with these products.

Moreover, chemicals like organophosphates also pose great risk to human users and could lead to birth defects, endocrine changes and even certain cancers. 

So, as a pet owner who wants the best for her/his pet, avoid using chemicals and you will find the entire household much healthier.

Essential Oils: the Best Way to Get Rid of Fleas in the House When you Have a Cat

Therapeutic grade essential oils for fleas are very effective repellents. Ticks and fleas both hate the smell of these oils. Naturally, you need to reapply these essential oils weekly since their aroma dissipates and gets lighter over time.

So, unlike monthly flea control products, you might have to use the homemade flea spray for cats every few days.

However, I strongly believe that the payback of using essential oils is a greater alternative to chemicals. You and your pets will both benefit tremendously from switching to natural ways of flea control.

In the beginning, you will need to use essential oil flea and tick repellent recipe very frequently based on the pet’s health, the degree of infestation and also your pet’s daily routine. For example, if your cat is always outdoors or you have had to board it in a pet daycare facility; chances are that it is bombarded with fleas and ticks there.

So it is important that you take all these factors into account and use the requisite quantity of flea spray recipe discussed in this guide.

Apart from homemade flea spray for cats, I will also be discussing other ways in which you can use essential oils for controlling and repelling fleas. I will talk about a simple flea collar recipe, shampoos and even a flea powder with essential oils.

Before moving on to essential oil recipes for fleas on cats, let us discuss which oils are safe for use on felines.

Best Essential Oils for Flea Control in Cats

Eucalyptus oil

In diluted form, eucalyptus essential oil is generally safe for cats. Never let your cat smell Eucalyptus essential oil directly. If you plan to use this oil topically for flea control, make sure you dilute it well. Use coconut or olive oil for dilution.

You can also add a few drops of Eucalyptus oil to your cat’s shampoo and use the mixture for bathing your pet.

Also add a few drops to the final rinse water when bathing an infested cat. The strong smell of eucalyptus drives fleas away.

Lemongrass oil

lemon grass essential oil

Lemongrass essential oil is generally well tolerated by cats. However, as with any aromatherapy essential oil, make sure you dilute it well with coconut oil or olive oil before topical use.

These days many pet shampoos contain lemongrass oil due to its strong insect repellent properties. You can also add a few drops of lemongrass oil in your cat’s shampoo or make a flea powder by mixing it with arrowroot powder. I will discuss a flea powder recipe shortly.

Cedarwood oil

cedar wood essential oil

This pleasant smelling oil is an effective flea repellent and is quite safe for cats as long as you dilute it well.

It has antibacterial and antifungal properties as a result of which many creams for treating skin issues like eczema in cats contain this oil.

Lavender oil

Lavender oil is one of the safest essential oils for fleas on cats. Its unique fragrance not only repels fleas and ticks, it also calms your pet and soothes skin problems.

Sprinkle dried lavender buds around pet bedding and also add a few drops of pure lavender oil to your cat’s shampoo.

Citronella oil

Citronella Essential Oil

Citronella oil has been used since centuries for repelling all kinds of bugs. Spritz a bit of the diluted oil all around your pets’ bedding. Before using citronella topically, make sure your cat likes it.

You can try a smell test to ensure your cat loves the smell. Always use this oil diluted when using around cats.

Clary sage oil

This oil makes a great dip for dog and cat fleas. Avoid using the oil around pregnant cats.

Diffuse the oil around the cat’s bedding to instantly calm the animal. Also apply diluted to its paws or the neck to repel ticks and fleas.

Essential Oils that are Toxic to Cats

Several essential oils are toxic to cats...

  • Camphor oil
  • Tea tree oil
  • Peppermint oil
  • Almost all Citrus oils (Lemon, Lime, Orange, Bergamot, Tangerine)
  • Clove oil
  • Pennyroyal oil
  • Spruce oil
  • Niaouli oil
  • Carrot seed oil
  • Juniper oil
  • Wintergreen oil
  • Oregano oil

Smell Test of Essential Oils for Cat Fleas

No matter how safe an essential oil might seem to use around cats, you must perform a small ‘smell test’ first. Such a test will show you if your pet likes the smell of the oil. If it does not like the smell, it will run away or hide.

To perform the smell test, dip a Q-tip in the oil bottle. Wipe the Q-tip on a rag or piece of paper. Place the rag/paper near the cat. If your cat is not allergic to the oil’s smell and seems to like the smell, it will play with the paper/rag. If not, s/he will try and run away from it.

Many essential oils can even cause severe toxicity in felines. The symptoms of poisoning include:

  • Vomiting
  • Lethargy
  • Confusion
  • Muscle weakness
  • Excessive sneezing
  • Drooling
  • Partial paralysis

Never ever give essential oils internally to cats. They lack liver enzymes to eliminate them.

This causes the oils to remain in the system for long periods and can lead to permanently elevated levels and varying degrees of impaired liver function.

If you suspect poisoning, seek medical help immediately.

As a pet owner, you too should exercise caution before introducing any new essential oils in the pet’s environment.
