Skye Blake here, with great info on the many “natural” products out there for getting rid of fleas.

Some questions you may be asking…

How do I know which is the best “natural” commercial remedy to use for fleas?

Are they safe to use on my cat or in my house? What’s in them?

Safety Depends On…

Curious cat
  • whether or not you follow instructions carefully
  • what’s in the flea product you use (ingredients)
  • the application method (swallowed or on skin)
  • how much you use (quantity)
  • how often the product is applied (frequency)
  • if they are made only for cats, NOT DOGS! (Your cat’s body processes things differently than a human or dog’s)
  • if they are a proper dosage for your cat’s weight range
  • Asking your veterinarian what products are good for your particular kitty and how to use them

What Ingredients Are In Natural Flea Products?

Reference to safety of natural flea product ingredients

Just as with “chemical” products, you can use commercially available “natural” remedies to get rid of fleas.

They most commonly come in the form of collars, shampoos, or sprays on your kitty.

There are also “natural” powders, sprays, and carpet shampoos for your home.

“Natural” collars, sprays, powders, shampoos, and wipes all have one or more oil, such as peppermint, geranium (eugenol), clove, neem or cedar, as active ingredients.

They are forms of topical flea remedies since they are put on your kitty’s skin, not taken internally (swallowed).

Remember, your clever kitty will lick off anything she can reach while grooming both herself and any other cats or dogs around her.

So whatever you put on her skin (and any other pets) must be safe if swallowed.


In order to figure out what’s best for your situation, review the questions at “Getting Rid of Fleas…For Cats Only!”, if you haven’t already.

You’ll find them quite helpful. If you’ve done this already, keep reading for examples of products on the market.

Best way to keep you and your cat safe is…


Commercially prepared “natural” flea remedy products are already very diluted and have been tested by their manufacturers.

They should work fine for your healthy feline friend. Be sure to get the correct one for your cat’s weight.

Always ask your veterinarian what products are good for your particular kitty and how to use them.

Examples of Natural Flea Remedies

various chemical & natural flea treatments

Below are examples I’ve found of various available natural flea remedies (collars, shampoos, sprays).

Be sure to note whether they kill or repel fleas.

Some kill only adults, others eggs, larvae, and pupae. Others don’t kill but help keep them off your little buddy.

Besides those below, there are other brands of various quality available.

Use them as part of your overall plan to rid your home and fabulous feline of those pesky fleas.

This list is for your convenience only. I make no money from it.

You’ll find them at, or other websites and stores.

Above all, remember, safety in using natural flea remedies, especially when putting directly on cats, depends on…

  • what you use (ingredients)
  • how much (quantity)
  • size of the dose (dosage)
  • how often you use it (frequency)
  • how you administer it (swallowed or on skin)

 If in doubt, check with your veterinarian.

As with “chemical” products, never use “natural” flea remedies

made for dogs on your kitty!

Costs for these products range from cheap ($) to expensive ($$$$): cheap = $ 0-10; average = $$ 10-20; high = $$$ 20-30; expensive = $$$$ 30+

If your kitty wears a “natural” flea collar around her neck it will have a combination of essential oils in it (e.g., peppermint, clove, eucalyptus) to kill and/or repel fleas.

As with “chemical” collars that contain insecticides, some cats with sensitive skin can have reactions where they lose fur and/or get sores on their skin under the collar.

Here are some examples of “natural” flea collars, along with an interesting special collar tag:

  • Only Natural Pet® EasyDefense™ Flea, Tick & Mosquito Dog & Cat Collar Tag – “Causes no harm to your pet—once the tag is hooked onto your pet’s collar, encrypted frequencies will synchronize with your pet’s unique biological frequency, deterring fleas, ticks, mosquitoes and other biting insects without bothering your pet.1ONLY NATURAL PET EASY DEFENSE FLEA & TICK TAG FOR DOGS & CATS – SINGLE TAG $$$

  • Tropiclean® Natural Flea & Tick Collar – claims to repel (not kill) fleas and ticks for up to 4 months; for cats over 4 months old; has a break-away feature $
  • Sentry® PurrScriptions Dual Action Flea & Tick Collar – claims to be fast acting; kills adult fleas; has a growth inhibitor to destroy eggs; for use in healthy cats over 6 months old (not for pregnant cats) $


flea spray bottle

“Natural” flea sprays have oils as their active ingredients (e.g., peppermint, rosemary, cinnamon, eugenol).

They’re used to help get rid of fleas and ticks, while some also kill or repel mosquitoes.

Sprays aren’t as popular now for using directly on us fabulous felines, but are still available if you want them.

Flea sprays are more often used on bedding, furniture, floors and other things in your kitty’s world.

This is because most kill only adult fleas, get your cat all wet, and other products are available that are easier to deal with for cats.

You may decide, though, that it’s a worthwhile part of your overall plan for using natural flea remedies.

Here are some examples of “natural” flea sprays…

  • Vet’s Best® Cat Flea & Tick Gentle-Mist Spray – claims to kill fleas and ticks on contact; also works on flea eggs; use on cats 12+ weeks old; can also be used on bedding, furniture, blankets, etc. $$

“Natural” flea shampoos, like collars and sprays, have essential oils as their active ingredients, in dosages that will kill fleas while cleaning your kitty safely.

That’s if you can give your cat a bath!

These are useful only if your furry friend will tolerate a bath, but, if not, there are plenty of other options.

It sure isn’t worth having your arms, face and other body parts clawed, bitten and shredded… to say nothing of having a totally freaked out cat!

For you brave souls who want to bathe your buddy, here are some “natural” shampoos to use as part of your flea remedy plan.

  • Only Natural Pet® EasyDefense™ Pet Shampoo – claims it can be used on pets older than 4 months year-round $$
  • Vet’s Best® Waterless Bath Foam – claims it’s good for cats 12+ weeks old, who don’t like baths or sprays; gentle formula; claims it kills fleas, eggs and ticks $$
  • Natural Chemistry Natural Flea Shampoo for Cats – Has cinnamon, clove and cedar oils; claims to work for 7 days $$
  • Wondercide® Geranium Natural Shampoo Bar for Dogs and Cats – Has coconut, geranium and citronella oils; claims the bar is easier to use than liquid shampoos and is gentle enough for sensitive pets $$



There are some flea powders available but are mostly used on dogs and in the house (carpets and floors).

Powders are not recommended for use on cats because…

  • They’re messy (think clouds of baby powder)
  • They’re only effective while on the cat
  • They rub off quickly
  • They’re swallowed during grooming. (Cats will also groom dogs so if you have both it’s best to not bother with powders for either.)
  • It’s claimed that powders in large amounts can cause breathing problems in cats. While this is certainly possible, I have found no hard proof.

Oral Flea Remedies

If you’re interested in using “natural” versions of the flea pills or other systemic medication, you may need to reconsider the “natural” part.

From the info I’ve found, there are currently only a few types available and they are typically “chemicals” of various kinds.

My page, “Is a Flea Treatment with Chemicals Safe for My Cat?” has an interesting section about oral flea remedies.

Don’t discount them simply because you don’t consider them “natural”.

Keep an open mind and read the info first before deciding, then if you still have questions, check with your veterinarian.

To sum it all up, “natural” flea remedies are available ready-made as collars, sprays, and shampoos, using various oils as active ingredients.

They’re not always as effective as “chemical” remedies, but are more convenient than trying to make your own (see “Flea Control the Homemade Way” for DIY “homemade” remedies).

Sources used on this website are either primary or secondary.

Primary are always preferable and have the most reliable information because primary sources are original and directly referenced. Scientific abstracts and data are good examples of primary sources.

Secondary sources are weaker because they usually consist of opinions or articles that give no sources of their own, however, sometimes they refer to primary sources.

Thus, when I use secondary sources most are those with some authority, such as veterinarian or cat behaviorist books and articles.
