Our Overall #1 Rated Pick

(updated as of 1/13/2019)

Bayer Seresto Cat Flea Collar

  • Auto release collar to prevent choking
  • No vials, no drops, and no wet messy cat
  • Collar lasts 8 months for continued protection

Bayer's flea collar is one of the main reasons flea collars are making a comeback. 

The broad insecticides imidacloprid and flumethrin kill current fleas within 24 hours and kill any new fleas who try to jump on within 2 hours.

We like it because it is simple - no vials, no drops, and no wet messy blobs of fur on my cat. It lasts 8 months and has a auto release to prevent choking.

A little expensive but definitely worth it for your cat.

Also as a public service announcement.

There are SO many knockoff "natural" essential oil based collars popping up. Most of them are run by non-experts looking to sell cheap collars that have little or no effect on your cat's fleas. If you look closely at the reviews of these products they are mostly fake and/or for completely different products!

Below is a screenshot from poor people who bought a terrible knockoff cat flea collar that did not work. Check it out!

Even more frightening is that some cats are EXTREMELY sensitive to essential oils as they lack the proper enzymes in their liver to breakdown when the chemicals as they're absorbed into their skin.

Don't buy those unless you're on a REALLY tight budget and you have no other option.

Seresto is a reputable brand that we can stand behind that DOES NOT use essential oils. The rest of the companies we keep seeing popup are constantly getting negative reviews and bad feedback from their customers.

AVOID them, please and go with Bayer's Seresto Collar.

We all know how difficult it can be to give a cat a bath...

We endure multiple escape attempts, flying water bombs, and the wrath of claws and teeth.

Bad stuff.

Bathing your cat regularly is one of the most recommended tips to get rid of fleas.

Unfortunately, it isn’t always practical or possible for me and my water-hating cat. A few cat owners are lucky to have cats who love water, and to them we say, “No fair!” for we have had to turn to other, more aggressive flea control methods.

Enter cat flea collars.

Flea collars were once the top choice to when dealing with cats with fleas, until the development of more powerful topical “spot-on” drop treatments.

Some owners continue to use collars due to their lower cost, or for cats who have allergies or reactions to topical spot-on products. New formulations of flea collars are proving to be just as effective as other treatments and their popularity is growing.

That being said... let's get into how to go about buying these collars.

If you want to know about how to get rid of fleas overall, check out our other guide here.

Dangers of fleas on cats?

No one likes to see their cat suffering with fleas. The constant biting and scratching is unnerving for anyone.

Not only are fleas an annoyance, your cat is at risk for serious health issues when these pests take control.

Fleas are ectoparasites, which means they bite and feed off the blood of their host. If you don’t take the necessary action, your cat can get diseases and parasites such as anemia, tapeworms, cat flu, and flea allergy dermatitis.

​We recommend checking for fleas on your cat on a regular basis so you can stop major outbreaks before they take hold. Cats are excellent groomers and may be able to hide the problem well. You should use a flea comb on your cat’s fur, check for dead fleas in bath water, and pay attention to behavior changes such as excessive licking or biting.

Adult fleas leave behind small specs of dark-colored digested blood. Brush your cat over a white towel or large piece of paper to look for this “flea dirt.” Still unsure? If you add water to the specs, you will notice they turn red.

It is important that you act quickly once you notice a flea problem on your cat. Flea collars may be a good, relatively low maintenance option for you to treat fleas on your cat, depending on the severity of your flea problem.

How do collars work for cats with fleas?

Designs

The designs of collars vary depending on the formulation of the insecticide used. There are two primary types – solid and liquid.

  • Solid: For the solid type, solid insecticide and resin are mixed so that as the collar wears away from rubbing against your cat’s skin and fur, the insecticide releases over time. Depending on the specific insecticide used, it either disperses across your cat’s skin or absorbs into the top layers. For the dispersion type, the flea only needs to contact the insecticide for it to take effect. For the absorption type, the flea needs to bite the skin.
  • Liquid: The liquid insecticide preparation releases as a gas. These are most effective for repelling fleas, but not killing them.

Insecticides on Flea Collars

Some ingredients, called adulticides, only kill adult fleas. Two examples are imidacloprid and fipronil. Insect Growth Regulators (IGRs) are hormones that render adult fleas, eggs, and larvae sterile so they can’t reproduce.

Two examples of IGRs are pyriproxyfen and S-methoprene. They successfully end the life cycle of the fleas and help to control them over time.

How effective are flea collars for cats?

Some products combine adulticides with an IGR to reap the benefits of both – quick relief for your cat from bites and a way to avoid the spread of new fleas. A few flea collars can kill adults within 24 hours and last up to 8 months making them comparable to liquid drop treatments without the mess.

One thing that can reduce a collar’s efficacy is getting it wet multiple times per week. Most collars are listed as “waterproof” so a monthly bath should be ok, but too many and the insecticide could wear off. If your cat plays in water, you may want to take the collar off, put it in a plastic bag, and replace it once your cat is dry again.

The effectiveness of a flea collar is limited to your cat – not the eggs, larvae, and pupae in your carpet or in cracks of your wooden floor. IGRs can help some, but it will take a while for those take effect.

The fleas you see on your cat only account for a small amount of the overall infestation. An adult female flea lays about 50 eggs each day and most of these fall to the ground. Adult fleas represent just 5% of your overall flea population. Another 50% are eggs, 35% are larvae, and 10% are pupae. To eliminate your flea problem completely, you need to focus on treating your home environment as well.​

How to get rid of cat fleas in you house?

No matter which type of flea collar you choose to use for your cat, it is critical that you use Integrated Pest Management (IPM) tactics to eliminate fleas. IPM promotes the use of a variety of approaches to kill or sterilize the fleas and eggs on your cat, in your home, in your yard, and on items such as pet bedding and linens.

Using IPM requires a thorough understanding of the cat flea life cycle so you know which products to use in different areas. Pay close attention to the labels of products to determine if they work on killing adults, eggs, larvae, and pupae. Products that say “Repels fleas” will most likely not be effective in removing fleas you already have.​

Be careful to not combine too many products on your cat or in areas where they live as too many chemicals can be toxic. Check with your veterinarian to determine the best approach for your situation.​

Vacuuming is one of the most advised techniques you can use to stop the spread of fleas. When larvae hatch, they eat eggs and flea dirt.

Vacuuming at least once per day may help to reduce their food source so they won’t survive. You should also vacuum before you do any home treatments such as spraying or using a fogger.

Vibrations and heat can cause pupae to hatch, which would leave them more vulnerable to the effects of the chemicals.

Be sure to empty out the canister or bag away from your home so the fleas don’t jump out. Some people even put cut up pieces of flea collars in their canisters to kill the fleas they catch.

Are Flea collars safe for cats and humans?

Flea collars are generally considered safe for cats and humans, but you should take some precautions. Most flea collar labels clearly state “Do Not Allow Children to Play with Collar.” Some insecticides are more toxic to humans than others. If you handle a collar, you should wash your hands.

You don’t need to be concerned with petting your cat while they are wearing a collar, just wash your hands after. Even if you were to ingest some of the insecticide, it would take a much larger amount to do any harm. To be on the safe side, just use some common sense.

As with any product, even those considered safe, some cats will experience a negative reaction. If your cat has hair loss, sores, or redness around the neck, discontinue use and consult your veterinarian.

There may be some discomfort in the first few hours as the fleas go through the dying process. Unfortunately, the fleas can still bite for a short time while the chemicals take effect.

Another concern with collars is the possibility of strangulation. Make sure you select a collar with a safety release mechanism that opens once the pressure goes over the limit.​

Cat Collars For Fleas Products Reviewed

Using flea collars can be a good strategy for getting rid of fleas on cats. Here are a few of the top choices available on the market right now.

  • Very easy to use and put on
  • Comparable to "spot on" treatments
  • Brand name collar

This product is one of the main reasons flea collars are making a comeback.

The broad insecticides imidacloprid and flumethrin kill current fleas within 24 hours and kill any new fleas who try to jump on within 2 hours.

We like it because it is simple - no vials, no drops, and no wet messy blobs of fur on your cat.

Other collars tend to lean on essential oils, which can be toxic to some cats in the wrong doses.

Pros

  • check
    Very easy to use- just size the collar, put it on, and you're good to go
  • check
    Slow release of chemicals allows the collar to last up to 8 months
  • check
    Quick release safety latch to prevent choking
  • check
    Not oily or greasy
  • check
    Comparable to "spot on" treatments

Cons

  • Not an all-natural option
  • Some may find this collar to be expensive
  • Kills fleas, ticks, and more
  • Breakaway collar fits all cat sizes
  • Works for 7 months

If you can't afford the Seresto collar, then the next best brand we like is the Adam's style. Their formulation is a bit different but still works in the same way to kill fleas and their larvae.

It's worth pointing out the primary active ingredient in this collar is Tetrachlorvinphos (TCVP), which is actually more toxic to pets and animals (especially fish) than imidacloprid, the active ingredient from the Seresto brand. There's an ongoing effort by the Natural Resources Defense Council (NRDC) to get the EPA to ban this pesticide and protect the environment.

The bottom line here is Adam's makes a cheaper cat flea collar with slightly more toxic ingredients. It's up to you if the cheaper cost is worth the increased risk to your pet's health.

Pros

  • check
    More affordable than the Seresto brand collars
  • check
    Provides up to 7 months of protection
  • check
    Breakaway collar fits all neck sizes for your cat

Cons

  • Uses TCVP a more toxic active ingredient
  • All cat flea collars pose a risk and reaction in cats
  • Kills fleas and ticks
  • Has a growth hormone to disrupt the flea life cycle (S-Methoprene)
  • Water resistant

Similar to the Adam's flea collar mentioned above, the Hartz Ultra Guard collars uses the same active ingredients. Specifically, 14.55% Tetrachlorvinphos to kill fleas and 1.02% S-Methoprene to kill flea eggs and larvae, which is the exact same as Adam's.

That said, our recommendation is the same. If you can't possibly afford the Seresto collar than this is a viable alternative, although more toxic and risky toward your cat.

Pros

  • check
    Another affordable alternative to the Seresto collar
  • check
    Last up to 7 months
  • check
    Water resistant
  • check
    Breakaway collar fits all cat neck sizes

Cons

  • Uses TCVP a more toxic active ingredient
  • All cat flea collars pose a risk and reaction in cats
  • Contains all natural ingredients
  • Good for ticks as well as fleas
  • A bit more affordable

This all-natural option is good if you want to avoid chemicals. I would choose this collar if I or my cat had skin sensitivities or if I wanted a non-toxic alternative.

You will definitely need other products to get rid of a flea infestation, but it is a good option for prevention.

Pros

  • check
    Kills and repels fleas AND ticks
  • check
    All-natural ingredients such as geraniol, citronella oil, cinnamon oil
  • check
    Last up to 3 months
  • check
    Water resistant

Cons

  • Natural ingredients can still irritate your cat's skin
  • Some cats may be bothered by the smell
  • Shouldn't be used to combat a whole flea infestation
  • Has a safety release to prevent cat choking
  • Has a nice scent
  • 6 month duration

This collar is similar to the Hartz collar with the same insecticide at a slightly larger amount. The cost is higher though and it doesn’t come with a safety release.

This collar will work, but between the two, we would probably choose the Hartz.

Pros

  • check
    Kills adult and baby flea eggs
  • check
    Money back guarantee 
  • check
    Fragrant scent 
  • check
    Water resistant
  • check
    Lasts 6 months

Cons

  • Made in China
  • Does not have safety release
  • Strong chemical insecticide 

Our Top Pick: Bayer Seresto Cat Collar

While there are several products available that are effective in killing fleas on cats, Bayer Seresto's collar is our top pick for a flea collar and may be my top pick of any topical product.

The choice between spot-on treatment or the Bayer Seresto collar comes down to personal preference, and is not so much based on which one is more effective anymore.

Bayer may be the better option for cats who don’t tolerate drops well, or who spend too much time trying to lick the solution. The Bayer collar has brought flea collars back into the mix as a strong option for quick flea elimination and long-term flea control.

Alternatively, we also recommend checking out our trusted exterminator search tool. You enter in your location details and get a couple free quotes to knock our your problem quickly. 

Fleas aren't something to mess around with.

If you feel the least bit uncomfortable handling pesticides and/or other chemicals around your pets, our recommendation is to use the tool, find a couple exterminators (they're all pre-qualified) and ask them your questions.

  1. Alternative to Seresto . I need 5 cat flea collars that contain 10% flumethrin and 4,5 % midaceoprid. Seresto is too much money for me as I am on soc sec.

    Reply
  2. I have used the Hartz flea collars for years. Reading the negative comments(seizures, death) about side effects, I am worried. I also have 5 cats. Cost is a problem. Why do these things have to be so expensive??

    • When it comes to any flea drop or collar, every pet will react differently.

      It’s hard for anyone to be able to accurately predict what will happen to your pets come into contact with the chemicals.

      The best advice I can offer is to try one collar and keep a close watch on your pets until you know if they are having a reaction or not.

      As always, consult with your Vet before giving them anything!
