Fleas can be irritating at the best of times, but if left untreated, they can cause discomfort and even lead to your cat developing flea allergy dermatitis. At the first sign of fleas, it’s a great idea to treat your cat using a flea spray so you can start getting rid of those nasty little critters. The important thing is to break the flea life cycle so your cat and home will be rid of all fleas, from adults to larvae and eggs, too!
There are plenty of flea sprays available on the market; the trouble is deciding which one is going to suit you and your cat best. Some sprays are designed for use on both your cat and home surfaces, while others should only be sprayed on your cat itself. There are versions using conventional pesticides and insect repellents, as well as natural alternatives that use plant-based extracts instead.
If you’re struggling to decide which flea spray to buy, our reviews can help you quickly and easily identify the best flea sprays for your cat.

The 10 Best Flea Sprays for Cats
1. Vet’s Best Cat Flea & Tick Home Spray — Best Overall
Vet’s Best Cat Flea & Tick Home Spray is our pick as the best flea spray for cats. It uses a formula specifically created for cats and contains 100% natural ingredients with no artificial colors, preservatives, or fragrances. It’s made right here in the U.S.A. with ingredients sourced domestically, and it comes in an easy-to-use spray bottle that makes it easy to apply where you need it. The plant-based formula kills living fleas and their eggs, and it is also effective against ticks.
The problem with Vet’s Best is that it can take a few applications to work, and some users report that they didn’t have success. Many customers also say that the spray bottle can be flimsy and break easily.
2. Hartz Nature’s Shield Cat Spray — Best Value
Hartz Nature’s Shield Cat Spray is our pick as the best flea spray for cats for the money. It kills fleas and ticks in all stages and works to repel mosquitoes, which can transmit worms and other harmful diseases. Many users report that it has a pleasant fragrance and is safe to use around children and pets. You can spray it on bedding and other areas where there are higher concentrations of fleas and even apply it directly to their fur, where it will provide vitamin E, which will help promote a shiny coat.
The only thing users of Hartz Flea spray don’t like is that it can take several applications to work effectively.
3. Harris Home Pest Control Flea & Tick Killer Spray — Premium Choice
Harris Home Pest Control Flea & Tick Killer Spray features proven insecticide ingredients like clove, cottonseed oil, and deltamethrin, which make it strong enough to use outdoors, while the water-based formula remains safe for your pets, even kittens and senior cats. The handy spray nozzle makes it easy to put it where you need it. It won’t stain and has no odor, so it won’t disrupt life in your home, and the large bottle means you won’t have to skimp when you apply it.
Unfortunately, Harris Home Pest is still quite expensive compared to most other options. Some users also complained that the bottle frequently leaks, which can result in you getting it in unintended areas.
4. Zodiac Flea & Tick Spray for Cats — Best for Kittens
Zodiac Flea & Tick Spray for Dogs, Cats, Puppies & Kittens is our pick as the best flea spray for kittens. It uses a dual-action formula that starts to take effect almost immediately, with pyrethrins to kill the adults and PRECOR insect growth regulators to kill the eggs and larvae. Another great feature of this product is that it continues to work for up to 2 months and is safe for kittens and puppies more than 12 weeks old. The spray bottle makes it easy to apply, and many users report that it works well.
The main problem with Zodiac flea spray is that it has a strong odor that many people don’t like, with some even claiming their pets didn’t like it. A few people also complained that despite the strong smell, it didn’t prevent new fleas from jumping on their pets.
5. Sentry Home Flea-Free Breeze Home & Carpet Spray
Sentry Home Flea-Free Breeze Home & Carpet Spray is a powerful water-based spray that you can apply to pet bedding, carpets, furniture, and more to quickly kill fleas and continue to do so for up to 7 months. The dual-action formula kills fleas and works on eggs. Most people claim that it works well overall and has a pleasant fragrance.
The downside to Sentry flea spray is that many people complain that the spray bottle is leaky and can cause skin irritations if it gets on you. That means it’s not safe to use on your pet, which makes many people afraid to use it at all.
6. Bayer Advantage Flea Treatment Spray
The Bayer Advantage Flea Treatment Spray contains pyrethrins, piperonyl butoxide, and MGK 264 Insecticide Synergist. This spray effectively kills adult fleas, lea larvae, flea eggs, ticks, and lice. The whisper-quiet spray is perfect for nervous cats and can be used upside down for those hard-to-reach areas on their bellies. It will also help combat flea bite dermatitis and keep fleas from maturing enough to reach the stage at which they bite.
A single application of this spray lasts an incredible 100 days, so while this is a little more expensive per ounce than some other flea sprays, you get value for the money! This spray can also be used to treat bedding, carpets, upholstery, and more, to help remove any fleas that may be on your cat’s bedding and other surfaces.
7. Wondercide Rosemary Home & Pet Flea Spray
The Wondercide Rosemary Home & Pet Flea Spray. This spray is made in the U.S.A. without the use of harmful chemicals. Instead, it harnesses the power of naturally derived plant-based ingredients, including cedarwood oil and lemongrass oil. It also has a fresh rosemary scent and is completely safe to use on your cat, dog, and all home surfaces. You’ll initially need to apply this every 2 to 3 days to gain control of a flea infestation, but the good news is that you can safely use this repeatedly without worrying about exposing your cat to harsh chemicals.
This biodegradable formula is made in the U.S.A. and is safe enough to use on kittens and adult cats. However, it can’t be shipped to the states of Indiana, Maine, South Dakota, or North Dakota due to the fact that the product label has yet to be registered with those states.
8. Pet Naturals of Vermont Flea + Tick Spray
The Pet Naturals of Vermont Flea + Tick Spray uses lemongrass oil, cinnamon oil, sesame oil, and castor oil to effectively repel fleas, mosquitoes, flies, and ticks. This spray is made in the U.S.A., using a combination of natural plant-based ingredients inspired by the indigenous people of the Amazon rainforest. Rather than killing fleas, this spray creates a scent across your cat’s coat that is undesirable for these critters, so they should be discouraged from staying on your cat.
You may need to use this with another topical flea spray if you have an extreme infestation and want to kill fleas, as well as repel them. The good news is that thanks to the natural ingredients, this spray is safe to use on kittens of any age, unlike some other sprays that can’t be used when they’re very young. This spray has a lemongrass scent, which some cats and their owners may find strongly off-putting.
9. Ark Naturals Flea Flicker! Spray
Ark Naturals Flea Flicker! Spray harnesses the power of essential oils geraniol, eugenol, and peppermint to naturally repel fleas, ticks, and mosquitoes. If your cat has skin sensitivities to traditional flea sprays, then this natural alternative might be the answer. Many natural sprays use citronella, cedarwood or leaf oil, and lemongrass, all of which can cause skin irritation.
This spray will only repel rather than kill fleas, so you may need to reapply this spray multiple times before you notice the number of fleas starting to decrease. Any flea larvae or eggs that are already on your cat or in your house will mature and grow into adult fleas before being affected by this spray. While it does use natural ingredients, it does have a strong scent that can be a little off-putting.
10. Natural Chemistry Natural Flea Spray
The Natural Chemistry Natural Flea Spray uses a blend of cinnamon oil, clove oil, cedarwood oil, and vanillin to kill adult fleas on contact. It uses natural ingredients, although some users may find the smell to be quite strong. This spray is safe to use every 7 days, which is good because you may need to reapply this frequently over a month or so to kill any eggs and larvae that mature into adult fleas.
It can be used at the same time as a topical treatment, which may be a good combination to ensure that larvae and eggs are also killed while this spray controls adult fleas. This is only available in a small 8-ounce spray bottle, which will end up being used quickly, especially with the frequent re-applications that are recommended for best results.
Buyer’s Guide: Finding the Best Flea Sprays for Cats
With so many flea sprays out there to choose from, it can be a little confusing to figure out which one will suit your cat best. We put together a handy buyer’s guide to help you decide.
Why use flea spray?
Some cats hate taking flea tablets or can develop irritation from topical flea applications. In these cases, using a spray can be a great alternative. Most cats will be happy to stand while you cover their coat with a light coating of spray, especially if you offer them treats at the same time!
How do flea sprays work?
This depends on the types of active ingredients used and their concentration. Some flea sprays contain insecticides that kill all or some life stages of fleas. Others contain Insect Growth Regulators (IGRs) that interrupt the flea life cycle by preventing larvae and eggs from maturing into adult fleas. Other flea sprays contain plant-based ingredients, like essential oils, that kill some or all life stages of fleas. Lastly, some plant-based flea sprays contain essential oils that are designed to repel but not kill fleas. These basically cover your cat’s coat in a smell that is unpleasant for fleas, so they’re less likely to stay on your cat’s coat to lay their eggs and bite your cat.
Ingredients: Natural or chemical?
Traditional chemical flea sprays are usually safe and extremely effective. Some of them can cause localized skin irritation if they’re used too frequently. Natural flea sprays contain plant-based ingredients, including cedarwood oil, lemongrass, and citronella. These may not be as effective at killing fleas as sprays containing insecticides or IGRs, but the choice comes down to your personal preference and which ingredients you’re happy to use.
Can I use flea spray on home surfaces?
If your cat has fleas, there’s every chance that their bedding and your home surfaces have flea eggs on them. As these mature into adult fleas, the cycle of infestation continues. So, as you treat your cat for fleas, you’ll need to also treat surfaces, like your cat’s bed, carpets, soft furnishings, and anywhere else that your cat may sleep or hang out on a regular basis.
Some flea sprays are also suitable for use on home surfaces, but you should always read the label of your preferred product to make sure this is the case.
Can I use other flea treatments at the same time as flea spray?
If you’re battling a flea infestation and looking at ways of quickly controlling the situation, you might be tempted to use other flea treatments at the same time as flea sprays. This is possible with some products, and there are plant-based formulations designed to work concurrently with topical treatments without interfering with their effectiveness.
If you want to use multiple flea treatments at the same time, always consult your vet and let them know which products you want to use together and the active ingredients that these contain. They can advise you whether it will be safe to do so.
Are flea sprays waterproof?
Some are, and some aren’t. Always read the label to check if the product that you’re using is waterproof before giving your cat a bath! Our best overall pick is waterproof and resistant to sunlight, so after application, it lasts for a full 30 days, no matter what your cat is doing or where they’re going!
How do I apply flea spray?
Always read the manufacturer’s specific instructions first. As a general rule, you’ll want to spray against the lie of your cat’s coat so the flea spray penetrates their fur and can make contact with their skin and the roots of their hair. Place your cat on a table or other raised surface, and brush their coat the wrong way with your hand. Spray the flea spray just behind your cat, where their coat is raised. Repeat until your cat’s entire coat is damp. Avoid their genitals, eyes, ears, and mouth. If necessary, you can spray a small amount of the liquid onto your hand and gently apply this around their face. If you have sensitive skin, we recommend wearing gloves.
When choosing a flea spray for cats among these reviews, we highly recommend our pick for the best overall. Vet’s Best Cat Flea & Tick Home Spray uses a formula specifically created for cats that uses 100% certified all-natural ingredients. Hartz Nature’s Shield Cat Spray is our pick as the best value, and it kills fleas and ticks while replenishing your cat’s coat. Harris Home Pest Control Flea & Tick Killer Spray is our premium choice and is extremely effective with time-tested pesticides while remaining safe to use around your pets. We hope that one of these products will work for you and your cat!
