Fleas are everywhere. Some live on your pet where they lay eggs until they die. Most, however, live in our floors, backyards, fixtures, bedding, upholstery, and even the carpet where our pets frequently stay. One of the most important ways to effectively rid your home of these ectoparasites is by cleaning and treating the whole house. You can start with these 6 best flea spray and flea powder products you can easily apply to your carpet to kill those pesky little jumpers before you start vacuuming them for more efficient disposal.

The 5 Top-Rated Flea Carpet Spray & Powders

1 Knockout E.S. Area Treatment Carpet Spray By Virbac

Knockout E.S. Area Treatment Carpet Spray By Virbac
Key features:
  • Contains Nylar, permethrin, and pyrethrins
  • Kills adult fleas, eggs, and larvae up to 7 months
  • No unpleasant smell
  • Doesn’t stain

The Virbac Knockout E.S. Area Treatment Carpet Spray is one of the most trusted products when it comes to flea carpet sprays. It contains the pyriproxyfen Nylar which is an insect growth regulator. It doesn’t really kill fleas on contact but severely disrupts their ability to grow. This effectively stops the flea life cycle while also making them more vulnerable to the other active ingredients of Knockout, pyrethrin and permethrin.

These two substances are what kill adult fleas (like our products in our guide for the best flea treatment for dogs,) eggs, and larvae. Since it is available in aerosol form, it can easily penetrate hard-to-reach areas where larvae are known to hide. It doesn’t leave any stains or even nasty odors in your room so you can feel more confident about using the product to keep these pests out of your home.

What others say about it:

This product is the absolute best. We use this at our vet clinic, it is a bit pricy through my vet so i ordered it here and the price was just right. It works great especially if your pet has fleas and you need to help kill off fleas around the house. Great product.

2 Flea & Tick Pet & Home Spray By Vet’s Best

Flea & Tick Pet & Home Spray By Vet’s Best
Key features:
  • Contains peppermint oil and eugenol from cloves
  • Pyrethrin- and cedar oil- free
  • Multi-surface application
  • Kills adult fleas and eggs

For individuals who don’t like the idea of using chemicals as insecticides, Vet’s Best’s Flea & Tick Pet & Home Spray is a great choice. The product features two proven natural substances that can kill adult fleas and eggs. The same formulation can also help repel other insects like mosquitoes that bring other disease-causing germs. The only downside, of course, is that it doesn’t affect the larval and pupae stages of fleas so you may want to apply another method for it.

Nevertheless, the Vet’s Best offers exceptional versatility as it can be sprayed onto any surface and not just your carpet. You can even apply it directly on your pet’s coat. It doesn’t contain pyrethrins so you can spray it safely on your cat’s fur as well. Vet’s Best is simply perfect for those who are wary of using synthetic chemicals in their homes, not only for the safety of their pets, but more importantly their family’s personal safety.

What others say about it:

This product smells nice, though it’s very strong at first, and works very efficiently and very quickly. I sprayed it in my home and on my dog and had less fleas within a short period of time.

3 Flea & Tick Carpet Powder By Adams

Flea & Tick Carpet Powder By Adams
Key features:
  • Contains Linalool, Nylar, and pyrethrins
  • Comes in fresh citrus scent
  • Kills adult fleas, eggs, and larvae
  • 365-day protection against fleas

Adams’ Flea & Tick Carpet Powder is uncannily similar to the Bio Spot Active Care in all respects including the active ingredients, its powder formulation, and the length of time of its insecticidal effects. Regrettably, it also shares the same negative experiences of some pet owners who have already used the product, saying it doesn’t really kill fleas even if they followed the directions of application to the letter.

It does come in a fresh citrus scent, however; so that should be a consolation in itself. It really is not easy to identify the failure of insecticidal activity experienced by some pet parents since there are also those who can attest to its effectiveness as a flea exterminator. So you might want to consider this if you’re into combining natural and synthetic into a powdered form of flea control.

What others say about it:

Works very well in area that are not great for spraying like carpeted rooms and throw rugs. With in 24 hours fleas are pretty much eradicated.

4 Carpet And Upholstery Aerosol Spray By Zodiac

Carpet And Upholstery Aerosol Spray By Zodiac
Key features:
  • Contains s-methoprene and permethrin
  • Kills adult fleas, eggs, and larvae
  • Water-based, fast-acting, pet-safe formulation
  • Long-lasting protection up to 7 months

One of the most annoying things about most flea carpet sprays is that they are mostly oil-based. The Zodiac Carpet and Upholstery Aerosol Spray is 100% water-based so you can feel more confident about not leaving any telltale odors on your carpet as well as other surfaces you’re going to spray the Zodiac on.

In addition to the insect growth regulator s-methoprene, Zodiac also contains 2 of the most common insecticides used in managing fleas and ticks. This gives the Zodiac the ability to kill adult fleas, larvae, and eggs on contact, while making sure that your surfaces stay protected up to 7 months. You will surely miss the 365-day protection afforded by Bio Spot and Adams, though. Nonetheless, with is fast-acting and longer-lasting formulation, 7 months is still a good feature.

What others say about it:

I have several feral cats that dine at my house. When they arrive, they bring their friends during flea/tick season! I found this product several years ago, and it is the solution to any flea or tick problem. 1 can of this spray covers 2100 square feet from a fine mist you apply as you move from the far side of each room to the door. The spray contains an instant kill chemical and a long term kill chemical. Once it dries the room is safe for kids and pets. the long term chemical is a growth inhibitor that won’t allow eggs to hatch or pupa to form into a flea or tick. And it lasts 210 days, the full flea season!

5 Flea Killer Plus Carpet & Room Spray By Raid

Flea Killer Plus Carpet & Room Spray By Raid
Key features:
  • Contains pyrethrin, tetramethrin, and s-methoprene
  • Kills adult fleas, eggs, and larvae up to 4 months
  • CFC-free formulation
  • Works well on carpets, upholsteries, and pet beddings

Raid is best known for its mosquito and cockroach sprays. What many don’t know is that they also have flea and tick sprays such as the Flea Killer Plus Carpet & Room Spray. The Raid formulation comes with 3 different insecticides plus a synergizing element that helps improve the overall insecticidal activities of these three active ingredients. The other good news is that you can actually spray the Flea Killer Plus even with the aerosol can inverted upside down.

Most aerosol sprays require you to spray with the can held upright. Together with its unique wide-angle spray design, you can cover more ground in fewer passes. Our only wish is that Raid improves on the length of insecticidal activity of the Flea Killer Plus. Offering only 4 months of protection, the Flea Killer Plus’ insecticidal activity is the shortest in this list. Regardless, spraying 3 times a year is still better than spraying monthly.

What others say about it:

Have always used this because it works and doesn’t smell too bad either. One can does not eradicate all the fleas. Two works for me, but you have to be keep up on them.

The Best Flea Carpet Spray & Powders: Buying Guide

It is easy to buy a flea carpet spray or powder from your local pet shop. But if you’re looking for something that is both safe and effective, then you really have to study carefully the product that you want to buy. Here are a few of the more common concerns that buyers of flea carpet sprays and powders have. Hopefully, these will help you determine the best product to use on your carpet and other items at home.

Can Flea Spray Kill Fleas Immediately?

Depending on the active ingredient or ingredients used in the formulation of the flea carpet spray or powder, fleas can be killed almost instantly on contact. For example, those that contain pyrethrins can kill fleas almost immediately upon exposure since these ingredients produce seizures in the flea’s nervous system, causing death. Products that contain permethrin, a broad-spectrum insecticide, can also kill fleas immediately. Permethrin is also sprayed or embedded onto fabric to give clothes some form of insecticidal property, especially against mosquitoes and ticks. Technically, if you use products that contain these chemicals, then you are most certainly guaranteed instant flea-killing effects.

However, if the product contains insect growth regulators like pyriproxyfen, better known as the Nylar brand, and s-methoprene, you will not be able to kill fleas on contact. These insecticides exert their insecticidal activities by either adversely affecting the various hormonal systems involved in insect molting or preventing the synthesis of a crucial element in the insect’s exoskeleton. Technically, what these chemicals do is that they weaken the protective defenses of fleas and other insects so that they will be more susceptible to environmental factors such as temperature and humidity as well as on the activity of other insecticides.

Then there are also those that neither kill nor alter the growth of fleas. Instead, these chemicals emit a very strong scent or they produce an environment upon which fleas simply don’t want to go. These chemicals make such environments intolerable for fleas so they won’t go near such environments. These chemicals are better known as insect repellents.

How to Properly Use Flea Spray and Powder

Vacuum Cleaner Cleaning Dirt On Carpet

Even before you start applying flea carpet sprays or powders it is often wise to make preparations first. Ideally, you would want to clean the entire room that you are going to apply these flea products on. Make sure to use a vacuum cleaner that comes with a crevice tool attachment since what you would want is to remove flea larvae that typically hide in cracks, crevices, holes, gaps, and other areas where there is sufficient shade from light. Vacuuming can also remove flea eggs, pupae, and adults that may be present on your floor, upholstery, pet beddings, rugs, and carpets. Make sure to dispose of the vacuum bag immediately without having to empty its contents into another receptacle.

Once you’ve thoroughly cleaned the room, sprinkle flea powder across the surface of your carpet or even upholstery. Get a broom and lightly brush the surface of the carpet to allow powdered granules to reach the very bottom of the carpet pile. If you’re applying it in upholstery, make sure sprinkle powder into the corners as well as along creases and folds. These are the areas where fleas would normally hide.

Leave the application for at least 60 minutes, although for better results you may want to leave it untouched for the next 24 hours. After 60 minutes or 24 hours, whichever you are going to use, vacuum your carpet as well as any other surface that you sprinkled with the flea powder. This will remove excess powder that may be left on the superficial layers of your carpet or upholstery.

Further Instructions for Flea Spray & Powder

If you’re using flea carpet sprays make sure to shake the aerosol can thoroughly before application. Spray in an inconspicuous area of your carpet or upholstery to check first if the formulation will not react with the fabric. If it doesn’t, then you can proceed to spray the rest of the item.

Position the nozzle of the aerosol spray some 2 to 3 feet away from the surface of the carpet. Make sure to move in a sideways direction avoiding oversaturating any given area. Keep in mind that you have to be methodical and systematic in your flea carpet spray application. Any missed area will significantly affect the overall effectiveness of the application. Leave the upholstery or carpet untouched for a few hours up to 24 hours before you can allow your pet to start using it again. This is to allow any residue from the chemicals used in the product to dissipate completely into the surrounding air.

Things to Consider Before Choosing a Flea Spray

Generally, even before you start choosing a flea spray or powder, there certain things that you really have to think about.

  • The severity of Flea Infestation

It is important to determine if you have severe flea infestation or not. The reason why this is very important is that using flea spray or powder alone will not really help you get rid of these pests that easily. You will require a more multi-faceted approach to controlling flea infestation. The use of flea sprays is only one aspect of flea control programs.

  • Kill or Repel?

What do you want to achieve? Do you want to kill fleas across the various life stages? Or do you simply want to repel them? This is closely related to the severity of flea infestation in your home. If it is not really that severe and you only occasionally encounter fleas as a problem, then perhaps a flea repellent spray is a much better option than one that is an insecticide. But, if your problem is severe flea infestation, then you would want to kill as many fleas as possible.

  • Availability of Other Means of Flea Control

Do you have other means of controlling fleas? Remember, using flea sprays also has its limits. Some of these products cannot be applied directly onto your pet. There are also other considerations such as if you have other pets that might be harmed during the spraying of the product. As such it is imperative that you explore other means of flea control.

  • Natural or Synthetic?

There are products that contain only natural ingredients while most contain synthetic chemicals. Although safer, natural insecticides may not be as effective as synthetic chemicals. The reverse can be said of synthetics. They can be especially effective, but their safety profile may not be that sterling either.

  • Health Status of Your Family

The main issue with flea sprays is that most contain synthetic chemicals. These are insecticides that you spray over surfaces that can have serious implications to your health or the health of your family such as those who are vulnerable to the development of respiratory and allergic conditions. Do study carefully the active ingredients listed in product labels so you’ll be better informed as to their effects on your and your family’s health.

  • Does It Pose Any Health Risks?

All chemicals, whether it is naturally synthesized or manmade, can have adverse effects on those who are especially susceptible to such substances. Both humans and pets can show potentially dangerous reactions because of the use of products such as flea powders and sprays.

For example, permethrin is believed to have the potential to cause liver and lung cancer while also possibly disrupting endocrine function in susceptible animals. Its nerve-irritating activity can also produce tremors as well as the possibility of aggression in pets and learning difficulties.

Pyrethrin, on the other hand, is a very potent insecticide. While it is highly valued because of its unusually fast degradation in the environment, its unique chemical structure makes it particularly toxic to animals as well as humans. There have been reports of young children having been exposed to flea shampoos that contain pyrethrin which led to an asthmatic attack within 2.5 hours after pyrethrin exposure.

One needs to understand that these health risks are present because of the means by which these products are applied. These are either sprinkled or sprayed onto surfaces that we and our pets often use. It is good if we aren’t susceptible to such chemicals. But what if we weren’t?

Flea control requires a concerted effort that includes managing the environment upon which these pests can possibly hide. Such is the goal of using flea carpet sprays and powders. However, it is important to realize that this is just one aspect of flea control.
