It’s not very well-known that fleas are highly-adaptable insects. They can even survive without eating for two weeks! That’s why getting rid of them can be quite a nuisance, even if you don’t have any pets. The good news is that there are many different flea killers available, and choosing the right one can make all the difference.

We’ve considered both sprays and powders because their application methods are vastly different, and so are their results. Active ingredients, such as permethrin or pyriproxyfen, have proven to be highly effective against fleas, so you should be looking for them if you want to see the best performance possible. If you’re looking for a milder, all-organic option, there are essential oil-based products. We’ve also considered how easy these flea killers are to use, how much smell they generate and whether they’re safe for children and pets.

  • Effective against: flea larvae and eggs, adult fleas and ticks
  • Active ingredients: 0.05% pyrethrins, 0.4% permethrin, 0.1% pyriproxyfen
  • Scent: medium chemical smell

The BASF Ultracide Pressurized Flea Insecticide is our Editor’s Choice because, in our opinion, it’s simply the best option on the market as of now. It’s incredibly effective against fleas in all life stages, as well as ticks, and it can prevent further infestation for up to seven months. When it comes to active ingredients, this spray contains 0.05% pyrethrins, 0.4% permethrin, and 0.1% pyriproxyfen – all of which are known to be effective against pests. Unfortunately, these chemicals result in a medium-strength smell, though we believe it’s worth the trade-off considering how well this product works. The BASF Ultracide Pressurized Flea Insecticide comes in a 20 oz. can and is easy to use, making it a great option for those who want an effective flea spray that’s also user-friendly and pet-safe.

Both the BASF Ultracide Pressurized Flea Insecticide and the Virbac Knockout E.S. Area Treatment Carpet Spray contain permethrin. Additionally, these chemicals can stop pest reinfestation on your carpet and upholstery for up to seven months. However, the former comes with a volume of 20 ounces while the latter has a volume of 16 ounces.

    What makes it special?
  • This product demonstrates incredible effectiveness against fleas
  • 20 oz. is plenty of product, making this a great value for the price
  • Although there is some chemical smell, it's not too overwhelming
    What cons did we find?
  • Not found

And, even though there’s a noticeable odor chemical smell right after application, this product is odorless after drying, making it ideal for homes with children or pets. Even though this product is a tried-and-tested option, some users report that a single application was not sufficient and that they needed to reapply the product at least one more time in order to achieve desired results. Nevertheless, the Virbac Knockout E.S. Area Treatment Carpet Spray remains a popular choice for many homeowners looking for an effective flea killer.

The Virbac Knockout E.S. Area Treatment Carpet Spray and the PetArmor Home Carpet Powder for Fleas and Ticks on our list are similar since they can prevent flea infestation on your carpet for a period of up to seven months. The main difference between the two chemicals is that the Virbac Knockout E.S. Area Treatment Carpet Spray produces a mild smell immediately after application. However, the smell goes away once it dries. PetArmor on the other hand has a clean fresh scent.

    What makes it stand out?
  • This product's formula has proven to be effective against fleas
  • Once applied, you'll only notice a mild chemical smell that quickly dissipates after drying
  • Stainless formula is great for carpets and upholstery
    Which disadvantages must you keep in mind?

Affordable Choice

Hartz UltraGuard Plus

Features
  • Type: spray
  • Effective against: fleas, ticks, flea eggs, flea larvae and pupae
  • Active ingredients: 0.4% phenothrin, 0.015% pyriproxyfen, 1.0% piperonyl butoxide
  • Scent: fresh
  • Volume: 16 oz.

Other features: eliminates odor, prevents reinfestation

Hartz UltraGuard Plus is an affordable spray that is effective against fleas, ticks, flea eggs, flea larvae and pupae. Active ingredients of this products include 0.4% phenothrin, 0.015% pyriproxyfen, 1.0% piperonyl butoxide and 1.0% N-octyl bicycloheptene dicarboximide. This product also eliminates odor and prevents reinfestation. Even though the manufacturer claims that this product has a fresh smell, we and other users found it rather strong and overpowering. Otherwise, this 16-oz. bottle will last you for a while and will effectively kill fleas on your carpet.

The Hartz UltraGuard Plus and the BASF Ultracide Pressurized Flea Insecticide are pet safe but not to be used directly on pets. They are also both spray flea killers for easier application. However, there is a difference in that when Hartz eliminates the entire lifecycle, BASF is only effective against flea eggs, larvae, and adult fleas. It does not work on flea pupae.

    Why are we impressed?
  • Affordable price for a decent volume of product
  • Proven effectiveness thanks to the presence of phenothrin, pyriproxyfen, and piperonyl butoxide
    What negatives must you be aware of?

Things to Consider

When buying a flea killer for your carpets, there are a few things you need to take into consideration. The first is whether you want to use a spray or a powder. Not only these two are applied differently, but there are also different precautions that need to be taken when using them. Next, you’ll need to decide what active ingredients you want in your flea killer. While most flea killers contain potentially hazardous chemicals, there are multiple natural or at least less harsh chemical options available. Last, but not least, the smell might be crucial if you have sensitive nostrils or children and pets in the house. Finally, all these factors should be looked at through a prism of your and your pet’s safety. Let’s take a deeper dive and find which products you should look for.

Spray vs. powder

Flea sprays are a common choice for getting rid of fleas in the home. They come in both aerosol and pump-spray bottles and can be applied directly to the carpet. These are usually more practical for small areas and for spot-treating. The application process is also easier since you don’t have to worry about getting the powder evenly distributed and then vacuuming it up.

Powders are another popular option for killing fleas in carpeted homes. They work by dehydrating the fleas and their eggs, which kills them. The powder is applied to the carpet and then vacuumed up after a few hours. This is a good choice if you have a large area to treat or if you want to make sure all the fleas are gone. Unfortunately, using powders can be tricky since you have to be careful not to inhale them.

There is no definitive answer as to which method is better. It really depends on your individual situation and preferences, as well as the size of the area you’re treating and the amount of work you want to put in.

To get rid of fleas, you might need multiple treatments. We recommend taking a look at the best flea bombs and foggers for house to help get rid of these pests once and for all.

Active ingredients

5 Best Flea Killers for Carpet That Will Protect You, Your Pet, and Your Home (Winter 2023)
Even though most flea killers use harsh chemicals as their active ingredients, there are also organic options that use such essential oils as lemongrass oil

There are a few chemicals in flea killers that work best on carpets. These ingredients include:

  • Pyrethrins: They are an insecticide that comes from the chrysanthemum flower. Pyrethrins work by attacking the nervous system of the fleas, and they can be very effective in getting rid of them. However, they are also toxic to pets and humans, so it is important to use them carefully and according to the instructions on the product.
  • Permethrin: It is a synthetic chemical that is used as an insecticide and acaricide. It belongs to the family of pyrethroids, which are a class of chemicals that are derived from the natural insecticide pyrethrum. Permethrin is effective against a wide variety of pests, including fleas, ticks, lice, and spiders. It is available in both spray and powder form and can be used indoors or outdoors. When used as directed, permethrin is safe for both people and pets.
  • Pyriproxyfen: It works by blocking the development of the flea’s eggs, which prevents them from hatching. This chemical is commonly used in combination with other pesticides to increase its effectiveness.
  • N-Octyl bicycloheptene dicarboximide: This chemical is also known as SENTRY, and it is a flea killer that is specifically designed to kill fleas on contact. It is a non-toxic and biodegradable powder that can be safely applied to carpets, furniture, and other areas where fleas are known to reside. SENTRY works by breaking down the flea’s exoskeleton, which causes them to dehydrate and die.
  • Sodium lauryl sulfate, or SLS: It is a common ingredient in many flea killers for carpets. It is a detergent and surfactant that helps to dissolve the oils and dirt that fleas rely on for sustenance. SLS is also a powerful irritant and can cause skin and eye irritation in humans and pets.

Besides such chemicals, flea killers may also contain essential oils, including:

  • Cedarwood oil: Cedarwood oil is a powerful flea killer. It is also effective against other insects, such as ticks and mosquitoes. It is made from cedarwood trees and has a strong smell that many people find pleasant. Cedarwood oil is safe for use around children and pets.
  • Lemongrass oil: Lemongrass oil is a natural flea killer that can be used to get rid of fleas on your carpet. It is a safe and effective way to get rid of these pests, and it is also a non-toxic way to keep your home free of fleas. Its smell is very unpleasant to pests but is pleasant to humans.
  • Sesame oil: Sesame oil is another essential oil that is completely safety people and pets. It has natural flea-killing properties that can be used to kill fleas on your carpets. When it comes to the scent, it has a nutty smell that can be a bit strong for some people.

Smell

Flea killers come in a variety of different forms, but they all have one common goal – to eliminate fleas from your home. However, while they may be effective at getting rid of fleas, many of them have a strong chemical smell that can be overwhelming.

When it comes to sprays, they tend to be the worst offenders when it comes to smell, especially when applied and not fully dried out. Once dried out though, most sprays will have little to no odor, so it’s recommended to use them in well-ventilated areas and isolate kids and pets from the area until it’s dry. Powders, on the other hand, have a very distinct smell that can linger for days, even weeks if not properly vacuumed up.

Safety

When using any type of spray or powder to kill fleas on your carpet, be sure to follow the instructions carefully and take all necessary precautions. Many of these sprays are highly toxic and can be dangerous if used incorrectly. Always keep children and pets away from the area that has been treated and avoid breathing in the fumes. Make sure to ventilate the room well before returning. If you’ve got spray on your skin, wash it off immediately and seek medical attention if you feel ill.

If you’re looking for safer ways to get rid of fleas, you may opt for flea traps. We have a comprehensive guide for the best flea traps, so check it out.

Life Cycle of a Flea

5 Best Flea Killers for Carpet That Will Protect You, Your Pet, and Your Home (Winter 2023)
There are four life stages of a flea, and it’s important to find a killer that’s effective against fleas in every of them

Fleas are small, parasitic insects that feed on the blood of mammals and birds. They can be found on pets, carpeting, and furniture. Fleas can cause skin irritation and lead to the transmission of disease. Fleas are reddish-brown insects that are about 1/8 of an inch long. They have a life cycle that includes four stages: egg, larva, pupa, and adult. To inhibit the life cycle of a flea, you might use one of the best IGRs for fleas we’ve selected.

Egg

Flea eggs are very small, oval-shaped, and translucent. They are often difficult to see with the naked eye. A female flea can lay up to 50 eggs per day. These eggs fall off of the host animal and into the environment, where they hatch within 2-12 days. Getting rid of flea eggs is essential to breaking the flea life cycle.

Flea killers that work for eggs are typically insecticides that contain pyrethrin or permethrin. These chemicals kill flea eggs on contact. You can also use a vacuum to remove flea eggs from your home. Be sure to dispose of the vacuum bag afterward to prevent the eggs from hatching.

Larva

Flea larvae are small and white, and they can be difficult to see. They are usually found in areas where pets sleep or spend a lot of time, such as on beds, couches, or carpeting. Flea larvae feed on the dried blood left behind by adult fleas. This can make them a potential health hazard for people with allergies to flea bites. To get rid of them, you will need to vacuum the area well and then use a flea killer.

Pupa

The pupa stage is a crucial part of the life cycle of a flea. During this stage, the flea will undergo a radical transformation from a larva into an adult. This process is necessary for the flea to be able to reproduce and lay eggs.

Fleas in this stage are often referred to as “cocoons” because they are wrapped in a silken cocoon. The pupa stage can last anywhere from two weeks to several months, depending on the species of flea and the temperature.

During the pupal stage, the flea will not feed. Once it has transformed into an adult, however, it will immediately begin to search for a host – typically, a mammal or bird. Once it finds a suitable host, the flea will bite and begin to feed on its blood.

Fleas in the pupal stage are very resistant to insecticides and other forms of treatment. This is why it is often difficult to get rid of fleas completely. If you are dealing with a flea infestation, it is important to treat all stages of the life cycle, not just the adult fleas.

Adult

Adult fleas are the most common type of flea and they can be found on both pets and humans. They are about 1/8 of an inch long and are reddish-brown in color. Adult fleas feed on blood and can cause a lot of discomfort for their hosts. They can also transmit diseases like tapeworms.

FAQ

Are fleas dangerous for pets?

Fleas can be a nuisance to pets, but they also carry a number of dangerous diseases. Some of these diseases can even be fatal to pets. Fleas are most commonly found on dogs, cats, and rabbits, but can also be found on other mammals. Some of the most common diseases carried by fleas include bubonic plague, typhus, cat scratch fever, and tapeworm infection.

What do I do if a flea bit me?

Fleas are dangerous for humans because they can transmit parasites and other diseases. They can also cause anemia in children and adults. If you’re bitten by a flea, it’s important to clean the wound and apply an antibiotic ointment to prevent infection. You may also need to take an antihistamine to relieve itching.

Where do fleas come from?

Fleas come from a variety of places, such as other animals, the environment, and other people. They can be very hard to get rid of, so it’s important to take steps to prevent them in the first place and to get rid of them as soon as possible if they do become a problem.

Your pet can get fleas from other animals, such as at the park, from the groomer, or even from another person’s house. The environment is also a common source of fleas, as they can live in grass, dirt, and bushes. If you live in an area with a lot of wildlife, such as near a forest or farm, there may be more fleas present in the environment. People can also carry fleas into your home on their clothes or shoes.

If you don’t have any pets and you have fleas in your home, they may have come from a person or animal who visited your home. Once fleas are in your home, they can quickly multiply and become a big problem.

Our verdict

Our top choice is the BASF Ultracide Pressurized Flea Insecticide due to its incredible effectiveness and longevity. Many users claim that this is the best product on the market, and we fully agree with them.

If you’re looking for a little bit more value, we recommend the Virbac Knockout E.S. Area Treatment Carpet Spray. This product is a little bit more affordable than our top choice, but there were not any sacrifices made when it comes to effectiveness and safety.

Finally, if you’re looking for a powdered flea killer, our choice is the PetArmor Home Carpet Powder for Fleas and Ticks. With its proven efficacy against flea and ticks and deodorizing properties for carpets, there’s no better powder on the market.
