Adams Carpet Powder Review

Adams is a leading brand in the pet care industry that takes a smart and effective approach to pet care solutions. Its primary goal is to make protecting families and homes easier and even more effective. A good number of Adams’s products have been sold to many customers by veterinarians for well over 30 years and they include tick and flea topical products; collars and sprays for homes, dogs, cats, and puppies. In fact, you are likely to find just about any type of pet care product you want by shopping Adams’ range of products.

A flea or tick infestation is probably one of the most annoying experiences you can have a home and/or a pet owner. And the search for the best flea powder is a kettle of fish on its own. This is why we decided to do thorough research on Adams’s products and recommend its Flea and Tick Carpet Powder.

This flea rug powder kills fleas at every single stage of the life cycle – from the eggs to the larvae to the pupae and adult stage. It also has the ability to break a cycle and leave a control and prevention effect that can last up to a year.

This means that once you do a thorough application of this powder in target areas in your home and vacuum it, you won’t need to keep re-applying to get rid of the pests.

Moreover, a 16-ounce can of this powder can treat areas that measure up to 200 to 400 square-feet effectively. So, if you have a larger space to cover, you may need to consider buying more than one can.

It also has a fresh citrus scent that swallows up foul smells in the home while the active agents in it go on a killing spree.

Its active ingredients include Nylar, which regulates insect growth and Linalool – an insecticide that is derived botanically.

According to the manufacturers, this product is not safe for kids and pets. So, we advise you to apply caution while using it. Even though some pets don’t show allergic reactions to it, we prefer that you are safe rather than sorry.


  • Active ingredients: Linalool, Nylar, Pyrethrins, Piperonyl Butoxide
  • Target insects: Fleas, flea eggs, flea larvae, and ticks

Bio Spot Active Care Powder Review

“Care for your pet, from nose to tail.” Bio-spot wants to help pet parents do just that because it believes that just like with the bond between a mother and child, a cat or dog is special to its owner, and deserves special care. Like a mother’s love, a pet’s love is unconditional so Bio-spot believes that the key to a happy home is a healthy, active, flea-free pet.

Bio-spot’s famous 3-step key to preventing pest infestation is simple; protect, prevent, and defend. Using the specially formulated Bio Spot Active Care Powder, dog owners should protect pets from pests and prevent a new infestation so pests don’t hitch a ride into your home (and the effect lasts for as much as 3 months). Then using in hiding areas, defend your pets (and yourself) by eliminating ticks, fleas and other bugs.

Because killing only the adult fleas and leaving the eggs and larvae lying around is merely scratching the problem at the surface, Bio-spot’s flea and tick carpet powder work to kill fleas in all four phases of the lifecycle so you can be sure that you have no live eggs, larvae, or pupae hanging around. If you proactively use the flea and tick powder Bio-spot guarantees that re-infestation will be kept under control for a full year.

As far as the relatively non-toxic options go, this is one of the best flea powder for carpets you may find. All you need to do is apply it to the carpet, let sit for a while and then vacuum the carpet as you would normally. And this flea treatments will kill fleas on contact and leave no more fleas to bother you or your pets.

The dust comes in handy with the purchase of a new home (don’t wait for the first bite before you treat) as sprays don’t really work well in scenarios like this. Leave it in before and vacuum before you move in and you can be sure you won’t see a flea. That said; also prepare for some real cleaning because things can get very dusty. Warning: wear a mask, especially if you have sensitive eyes or nose.

Even though you may have to wash countertops and exposed surfaces using this powder because the dust gets everywhere, despair not. It only means that cracks and crevices have been thoroughly flushed too.

Zodiac Flea & Tick Powder


What we like :

What we don't like :

  • While it says you can use for kittens, you can’t really use it for dogs younger than 12 weeks old.

Zodiac Flea & Tick Powder Review

Think lawn, garden, and pets; think Central Garden & Pets. This company has been around since 1980 and hasn’t stopped hitting the public with innovative, quality service. Central’s brands have become recognized by consumers and even industry peers for this innovation. If you use Altosid mosquito problems control products, you already know you are in good hands with this Flea and Tick Powder.

This wide range flea control powder helps keep your pets and home free from pests. It is known to control fleas, lice and tick. And with its pleasant smell, even outdoor cats won’t mind a little touching up with this powder. This means that you can put this on the dogs before you run them in the woods and rest assured that no ticks will hitch a ride home.

Central really thought this product through. To make sure you have no difficulty dispensing the powder, Zodiac Flea and Tick Powder come with a shaker top (talk about innovation). The fast killing action means you never get to wait days for those pesky little buggers to stop biting you. Not only does it kill fast, it makes sure that the problem is kept at bay with its effects lasting a long long time.

If you’ve ever fought a battle against fleas and lost, you know that while you are weary, exasperated, and tired of fighting the same battle all the time, you really can’t give up. Ever. Zodiac Flea & Tick Powder, however, is guaranteed to make sure you don’t lose even if your fleas have become immune (easy with pets that come and go as they please). It may take a little time but there should be a difference between the first treatment and with the second one, they should be totally gone. From then on, it’s once a month for you and your cats.

Interesting fact: Zodiac was determined by Second Chance Wildlife to be the gentlest way to treat fur-covered babies, ill, old animals. It works and it’s less toxic; so they said. Of course, you have to still apply it carefully; important to keep away from eyes, nose, and mouth; or any open/healing wounds but If there is a homeopathic product out there that is way less chemical and as effective, it apparently hasn’t been discovered yet.

Durvet Carpet Spray


What we like :

What we don't like :

  • Although it works really well, it has a very strong not-so-nice odor.

Durvet Carpet Spray Review

Starting very small, Durvet’s eventual success in the healthcare industry is proof that passion in business surely means exceptional products and hence, loyal customers. Durvet, apart from its 20 independent shareholding distributors whose sales run in billions annually, makes a whopping $200 million from the sales of its animal health and care products per year, keeping pet owners happy and coming back for more with impressively performing products and the affordability they require.

Used indoors to kill adult fleas, ticks, and even larvae, the No Bite IGR House & Carpet Spray is the Amazon’s Choice flea killing powder. One container should last approximately 3 months in a 1500 square foot home if you spray along baseboards, area rugs, furniture, and pet bedding, and it isn’t harmful to house plants.

For the dog or cat lovers, this is a dream come true. Spraying on the dog bed after washing quickly gets rid of the fleas, ticks and literally all bugs. And the formulation of the powder is such that it reaches into hidden cracks and crevices, the eggs aren’t allowed to turn into insects, and the little ones stop growing; it’s a growth inhibiting hormone formulation. The effectiveness of the powder lasts for three months because of this. When other flea killing carpet powder can’t stop fleas from breeding in your couch and carpet, one application of No Bite takes away their pesky little lives and their power to bite. Seriously this is easily one of the best flea powder for carpets on the market.

The smell may be horrible but only lasts a short while; a few hours tops. If you are in the market for something that works better than flea bombs, this should be just right. You just have to let it sit for a while after spraying so it gets the chance to work, vacuum every day and throw the bag away otherwise the fleas just crawl back out. You should also spray inside the vacuum for some added flea killer effect.

Even if you don’t keep any pets, what do you do when guests come with flea-infested bags (even if you didn’t notice them then, that could well be the reason for your infestation weeks after they leave)? Thanks to Durvet, you don’t have to worry about that. Your granddaughter doesn’t have to say a teary goodbye to her little pup whenever she comes visiting you, and you don’t have to endure flea bites when she asks so nicely to bring him either!


  • Active ingredients: Pyriproxyfen, Tetramethrin, Phenothrin
  • Target insects: Fleas, Ticks, Flea eggs, and Larvae
  • Where can be used: Indoors
  • Other features: Quick action, long lasting

Owning over 1500 products with more on the way, Hartz continues to teem with newer and better ideas for engaging pets and keeping them in health with quality and creative products that range from ergonometric leashes to advanced flea and tick protection, to imaginative toys.

First of all, it is rapid. It kills fleas in carpets and rugs in a very short time. And not just fleas alone, this powder is equally potent against ticks too.

When applied, this flea carpet powder doesn’t just kill adult fleas, it also destroys their eggs and larvae and we know this is good news because it means longer and more permanent protection for us and ours.

Fleabusters Rx Powder


What we like :

What we don't like :

  • A few customers seemed to have issues with applying the product. It appears that the powder is really fine and can work up quite the dust storm while applying. Our advice? Get a dust mask.

Fleabusters Rx Powder Review

Fleabusters has, for over 20 years, been saving homes and carpets with its array of products of which the Fleabusters Rx for Fleas is a prime example. Registered with the Federal Environment Protection Agency as well as other state agencies, its products have been approved to be both effective and safe for use in all states across the US.

If you’re tired of fleas calling the shots in your home, then its time you got the Fleabusters Rx for Fleas. We are confident about putting this particular flea carpet powder on our list because its mechanism is not only effective, it is also very genius.

A little bit of a science lesson now. Fleas are very sensitive to extreme pH values. So, naturally, if the pH of a certain place is, say, acidic or alkaline, the fleas will sense it and consequently avoid. But here’s what makes Fleabusters Rx for Fleas stand out, it comes with a neutral pH of 7.

Because fleas cannot sense this neutral pH, they unsuspectingly walk through and of course, end up dead. The larvae are not spared either when they wiggle past that area, the powder attaches to them and dehydrates them, thereby killing them.

You know what’s even more amazing about this flea powder? Less is actually more! You don’t need to pour a very large amount for it to work. Sprinkling just a few crystals is enough to completely take down all the fleas, including their long-distance cousins, like roaches, in your carpet.

This powder is odorless, and your children and pets can even come in immediately after you apply it. It won’t cause them any harm.

When considering flea treatment for homes, you definitely want something that comes with a long-lasting effect even when applied once. And that’s why you should consider getting the Fleabusters Rx for Fleas. With one application, the powder clings to carpet fibers such that even when vacuuming, the powder does not get removed, thereby enabling it to last.

In fact, the manufacturers of this product are so confident that they have an unconditional money back guarantee. Should this flea carpet powder fail to impress you or last an entire year, you can return the product for a full refund or a replacement respectively.


  • Active ingredients: Orthoboric Acid
  • Target insects: Fleas, flea larvae, and roaches
  • Where can be used: Indoors
  • Other features: Attaches to carpet fibers and so can’t be removed by vacuuming; neutral pH unsusceptible to fleas; kills fleas, their larvae, as well as roaches; works with even a very little quantity

But with this powder, you are sure to give these pesky and irritating things a good run for their lives. Only that they actually run into their death.
It is specially formulated to kill fleas at every stage in the cycle. So, it’s not just the adults that actually die, the eggs, pupae, and larvae also get destroyed with an application. It will also kill dog ticks effectively, especially the brown ones.

And in cases where you have a not-so-good smell coming from your carpet, it deodorizes the carpet and gives it a clean and fresh scent.

This 16-ounce can of freedom from fleas controls and prevents a re-infestation for a period of 365 days so that you don’t have to keep re-applying the powder to get rid of the fleas.
Here’s something you should keep in mind: This rug powder is not kid-safe and should be kept out of children’s reach.

Also, after applying it to your carpet, you’ll need to vacuum your rug. We advise you to do a thorough vacuum twice to remove the powder (certainly not its effectiveness) from your carpet.
You should also keep your pets out of the room where you’ll be sprinkling the powder to avoid adverse effects on them.

About flea carpet powders

Fleas… Even the very sound of the word sounds like a contagious disease and why not?

The name has become synonymous with doom and gloom. Fleas affect pet and human health and constitute a nuisance around the house too. Imagine coming home to rest and then finding a horde of fleas everywhere the light touches, right?

Anyway, there are many ways to send fleas packing from your home. Knowing that these fleas get into your house by attaching themselves to your pets (dogs and cats alike) when they go outside to play, it is important that you treat your pets with medication regularly as prescribed by a vet.

However, this medication will not solve the infestation problem that’s already in your home and that’s why you’ll need something else to join forces with the pills.

You’ll need the best flea carpet powders you can find and our guide is here to help you make that decision.

How do flea carpet powders work?

Flea powders work following a very simple process.

Now, when your pets bring fleas into your home, they go and make their homes inside your carpet and furniture. It is in these places that they live as well as breed.

If you remember elementary biology, you’d recall that when insects lay their eggs, these eggs mature into small, worm-like creatures called larvae before they metamorphose into full-fledged adult insects.

So, here’s what the flea powders do. By the time the egg has reached the larva stage, it feeds on the powder and dies. So, it never gets to the adult stage.

But how about the ones that are adults already? Flea powders kill them as well.

Different powders have different ranges of time within which they kill fleas and their larvae. Some are really rapid, while others might take between 4 and 6 days.

How reliable are flea carpet powders?

One thing that seems to be working in the favor of flea powders and makes them a more appealing option than other spot-on products is the fact that they are mostly affordable. Also, they are pretty multifunctional when compared to other similar products. For instance, aside from their uses on carpets, they can also be used on bedding, furniture, out in the yard and even on your pets themselves.

However, how reliable are they?

From research, it would appear that although flea powders are effective in flea treatment in the home, they are much more suited to that purpose than in direct application on pets. Flea powders should, therefore, not be considered an alternative to flea drops, tablets or collars, but rather, as a reinforcement.

For the most effective treatment

After spreading your flea carpet powder ensure that you do not vacuum until the powder has settled for at least an hour. But if the infestation is really bad then you might have to leave the powder on the carpet for up to 24 hours before vacuuming.

Remember that in combating a flea infestation, you will have to vacuum the areas where you’ve applied the powder for fleas (making more frequent vacuuming a necessity). Yeah, welcome to the struggle.

Pets pick fleas from the outdoor mostly and if your pet is one to spend most of his waking moments in the yard playing, then it might be a good idea to get a diatomaceous earth fleas powder.

Diatomaceous earth fleas powders are inexpensive and will work wonders in your yard by eliminating fleas and making the yard flea-free for your precious pet. It is relatively safe and poses low risks of toxicity.

In essence, flea powders do work but maybe not when applied directly to your pets. If you want a total flea annihilation, then combine flea powders with regular flea treatment and preventatives for your pets and you’ll be flea-free in no time.

What do flea carpet powders contain?


These are naturally-occurring extracts found in the flowers of chrysanthemum plants that grow in Japan, Europe, the Middle East, and Kenya. Pyrethrins are of six different types which include: Pyrethrin I and II, cinevin I and II and Jasmin I and II.

Pyrethrins work by affecting the nervous system of the insects and consequently causing repeated firing of the nerves which leads to the outflow of sodium from the cells and, ultimately, death. They are effective against fleas as well as ticks, lice, Cheyletiella mites and mosquitoes.

Because pyrethrins are easily degraded by stomach acids, toxicity in pets following ingestion is very low. And in those rare cases, symptoms (which include salivating, tremors, nausea, and seizure) disappear after 24 hours.


These are synthetic pyrethrins, meaning they are made in the lab instead of naturally. Although slower in action, pyrethroids give a longer effect than their natural cousins.

They cater to the same range of insects as pyrethrins but present higher toxicity, even though their toxicity is still low. This is because it’s a bit more difficult for them to be broken down in the guts of pets than pyrethrins. Should your pet present symptoms (which is the same as for pyrethrin toxicity), please see your vet immediately.

Insect Growth Regulators and Development Inhibitors

These include methoprene, fenoxycarb, pyriproxyfen, and inhibitors such as lufenuron, and diflubenzuron.

Insect growth regulators work against the fleas’ immature forms and keep them from developing into adults. When the larvae fail to molt, they shrivel up and die.

Development inhibitors, on the other hand, hinder the process of synthesizing chitin. Chitin is what forms the cuticle of the flea and if this isn’t formed the adult flea cannot exist.

Because these ingredients do not kill, they are best used together with an adulticide. They may prevent a re-infestation, but if you already have an infestation problem, they might not be your best bet. However, they are super safe to use.

Diatomaceous Earth

Flea powders containing diatomaceous earth are very effective in their function, however, diatomaceous earth does not come without its risks. And the risk is that the risks are not well-known which means that many will use this without taking precautions and might run into problems not knowing that it has the potential to be hazardous.

When getting a diatomaceous earth flea powder, ensure that you read the label carefully. It should have an EPA registration number and should tell whether or not dust masks are needed for the application, including other relevant information about the dangers of toxicity with exposure.

Generally, diatomaceous earth is considered safe at a concentration of 2% but with the prolonged exposure that flea control will demand, you might need to take steps to protect you and yours by reading the label and following instructions; ensuring your pets and kids are away while you apply the product, using a dust mask while applying, and applying only in areas that aren’t easily accessible to people and pets.

Buyer’s guide

Chemical products

If you are facing a heavy flea infestation, products containing insecticides are widely considered to be the most effective. Pesticides such as permethrins (which kill adult fleas stone-dead) and insect growth regulators (IGRs) like pyriproxyfen work in combination to eliminate all stages of the flea life cycle – even eggs!

Flea carpet powders that use insecticides are their active ingredient can effectively control even large infestations and are generally safe to use around the home. The major advantage of using a chemical product is that many powders are formulated to kill eggs and well as larvae and adult fleas, which means fewer applications and faster extermination.

Natural products

If you’d rather avoid using chemicals at home, there are several natural alternatives to choose from. Flea carpet powders containing certain plant extracts and essential oils, such as thyme, have strong repellent effects that can help to get your flea invasion under control.

Diatomaceous earth is another non-toxic solution to your pest control woes. This naturally-occurring powder kills adult fleas (and other insects) by drying out the waxy cuticle covering their bodies, causing them to shrivel up and die. This can be scattered on carpets around your home to kill adult fleas and larvae, though it must be reapplied more regularly than chemical powders. This is necessary to take down any newly-hatched fleas, as diatomaceous earth will not kill the eggs.

Natural remedies are best used as a preventative measure, or to control minor infestations. If you have large numbers of fleas in your home, products containing insecticides may be necessary to quickly and effectively remove the larvae, adult fleas and eggs from your carpets.
