At first, you notice that your dog or cat seems to be itching a bit more than usual. You attribute it to the humidity or maybe because your pet played in the dirt.

But soon enough your furry friend is in a flurry, her legs reaching all parts of their body trying to scratch and itch. That’s when you notice the little blood sucking invaders: fleas.

Has this ever happened to you? Well, you are not alone.

Fleas are every pet owner’s nightmare. They can make even the most docile animal distressed. Fleas love to make themselves comfortable in your pet’s bedding, crate, or kennel. Are you safe? Not really.

Fleas live off the blood of warm-blooded animals, of which you are one. So, they will bite you as well, although they will not invade your bed or stick to your skin like they do with animals. Unfortunately, they love to hide in the carpets and rugs.

But before we look at them keenly, let’s see how they work and how to select the best option.

How Do Flea Carpet Sprays and Powders Work?

Does flea powder work? Are dog flea sprays effective? These are questions I see often, and today, I’ll let you in on more beyond the typical yes or no.

The science behind flea carpet powders and sprays is quite simple. They kill off the larvae before they get to maturity. Larvae is the next stage a flea egg gets to before it turns into a fully formed flea. When the eggs hatch and form larvae, they begin to feed, but in this case, they feed on the flea powder and die.

The powders and sprays do not spare the adults either. They eliminate fleas within a week of spraying or by just placing the powder on the carpet.

Flea powders are highly recommended because they target fleas during the growth process and the possibility of inhalation or physical contact is pretty low. Sprays, on the other hand, can kill almost immediately and inhibit the growth of fleas, but the chances of exposure to the chemicals is relatively high

It is important to note that the growth process takes place in your furniture or carpets, which are the breeding grounds for fleas and not on the actual animal.

However, if your dog is infested, it would be best to take her to a professional. Watch the video below to see how those itchy blood suckers are removed :

Along with the application of the powders and sprays, you must make vacuuming a priority. Also consider using diatomaceous flea powder for your yard, which may be the primary flea breeding ground. This powder is safe for both pets and humans.

When using any of these solutions, remember: less is more. Don’t overload your carpet with the powder or saturate it with the spray. Instead, drizzle the powder lightly, and using a brush or broom, tickle your carpet lightly to allow the power to fall through to the bottom to reach the fleas.

Carpet powder is only one of the solutions available today. You can read here all about the different methods of getting rid of fleas on dogs.

Are Flea Carpet Powders and Sprays Safe & Reliable?

Most flea powders on the market allow you and your family to stay in the house even while using it. Unless of course, you are using professionals who come armed with industrial chemicals, then you have to vacate the house for a couple of days.

Flea powders contain Insect Growth Regulators (IGR). Their role is to inhibit the development of the larvae. It kills them off. Methoprene is one of the common IGR you will come across.

The US Environmental Protection Agency (EPA) has allowed the use of methoprene in insecticides and other growth regulators, like flea powders. This substance is non-toxic when inhaled or even ingested by your pet or yourself. It is not a carcinogenic substance nor does it affect reproduction in your pet when ingested.

In fact,  in mammals, it is excreted in urine and fecal matter after being broken down. Other trade names for methoprene include Apex, Altosid, Minex, Dionex, Kabat, Diacon, Precor, Pharorid, and ZR-515.

Other non-toxic substances found in flea powders include fenoxycarb, lufenuron, and pyriproxyfen. All these substances cause no side effects when they come in contact with your skin, but they may irritate the eyes if they come in contact with them.

In addition, they have all been approved for use in insecticides and growth regulators by the EPA. You can also check out the EPA’s list of active ingredients that are eligible for use in minimum risk pesticide products.

Having said that, you must wear protective gear such as gloves, goggles, protective suits, footwear, and the like as a precaution when using any flea powders or sprays. This is according to the safety regulations put in place by the EPA.

For powders containing diatomaceous earth, you have to be careful about continual use. The more you use it, the more you become exposed to the dust and other substances therein. Although diatomaceous earth flea powder is considered a great solution for fleas in your yard, make sure that the area is off limits to your family and pet for a while, say, a two weeks or three, after application.

One of the well-known side effects of diatomaceous earth is the drying the skin, so make sure you wear gloves when handling it. Since it is all natural, it can be safely applied to the coat of your cat or dog but avoid the eye area.

After a few days, wash it off with an anti-flea shampoo that is completely natural. This is to ensure the shampoo does not strip the animal further of natural oils on its coat after all the diatomaceous earth has stripped it already because of its drying effect.

When it comes to reliability, it depends on the powder. Some kill off the larvae within 2 days, while others take as long as 12 days. In some cases, the powder continues working for a few more weeks after application.

What To Consider Before Purchasing Flea Sprays and Powders

How Severe Is The Infestation?

In an ideal situation, you get wind of the presence of fleas before they become an army. However, it is quite hard to do that. Thus, it is always recommended to treat their presence as an infestation. This means using the powders or sprays together with an intense clean up of the furniture, carpets, and rugs.

In some cases, you may need to take the carpets and rug for professional cleaning after the treatment and call in professionals for furniture cleaning.

You may also need to change your dog’s bedding completely if the infestation is untenable.

The Natural Or Synthetic Route

If you prefer a natural solution, you can opt for Diatomaceous Earth flea powder, which is made from the fossils of microorganisms known as diatoms. A synthetic solution that involves the use of pyrethroids, lab created agents that mirror the effect of natural pyrethrins from the pyrethrins plant, is also available. Some people prefer the latter because the synthetic flea powder works for long after application.

Your Family

Do you have anyone or a pet with a health vulnerability in your home, including cancer or respiratory issues? This will to a large extent determine which powder or spray you opt for. Choose non-toxic options that have little to no effect on their health. If you find none that is safe for them, you may have to move them away from the house for a few weeks as you treat the space.


You must opt for the most effective option that still offers you safety. Check how long it lasts, what the flea carpet powder reviews say about its results, and how much you will need. For the best results, make sure you treat your pet and home simultaneously.

Damage To Your Property

Some sprays and powders may damage your carpets and rugs. This is a risk you must be willing to take. It is, therefore, important to prevent fleas from entering your home in the first place by taking measures, like treating your yard for fleas using diatomaceous earth and keeping your dog away from infested areas.


Do your own research about what are the best flea solutions for your home and pet instead of just relying on friends and family. What works for them may not work for you because of the nuances of your home.

Besides, you may have very expensive furniture and rugs or your animal may be sensitive or your family member may be in a vulnerable health space.

Also, before use, read the instructions carefully and wear the right protective clothing, even if it just a dust mask.

However, users who have allergic reactions to essential oils must wear protective gear to keep the solution off their skin.

You and your pet are all fair game for these blood sucking creatures. Thankfully, using the best flea powder for carpets or any of the listed top sprays will not only bring relief within days but also eliminate the problem for a good duration of time.
