Flea powders work in a couple different ways, depending on the ingredients they contain. Below we will go over the common active ingredients found in flea powder, and how they work.

Boric Acid (Borate)

Boric acid is commonly found in a variety of insect control products. It is inexpensive, odorless, and remains active for up to a year. It works in two ways. Firstly, it will disrupt digestive enzymes in the flea’s stomach. Second it will absorb moisture from fleas’ bodies, causing them to dehydrate and die. It starts working right away on contact, because borate salts are abrasive to insect exoskeletons. The great thing about boric acid is it does not repel insects, so the fleas will return to treated areas to die. Boric acid will also work on eggs and larvae. You should see results from boric acid in two to three weeks. The reason it takes this long is because it takes a while for the current pupae to hatch and then die. Boric acid has low toxicity, and is safe to use in homes. The only known side effects are itching of eyes, skin, and throat, and these symptoms are rare.


Pyrethrin is another common active ingredient that is used in flea powders and other control products. It can also be used as an insect repellent in lower concentrations. Pyrethrin is safe for humans and most other animals, but should not be used around cats or fish. It is an organic compound, but there are a variety of similar synthetic insecticides that are derived from it, such as permethrin. Pyrethrin and its derivatives all work by targeting insect’s nervous system. Their nerves will rapidly fire repeatedly, and the end result is death. This insecticide is most effective on adult fleas.


Nylar is the trademarked pesticide pyriproxyfen. It is used in flea powders, sprays, and topical treatments for pets. It believed to be very safe for use around the home, and has no effect on people or pets. It only works on small insects. Nylar is a flea growth regulator that affects flea’s hormonal responses. Essentially it stops the flea eggs from hatching, and the flea larvae from being able to pupate into adults. Thus, no new generation of adults can lay eggs and continue the infestation. Keep in mind, it does not kill adult fleas. For the infestation to end, you will have to wait for the current adult fleas to die off.

How to Use Flea Powder

To apply the flea powder, lightly sprinkle it on the carpet’s surface evenly. Using a mini duster can make applying the powder much easier. The powder will sit on the surface of the carpet, and you might need to work it in deeper. In order to effectively get the powder to the bottom of the carpet, where fleas live and breed, push it in with a soft broom or brush. You may consider applying the powder at night when there is less activity around the house. Let the flea powder sit overnight, and then vacuum over the area in the morning. The vacuuming will not make it less effective, but will suck up any excess powder and dead fleas. Keep vacuuming at least once a day for two weeks after applying flea powder.

Where to Use Flea Powder

Obviously you will want to apply the flea powder to your carpets and rugs. However there are certain areas to focus on that might otherwise be ignored. Make sure you get the powder in carpet corners, under furniture, and in any other dark, undisturbed areas. Fleas like to hide in darkness, and prefer locations that are undisturbed where debris can build up. You can also use the flea powder on sofas, pet bedding, and kennels.
