Diatomaceous Earth for Fleas on Cats – The Miracle Powder Your Cat Needs

Diatomaceous earth is an effective method of natural flea control. This natural flea pest control method is chemical free. You have control over the dose and the application.

Some background info…

Diatomaceous earth is made up of diatoms. Diatoms are the fossilized remains of a type of algae. DE looks like powder as shown below. DE can have an abrasive feel, similar to pumice powder. Although it looks like powder it is actually a natural form of mineral dust.

To kill fleas, the powder like DE, is sprinkled around the home and yard, in places where the cat hangs out.

It is the diatoms in the diatomaceous earth that scratch away at the waxy layer of the insect’s exoskeleton.  The flea dies because moisture from the body of the flea evaporates and the flea then dehydrates and dies. 

It does take more effort on your part than putting a flea collar on your cat or applying flea drops.

However diatomaceous earth, is a chemical free option which can also be used to get rid of fleas from around your home. Plus it works just as well for dogs.
