Diatomaceous Earth for Bed Bugs – Complete Review

Before resorting to expensive and time-consuming professional treatments, you probably want to try to tackle your bed bug issue on your own.

What is Diatomaceous Earth?

Diatomaceous Earth (DE) is a fine, white powder with a multitude of uses. Some people choose to ingest Diatomaceous Earth for its supposed health benefits, but combating some types of bugs is the proven use for Diatomaceous Earth. Diatomaceous Earth comes in two different qualities: food grade and filter grade. You should purchase the food grade for use in and around the house in case anyone accidentally ingests the substance. 

The fossilized remains of tiny organisms called diatoms make up Diatomaceous Earth. These remains largely contain silica, a natural and common mineral found all over the earth. Although diatomaceous earth may look like flour or baking soda, on a microscopic level, it is much more abrasive. To us, it may feel like a mix between baking soda and sand, but its abrasive texture is what gives it so much power against small critters.

Diatomaceous earth kills bed bugs by scratching away at the waxy layer on the bed bugs’ outer shells. This waxy layer is what helps bed bugs retain the moisture in their body. So, once the diatomaceous earth has removed enough of this protective layer, the bed bugs will dehydrate and die. Unfortunately, diatomaceous earth only works to kill adult bed bugs, and adults bed bugs may not even be the majority of the bed bugs living in your home. Due to its inability to kill young bed bugs, we recommend combining using diatomaceous earth for bed bugs with other treatments. Using heat, such as steam cleaning or washing sheets on hot settings, has been shown to be effective against young bed bugs.
