話題沸騰中の How Does Diatomaceous Earth Kill Fleasについて、主要な情報を分かりやすく掲載しています。

First off, let’s clear up the biggest confusion. Diatomaceous earth (DE for cool insiders) is not dirt from your garden. It’s the fossilized skeletons of tiny aquatic creatures called diatoms. These little algae built their shells out of silica, and when they died millions of years ago, they left behind a chalky, sharp-as-a-razor powder. Imagine a billion microscopic glass shards, but so small you can’t feel them with your fingers. For a flea, though, it’s like walking through a field of broken beer bottles.
