How it works: When insects crawl through the diatomaceous earth, the microscopic sharp edges work like shards of glass, slicing open their exoskeletons. As soon as the waxy outer covering of the bug is pierced, the insect will slowly begin to dry out. DE is also excellent at absorbing moisture, so the more the insect contacts the diatomaceous earth, the faster it will dehydrate. Thus, the actual means by which diatomaceous earth kills bugs is through desiccation.
How to Use: Just sprinkle it thoroughly in affected areas such as plants leaves or around plants.
