What is Diatomaceous Earth and How Does it Work?
Diatomaceous earth (DE) is a natural, organic powder derived from the fossilized remains of tiny aquatic organisms called diatoms. It works by dehydrating insects and other small pests, causing them to die from water loss. The powder is made up of sharp, abrasive particles that cut into the insect’s exoskeleton, allowing moisture to escape and causing the insect to become dehydrated. This makes DE a popular choice for gardeners and homeowners looking for a non-toxic and environmentally friendly way to control pests.
When used correctly, DE can be an effective and long-lasting solution for pest control. It is important to note that DE is not a poison, but rather a mechanical killer that works by physically damaging the insect’s body.
