Bed bug infestations and household pests can be frustrating, but natural pest control methods are gaining attention as safe, eco-friendly alternatives to conventional insecticides. Among the most discussed solutions are diatomaceous earth (DE) and cloves, both known for their potential pest-repellent properties.

This guide explores the evidence-based uses of these natural substances, how to apply them properly, and what precautions to take. While these remedies may support pest management, they are not substitutes for professional pest control in severe infestations.

What Is Diatomaceous Earth?

Diatomaceous earth is a naturally occurring soft sedimentary rock that crumbles into a fine white or off-white powder. It is composed of fossilized diatoms, a type of algae with silica-based cell walls.

When used in pest control, food-grade diatomaceous earth can be a helpful tool. The powder works by physically damaging the exoskeleton of insects such as bed bugs, ants, and fleas. According to the National Pesticide Information Center (NPIC), DE causes insects to dehydrate and die, making it a mechanical insecticide rather than a chemical one.

Important Note: Only use food-grade DE indoors. Pool-grade or industrial DE is not safe for home use or inhalation.
