How Does Diatomaceous Earth Work?
Inert dusts, like diatomaceous earth, kill insects by desiccation. In other words, the dust removes the outer layer of wax or grease that is a part of an insect’s exoskeleton. The dust absorbs waxy fats and oils from the epicuticle or skin of insects and other invertebrate pests. After the insect’s coating is removed, it cannot retain water and dies from dehydration.
Replace Insecticide with DE for Bed Bug Control
DE is a common insecticide replacement for treating bed bug infestations. When treating a pest infestation, horizontal transfer of insecticides is important for effectiveness. In a nutshell, horizontal transfer describes the process of one insect transferring the active ingredient of a pesticide among other insects in the population through contact. Recently, 2013 study demonstrated horizontal transfer of diatomaceous earth in the common bed bug. This is important because bed bugs live in hard-to-reach places and horizontal transfer is needed for effective control.
Insect Resistance to Insecticides
Over the past several decades, insects have developed resistance to many chemical insecticides. An article presented at the Rutgers Entomology Centennial Symposium on Insecticide Resistance: Mechanisms and Management spoke to the challenge of insects’ ability to adapt and develop resistance to chemical insecticides.
“The spread of genes for cross and multiple resistance among insect pests has rendered most of our present insecticides obsolescent, and very few novel insecticides are under development as substitutes,”
Robert L. Metcalf
Genetics and intensive insecticide application are two significant factors that contribute to insecticide resistance. Insects with genes that resist a particular insecticide or class of insecticides survive and are thereby “selected” to pass on their resistant genes to later generations.
Insect Resistance to Diatomaceous Earth
Diatomaceous earth is not a chemical insecticide. Diatomaceous earth is a dust-like substance found in nature. It kills insects by wearing away their protective was or oil on their skin, which leads to dehydration. Because DE acts as a desiccant, it is much less likely for insects to develop genetic resistance in the same way as chemical pesticides.
The US Department of Agriculture on DE & Insecticide
Tests conducted by the United States Department of Agriculture have demonstrated DE to be more effective than malathion in controlling a variety of insects, including the grain borer, rice weevil, and confused flour beetle. Tests showed that with proper climatic conditions and application, diatomaceous earth could be effectively used on field crops as well. A benefit of this would be the reduction of the amount of chemical residues in water, soil, and atmosphere.
Diatomaceous Earth as an Insecticide Replacement
Diatomaceous earth can be used as an insecticide on a wide variety of insects including:
- Flea Beetles
How to Apply Diatomaceous Earth
You can purchase diatomaceous earth to replace insecticide use right here at Earthworks Health. We also sell different applicators you can select. Some applicators are small and others are large and run on a motor. Dust applicators work best in the garden. It’s best to always wear a dust mask when applying diatomaceous earth. When applying, make sure to cover the top and underside of all the foliage with the dust. A good time to apply is following a light rain or early in the morning when the dew is present.
When applying DE in the house for bedbug control or other insect control, DE should be applied along baseboards and the base of furniture.

Scientific studies have shown diatomaceous earth to be an effective replacement for insecticides. It’s been used for thousands of years, and surprisingly enough, insects are unable to become resistant to it. Knowing this, if you’re looking for a safe and chemical-free replacement for pest control, diatomaceous earth is a great choice.
