What is Diatomaceous Earth?

Diatomaceous earth (DE) is a naturally occurring, soft sedimentary rock that is crumbled into a fine white powder. It consists of the fossilized remains of tiny, aquatic organisms called diatoms. The unique structure of DE makes it an effective pest control agent. The fine particles are abrasive and can damage the exoskeletons of insects, leading to dehydration and death.

Using diatomaceous earth for pest control is not only effective but also safe for use around children and pets when applied as directed. It’s a preferred choice for those who want to avoid chemical pesticides.

How to Apply Diatomaceous Earth for Pest Control

Applying diatomaceous earth can be straightforward if you follow a few key steps:

  1. Identify the Infestation: Determine which pests you’re dealing with. Common targets include ants, bed bugs, cockroaches, and fleas.
  2. Choose Your Application Method: Use a powder duster or sprinkling can for even distribution. The Harris Diatomaceous Earth Crawling Insect Killer includes a handy powder duster to simplify this step.
  3. Apply to Affected Areas: Focus on cracks, crevices, baseboards, and other hiding spots. Apply a thin layer of diatomaceous earth where you suspect insect activity.
  4. Reapply as Needed: After cleaning, reapply diatomaceous earth to maintain an effective barrier against pests.

Pro tip: Ensure the powder remains dry to maximize effectiveness. If it gets wet, it will lose its pest-killing properties.

Benefits of Using Diatomaceous Earth for Pest Control

  • Non-Toxic: DE is a natural substance, making it safe for indoor and outdoor use.
  • Long-Lasting Protection: As long as the powder remains dry, it continues to be effective against pests.
  • Mechanical Action: DE kills pests physically, not chemically, which can be beneficial in homes with children and pets.
  • Versatile Usage: It can be applied in various locations, including gardens, attics, and basements.
