Earwigs are common household pests that can be a nuisance, especially during the summer months. While there are many ways to control these pests, one method that has gained popularity in recent years is the use of diatomaceous earth (DE). This article will assess the effectiveness of DE for earwigs and provide some tips on how to use it effectively.

What is Diatomaceous Earth?

Diatomaceous earth is a naturally occurring sedimentary rock that is made up of the fossilized remains of diatoms, microscopic algae-like organisms. It is a fine powder that can be used for a variety of purposes, including as a pesticide.

How Does DE Work?

DE works by dehydrating insects and other pests. The microscopic sharp edges of the diatomaceous earth particles cut through the exoskeleton of the insect, causing it to lose moisture and die.

Is DE Effective for Earwigs?

Yes, DE can be effective for controlling earwigs. When applied correctly, it can kill earwigs and other pests within 48 hours. However, it is important to note that DE does not provide long-term control and should be used in combination with other pest control methods.

How to Use DE for Earwigs

  1. Choose a high-quality food-grade diatomaceous earth product.
  2. Apply a thin layer of DE in areas where earwigs are known to hide or travel, such as under rocks, in cracks and crevices, and around the perimeter of your home.
  3. Reapply the DE every few days or after rain or heavy dew.
  4. Wear gloves and a mask when applying DE to avoid inhaling the dust.

Tips for Using DE Effectively

  • Use a dust applicator to apply DE evenly.
  • Apply DE to dry areas to prevent clumping.
  • Keep pets and children away from DE-treated areas.
  • Monitor the effectiveness of DE and switch to another pest control method if necessary.

Yes, food-grade DE can be used on plants to control pests. However, it is important to apply it in a thin layer and to avoid getting it on the leaves or flowers of the plant.

In conclusion, diatomaceous earth can be an effective method for controlling earwigs when used correctly. It is important to choose a high-quality product, apply it correctly, and monitor its effectiveness. If you have a severe infestation or are unsure how to use DE effectively, consider consulting a pest control professional.
