Buying Guide

While diatomaceous earth is a natural pest control product that’s proven safe, there are some key points to consider before you decide on the right product for your needs. 

  • Quantity: The amount of diatomaceous earth necessary to control your pest infestation depends on the extent of the outbreak. Look for the estimated area coverage before making a purchase, but too much DE is better than too little. Fortunately, diatomaceous earth is already ancient, so it has an extremely good shelf life. If it stays dry and is properly stored, it will never expire.
  • Dryness of the area: Make sure that the area is dry before applying your diatomaceous earth pest control product — DE is rendered mostly ineffective when wet. Prior to application, consider blocking off high-traffic areas to ensure the product stays dry and undisturbed. 
  • Food grade: If you’re using diatomaceous earth for pest control, the product doesn’t necessarily need to be food-grade. While most if not all DE products are designed to be non-toxic and safe to use around pets and family, food-grade diatomaceous earth is more versatile, as it can be used as a health supplement. 
  • OMRI designation: Many diatomaceous earth products have an Organic Materials Review Institute (OMRI) designation. This means the product has been tested by OMRI and passed their certifications for the purity of ingredients and for organic use. 

 

 

FAQs

  • What makes diatomaceous earth an effective form of pest control? 

Diatomaceous earth kills insects by drying out their exoskeletons. The edges of the diatoms are sharp, which speeds up the process. Keep in mind that DE must be kept dry in order to be effective.

  • What precautions should I take before using diatomaceous earth? 

We recommend wearing a dust mask when applying DE to avoid accidental inhalation. Make sure that pets or children aren’t in the area when you’re applying the powder and that surfaces are dry. Follow instructions as directed on the product packaging and store any leftover powder in a dry area such as a shed or garage. 

  • Can I use “pool grade” diatomaceous earth for pest control around my house? 

It is not recommended to use pool grade DE as an indoor pest control solution. The high silica content is toxic if consumed by pets or children. Stick to using food-grade or simply non-toxic diatomaceous earth intended for pest control.
