Diatomaceous earth (DE) is a naturally occurring substance made from the fossilized remains of diatoms, a type of hard-shelled algae. While some use it for pest control, it’s crucial to understand the facts about food grade diatomaceous earth and its effectiveness in killing bugs.
Some diatomaceous earth products, including “food grade” options, aren’t evaluated for risks associated with pest control. While some people might use these products to control pests, the risks and effectiveness remain untested and unknown. Users might not realize potential hazards and might skip precautions, leading to unfortunate situations. It’s important to remember that any chemical, even diatomaceous earth, can be harmful in large enough quantities.
Products specifically evaluated for pest control will state on the packaging that they kill, repel, or help get rid of pests. They will also have an EPA registration number. Pesticide regulators determine the toxicity of these products and inform users with signal words. They assess whether proposed uses are likely to result in high enough exposures to cause harm. Uses found to be too risky aren’t allowed on labels. If protective equipment, such as a dust mask, is needed, that’s also listed on the label. Furthermore, for certain pests like bed bugs, manufacturers must evaluate the product’s effectiveness in ideal situations. Pesticide labels help users minimize risks while maximizing potential benefits.
Understanding Pesticide Labels
Pesticide labels are crucial for safe and effective pest control. They include:
- Directions for pest control uses: The label specifies how much to use and where to apply it.
- Precautions: This section lists required protective equipment and other safety measures.
- Signal words: These indicate toxicity levels. “CAUTION” means low toxicity, “WARNING” is moderate toxicity, and “DANGER” signifies high toxicity.
- Effectiveness Testing: For certain pests, such as bed bugs, testing is required to demonstrate the product’s effectiveness under ideal circumstances.
Food Grade vs. Pesticide Grade Diatomaceous Earth
The US Food & Drug Administration generally recognizes diatomaceous earth as safe when added to food at levels up to 2%. However, pest control typically involves spreading a more concentrated product throughout a home. Breathing in the dust in such scenarios may be of greater concern. Higher concentrations also mean a higher risk if someone is exposed. Without a pesticide label’s guidance, uncertainties remain for the “food grade” user. However, you can always take steps to lower your risks by minimizing exposure.
Minimizing Risks When Using Diatomaceous Earth
Regardless of the type of diatomaceous earth used, it’s essential to take precautions to protect yourself, your family, and your pets:
- Choose products with pesticide labels and follow the instructions: These labels provide crucial information about safe and effective use.
- Keep children, pets, and non-essential persons away during application: This minimizes their exposure to the product.
- Wear protective gear: A dust mask, eye protection, and long clothing can significantly reduce exposure.
- Avoid application in easily accessible areas: Children and pets often explore areas near the floor, increasing their risk of exposure.
- Be mindful of activities that can stir up dust: Fans, vacuums, swinging doors, air vents, and high-traffic areas can redistribute dust, increasing exposure.
In conclusion, while food grade diatomaceous earth may have some pest control properties, its effectiveness and safety are not as well-regulated or tested as pesticide-grade options. Always prioritize safety by choosing EPA-registered products and following label instructions carefully.
