Diatomaceous earth (DE) is a naturally occurring sedimentary rock formed from fossilized diatoms. It’s known for its absorbent and abrasive properties, leading to various applications, including pest control and as a food additive. Food Grade Diatomaceous Earth is a purified form deemed safe for consumption by the U.S. Food and Drug Administration (FDA). However, understanding its safe and effective use is crucial.
While food grade diatomaceous earth is generally recognized as safe for consumption in small quantities (up to 2% in food), using it for pest control raises different safety concerns. Pest control applications typically involve spreading a more concentrated product throughout a home, increasing the risk of inhalation. Breathing in DE dust, even food grade, can irritate the respiratory system. Higher concentrations also increase the risk of adverse effects if accidentally ingested or exposed to skin.
Unlike DE products specifically labeled for pest control, food grade diatomaceous earth lacks EPA registration and rigorous testing for efficacy and safety in pest control applications. Pesticide labels provide crucial information on proper usage, required protective equipment, potential hazards (indicated by signal words like CAUTION, WARNING, or DANGER), and first aid instructions. This information is essential for minimizing risks associated with pesticide use.
Pesticide labels for DE products outline specific directions for use, including application methods and dosage, ensuring effective pest control while minimizing risks. They also list necessary precautions and protective equipment, like wearing a dust mask, to reduce exposure. Additionally, labels specify the toxicity level using signal words, informing users about the potential hazards.
Food grade diatomaceous earth, while safe for consumption in regulated amounts, lacks these crucial safety guidelines for pest control applications. Choosing a DE product with a pesticide label offers significant safety advantages. These labels provide clear instructions for safe and effective pest control use, minimizing potential health risks to humans and pets.
When using any form of diatomaceous earth, certain precautions can minimize potential risks. Always wear a dust mask to prevent inhalation, especially during application. Protect your eyes with goggles and wear long clothing to minimize skin contact. Keep children, pets, and other non-essential individuals away during application and avoid applying DE in easily accessible areas or near air vents, where it can easily become airborne.
Following these precautions and opting for DE products with pesticide labels for pest control ensures both efficacy and safety. By understanding the differences between food grade and pesticide-grade diatomaceous earth and adhering to safety guidelines, you can effectively utilize this natural substance while minimizing potential risks.
