Food-grade diatomaceous earth is the only version you should use for pest control. Why? Because "regular" or pool-grade versions are chemically altered and dangerous to breathe.
Think of diatomaceous earth as like tiny shards of glass for insects. While it’s just a soft powder to us humans, it works by physically dehydrating pests from the outside in.
So what’s the difference between diatomaceous earth food-grade vs insect killer products? Well, it often comes down to purity and labeling.
The food-grade version is safe to use in grain storage or as a supplement.
The versions specifically labeled as "insect killers" often contain added attractants or surfactants to make them more effective against stubborn infestations.
For a homeowner or a manager of a food business with pests, choosing food-grade diatomaceous earth is important. It ensures you’re managing pests without introducing the respiratory hazards found in industrial-grade versions used for swimming pool filtration.
Why risk using a product that wasn't designed for your environment? By sticking with food-grade diatomaceous earth, you get both the power to stop crawling insects and a safer environment for your family or your customers.
