Customers ask us questions every day and we love providing answers and education about our products! Below are some of the questions we see most often. If your answer is not on this page, don’t hesitate to give us a call, email, or fill out our contact form.
How can something that kills bugs not be harmful to my pets?
Diatomaceous Earth (DE) kills insects by physical action, not chemical. Hundreds of the microscopic particles get all over the insect’s body. As the insects move, it scratches the waxy coating off of them, they dehydrate, and die. Because the particles are so small, they cause no harm to pets.
Is this product dangerous to inhale?
Food Grade DE and Crawling Insect Control DE is often confused with Filter Grade DE. Filter Grade DE starts out as Food Grade, but is then heated to about 1,000 degrees. After this, chemicals are used to crystallize it. This works great for filtering but is dangerous to people and animals. The World Health Organization has reported that crystalline silica in excess has been known to cause health problems. Breathing the crystallized product over long periods of time has been associated with an increased risk of lung cancer.
Perma-Guards’ Food Grade DE and Crawling Insect Control DE is less than 1% crystalline silica. Daily use of Food Grade DE for people, pets, and around the home is safe as is Crawling Insect Control DE for all your bug killing. Like any other dusty product, it’s best to wear a dust mask when handling the product.
Where do you get your diatomaceous earth?
We sell the purest food grade diatomaceous earth available from Perma-Guard. The product comes from the purest silica mine out of the 4 mines found in this country. This mine is an ancient fresh water lake bed located in Reno, NV.
Do you have pricing for large amounts of DE?

Can I pickup my order myself to save on shipping costs?
Yes. We are in Norfolk, Nebraska, and we can also arrange for pickup in Omaha, Nebraska. If you are nearby, this can be a big savings!
Does DE ever get old or expire?
No, diatomaceous earth will never expire. In fact, it is already thousands of years old! Be sure to keep your product sealed and away from moisture and liquid exposure.
Can I get an SDS sheet on DE?
Why don’t you have any information regarding the human consumption of DE?
In their work to protect the public health and ensure accurate product claims, the Food & Drug Administration has determined that the scientific evidence is not yet strong enough to issue an authorizing regulation which would endorse the human consumption of diatomaceous earth. Until then, we are unable to legally provide information regarding those uses of diatomaceous earth. We appreciate your understanding that we must comply with all laws and regulations in order to provide you with these great products.
