Why does diatomaceous earth kill bugs but not people? I heard that it’s in our food sometimes. Someone even recommended eating it.

There’s an excellent reason why diatomaceous earth kills bugs but not people. Chiefly, insects have exoskeletons that are damaged by the silica in diatomaceous earth. When you use diatomaceous earth for bed bugs, it causes them to dehydrate and die. But it won’t do the same to humans. Our skin protects us. The only danger is breathing in too much of the dust.
In fact, people, cats, and dogs can all benefit from eating small amounts of the diatomaceous earth if it’s food-grade and pure. For one, it helps with digestion. And it also contains healthy minerals like calcium and magnesium that boost your diet. But avoid consuming pool grade earth. Manufacturers harvest it from saltwater sources. Therefore, it may contain contaminants.
Besides taking it as a supplement, you can use diatomaceous earth to protect your house and garden from pests like ants and as a natural roach repellent. This is because it forms a natural barrier to crawling insects. And some folks like to shine up their silver or scrub their toilet with it since it’s a gentle abrasive. Others use it to absorb musty odors and remove carpet stains. In fact, you can view the whole list of ways to get the most from the diatomaceous earth in this article: https://www.tipsbulletin.com/diatomaceous-earth/
In summary, this is a safe, natural product that can enhance your health. You don’t need to fear diatomaceous earth–instead, use it to help you live better.
