Diatomaceous earth can be used to repel cockroaches.
There are two types of diatomaceous earth commercially available and they have specific differences. The food grade variety has many uses and is safe for human and animal consumption. Pool grade, also known as garden diatomaceous earth, is toxic to people and animals and should only be used in swimming pools.
Food-grade diatomaceous earth grades are the most common and have many applications. They can be mixed with grains that are stored for animal and human food to repel mealworms and other pests, and to prevent the grain from going hard. They are safe to use as insecticides indoors and are also very effective when used outdoors to repel and kill insects. They work by creating small abrasions as insects crawl over them, which in turn causes loss of body fluids, resulting in dehydration and death.
Diatomaceous earth can help prevent fleas, which are tiny insects that bite and suck the blood of humans and animals.
Diatomaceous earth is also an effective dewormer for livestock and pets. It can be applied to dogs and cats to repel fleas and ticks; cats are dewormed as they lick and clean themselves and ingest the particles. It also kills flies and their eggs. Indoors, it can be used to repel and kill bedbugs, cockroaches, crickets, moths, and many other unwanted insects.

Most of us have eaten diatomaceous earth in small amounts without realizing it, because it is present in many of our grain products.
Pool grade diatomaceous earth can be used for pool treatment and as an insecticide in gardens and decks. It is used in the same way as the food grade type and produces similar results. However, diatomaceous earth for swimming pools often contains other toxic pesticides and chemicals. It’s best to use food grade for everything except pool filters.
Both types of diatomaceous earth are made from the bony remains of algae that live in fresh and salt water, but can be harmful if applied incorrectly.

It is also very irritating to the eyes and dries out the skin. Gloves must be worn when using this product.
