What is diatomaceous earth?
If you are going to use the product, I think it’s important to know what you are getting into. So what exactly is Diatomaceous (die-uh-toe-may-shus) Earth, abbreviated as DE, and where does it come from? Diatomaceous earth is powdery dust that is made from crushed diatom fossils.

The diatoms are harvested when they become fossilized and then turned in products.
How does diatomaceous earth work to kill ants?
Most people believe that diatomaceous earth is poisonous, but this is not the case. DE can be found in thousands of non-pesticide commercial products that people buy and use every day. Some products that contain diatomaceous earth include beverages, foods, medicines, skincare products, toothpaste, water filters, and many other items.
Well, if DE is not a poison, how does it work to kill ants? When used as an insecticide, diatomaceous earth acts as a desiccant, meaning DE causes the ant to dry out and die. The ant does not have to eat DE to be effective. DE is abrasive, so when the ant comes in contact with, it tears apart the insect’s exoskeleton. As a result, the ant drys out and dies.

She tells them what to do, forage for food, build the ant nest, or protect and defend the mound from intruders. You can kill plenty of ants, however, until you take out the queen.
My best advice to you is to track down the ant colony. Find the ant nest and then sprinkle diatomaceous earth around the outer edges in a complete circle. For good measure, also apply DE to the top of the nest. The final step is to disrupt the nest so that the ants come out and go in defense mode.
The ants will swarm the nest, many of which will make contact with the diatomaceous earth and carry it back underground deep into the nest. At some point, the queen will come in contact with an already affected the DE will be transferred to her body, she will die, and your ant problem will be solved.
