Make sure that you’re using food-grade DE and not pool DE. The latter is very abrasive and can be dangerous to humans and pets.

To boost the effect of DE, you can mix it with an ant attractant. Once the ants get lured and the DE sticks to their bodies, they will bring it to the colony. It will result in exponential death.
