Diatomaceous Earth

By absorbing the oils and fats from the exoskeleton's cuticle, Diatomaceous Earth causes insects to dry out and die. Because of its sharp edges, it is abrasive, which speeds up the process. It'll keep working as long as you keep it dry and undisturbed. Besides, this Diatomaceous Earth is a powder produced from fossilized algal silt found in bodies of water. This is also used to manufacture building materials such as bricks and blocks. Later on, it gained popularity in the world for a variety of industrial applications.
