How It Has Evolved Over TimeWhen it was first discovered in the late 1700's the original Moth Ball was in a cone shape and very toxic to the human body, as well as being very flammable. Later then in the 1850's it was then started to be used as pesticides, yet still very toxic. In the 1900's it was then recreated to be less toxic, included paradichloribenzene to help create an appearance of a crystal, as well as the shape being a sphere instead of a cone.
