How is it that bugs, who have the ability to evolve for survival over time, are still brought to their end by DE? I was just curious about that if anybody knows.

I use DE food grade once in a while. Not only has it been used for decades on pets and farm animals but it can be good even for humans as well. From what I understand of it is that Diatomes are very fine tiny microscopic organisms which are obtained from the plankton at the bottom of the ocean. If they were to be observed under a microscope they have razor sharp edges which is what will score the internal parasites or worms in an animal which in turn will cause them to dehydrate and shrivel up and die. To the touch DE food grade is so soft it feels similar to baking powder so it is not harmful to the animal itself. It can also be used as a flea treatment in the summer months which can not only be rubbed into the animals coat to skin level but it can also be used on carpets in the home. The fleas will try to walk thru the carpet fibers and if they brush up against these diatomes with razor like edges they will "score" their exoskeletal outside shell causing them to shrivel up and die. Same as on the animals coat. I personally use it in summer in my carpets and let it sit for over 24 hours before vacuuming it up. It is a great all natural way to handle both internal or external parasite in both the home or on pets. And that is what I understand of how it works. No chemicals to risk in the home or on pets...it's all natural.
