Think of the dynamics of this. If in fact all the pines will be consumed by beetles(and I’ve seen how fast they destroy a tree), this should become self limiting within that geographical area. Kinda like ebola in a static population group/area.

It doesn't self-limit. The forests around Cedar Breaks National Monument Utah were infested in the late 1980's. The forest is completely dead now, and the infestation has spread from there.

The “static area” is North America. These beetles have destroyed a ton of trees in British Columbia. The only hope is a uper-killing frost. I forget the termperature but the larve die somewhere around 20 or 30 below. If it gets that cold and stays there they can be stopped.
