As paper, particularly corrugated paper products age, the fluted medium is the first to degrade because of its chemical characteristics. This causes the paper to dramatically lose strength and give the appearance of crumbling. The crumbling exposes more of the starch-based adhesive which holds the layers of paper together. It is the starch adhesive that various insects thrive on.
