I know the lesson of packing thing carefully all too well. I had bins of textbooks/papers from grad school which I stored in a shed in my parents backyard. 3 years later, my parents told me I absolutely had to clean them out and take whatever I wanted with me as anything left behind would be discarded. When I removed the lids I found bins filled with what appeared to be soil at first glance but was actually very well mulched and composted textbooks/papers that had been completely and thoroughly digested by a significant number of large white grubs. Being a biologist by education I was fascinated by these paper-eating grubs that managed to turn a pile of very expensive textbooks into processed and decaying organic matter whose origins were absolutely impossible to discern. Of course, after the fascination wore off, I became incensed at these little fuckers that had destroyed what was easily thousands of dollars in materials. I proceeded to dump the bins out and squish every single last one of them, which I had to clean up once my mother say the incredibly mess that had been made in my rage.

Overall, although costly and annoying, it was a lesson well learned.
