My fabric stash (yes... I do have one...) is in our basement. In summers, the temps are very cool... but we heat with wood, and it's super warm down here in the winters. So far I have not seen any bugs other than spiders! We have a little supply of wood down here, seasonally, and yes... we do get SOME of those insects due to them hiding out on the firewood. My folks had silverfish in their TYPING paper supply in the hot attic when I was a kid. There was no way my mom could get rid of them. They were awful. Thank you for the warning! I am now aware! (yuck, huh?)
