Alright, to me most of this is still theory. I am slowly increasing my collection of supplies and I have heard horror stories of $100's of materials going to waste because someone didn't take care to properly sanitize or "zap" the "cool feathers" they got from a buddy etc. and just added to their collection.

What are the first clues that you may have a problem?
1) Do you see actual bugs?
2) Things start to smell funky?
3) Materials start coming up missing? (I have another theory on this problem, but I could be wrong)
4) You start getting bug bites?
5) Gas prices increase?
